Summer is here! You’re not imagining it: it happened fast. And if it snuck up on you before you were able to make reservations for your favorite national park, you’re certainly not alone.
And since the pandemic, which caused a surge of outdoorsiness in the United States, many of the most crowded national parks have implemented timed-entry reservation policies during peak travel season. That means we’re not just talking about reserving your rental RV or national park campsite. We’re talking about getting in at all.
The good news is, many incredible national parks — in fact, most of them — have not implemented this policy. (That’s especially true if you visit one of the less crowded national parks, that are a bit further off the beaten path, but well worth the effort it takes to get there.) Some national parks with no timed vehicle entry reservations required include:
- Arches National Park
- Glacier National Park
- Grand Canyon National Park
- Joshua Tree National Park
- Mount Rainier National Park
- Yellowstone National Park
- Yosemite National Park
- Zion National Park
Of course, some of these parks may have specific features you’ll still need a permit for, like Zion National Park’s famous Angel’s Landing hike.
Either way, though, it’s still possible to plan an unforgettable national park vacation this summer, especially when you travel in an RV, which makes it easy to stay agile if plans change.
(Psst: We’ve written this guide for 2026, but reservation policies can change yearly, so make sure you double-check everything before your departure if you’re reading from the future.

Do All National Parks Require Reservations?
Absolutely not! In fact, this year, the list of national parks that do require reservations has significantly shortened. However, there are other types of reservations that may still apply, such as backcountry camping or hiking permits, or developed campground reservations if you’re traveling by RV.
It’s important to understand the different types of reservations we might be talking about. The strictest are the timed-entry permits that visitors are required to purchase ahead of time for some of the most crowded parks — and this is the type of reservation that has been discontinued in popular parks including Arches, Glacier, Mount Rainier and Yosemite in 2026.
However, as mentioned, you may still need reservations for campgrounds in the park, backcountry permits for backpacking or hiking specific features, and, of course, a reservation for your rental RV. (We’ve got you covered on that front.)
Here’s a quick look at those different reservation types side by side.
| Reservation Type | Required for Everyone? | Example Parks |
|---|---|---|
| Timed Entry | When in place, yes | Rocky Mountain National Park (details below) |
| Campgrounds | Always recommended | Most national parks during peak season (first-come, first-served may be available during off season) |
| Backcountry Permits | Yes | Angel’s Landing in Zion; Half Dome in Yosemite |
| Entry Fee | Not a true reservation, but entry fee is often required | Acadia National Park, Carlsbad Caverns National Park, Crater Lake National Park, Death Valley National Park, most others |
Best National Parks Without Reservations for Summer 2026
The easiest way to ensure your national park vacation goes off without a hitch is to simply choose from the broad list of parks that don’t require reservations this summer. (That list has actually since broadened, since a few of the major parks that had implemented timed-entry reservations have expanded their access by dissolving the policies.)
While, again, we always recommend confirming at the official national park website for each park before traveling, here are some of the best national parks with no reservations required for 2026.
Great Smoky Mountains National Park
One of the most beloved parks in the entire roster, Great Smoky Mountains National Park stands out from the crowd: along with not having a timed entry reservation requirement, this park doesn’t even charge an entry fee at the gate (although a paid parking permit is required for all vehicles parking for longer than 15 minutes).
At more than 522,400 acres, this park is vast and straddles the Appalachian ridgeline that runs between Tennessee and North Carolina, making it a premier destination for outdoor recreation seekers of all ability levels and ages. There are scenic drives and shorter, easier, family-friendly hikes for those looking for accessible outdoor activities. The park is also home to almost a dozen campgrounds, many of which are RV friendly (though size restrictions may apply)
RV Tip
If you’re looking for an RV-friendly campground with water and electricity hookups inside the park boundaries, Look Rock Campground is the one you’re after. It’s the only one that’s got ‘em — and as you might imagine, reservations can go fast.
Badlands National Park
The Badlands can make a good — no, great — RV getaway, thanks to its ease of access, otherworldly vistas, wildlife viewing opportunities, and Badlands Loop State Scenic Byway (SD Highway 240), which makes it all accessible even from the comfort of your vehicle. Of course, for more intrepid explorers, there are plenty of in-depth and strenuous hikes to discover, along with nearby boondocking opportunities that get you truly out there.
- Easy entrance
- Wildlife viewing
- Scenic Loop Road
- Boondocking opportunities nearby
RV Tip
Many RV sites at Cedar Pass Campground can accommodate larger rigs, but there are no sewer hookups, so arrive with full water and empty holding tanks or plan to use the campground’s dump station before leaving..
Theodore Roosevelt National Park
Less crowded than many other national parks, but still relatively easy to reach (unlike the truly least visited national parks, which include locations above the Arctic Circle in Alaska or Michigan’s hard-to-reach Isle Royale), Theodore Roosevelt National Park is the perfect combination of hidden gem and accessible — especially if you’re already planning a trip to the Badlands. Extend the fun of exploring western South Dakota, including opportunities to spot bison, bighorn sheep, elk and feral horses, with more scenic drives and longer backcountry hikes both on offer.
RV Tip
This is one park where the first-come, first-served campgrounds may actually work for lucky RVers, particularly if you arrive by early afternoon during the busiest (summer) travel season.
North Cascades National Park
Considered by many well-traveled people to be the most beautiful park in the lower 48, North Cascades National Park boasts truly storybook scenery, as well as some of the most rugged and adventurous backcountry hiking and camping opportunities there are. Tucked as it is so far north in Washington state, it also features fewer crowds than some of the heavy hitters (but make no mistake, it can get downright full in the busiest months of summer).
RV Tip
Reserve an RV site at the Newhalem Creek or Colonial Creek Campgrounds (North or South) well in advance for summer, as campsites fill quickly. Be warned: there are no hookups inside North Cascades National Park.
Petrified Forest National Park
Petrified Forest National Park is one that doesn’t scream at you with its scenery the way some of the others do. But if you can listen closely to what it’s whispering, you’ll be in on a desert secret that few ever get to share. We love this one especially because it’s an easy day trip from Grand Canyon National Park, one of the most famous and sought-after in the American system, and its drive-through-able experience makes it particularly suited for RV travelers.
RV Tip
There are no campgrounds or overnight RV camping inside Petrified Forest National Park, so plan to stay at a nearby private campground or public campground outside the park and explore it as a day trip.
Congaree National Park
Preserving one of the largest and last-remaining old-growth bottomland hardwood forests in North America, Congaree National Park is another one that doesn’t get quite as much attention as some of its higher-flying brethren — and it’s also one that doesn’t require timed entry. Its unique swamp ecosystem is ideal for paddling and canoeing, or simply enjoying from on-foot along its elevated boardwalk trail. It’s also, unlike some of the most famous national parks, easily located for many who live on the East Coast, just a short drive from Columbia, South Carolina. Oh, and did we mention that this is another wonderful national park without an entrance fee? Win-win.
RV Tip
Since there are, again, no RV hookups or dump stations inside the park, we recommend staying nearby and traveling in, especially since it’s less crowded.
Guadalupe Mountains National Park
Often overlooked, but a gift for those who travel to find it, Guadalupe Mountains National Park offers a hiking destination unlike any other. Along with its quieter-than-usual trails, the rock faces you’ll be looking at aren’t just any old stone: They’re actually the preserved remains of the most extensive Permian Period coral reef. Basically, it’s like you’re walking on the bottom of a prehistoric ocean. No big deal.
RV Tip
While there are campgrounds inside Guadalupe Mountains National Park that accommodate RVs (Pine Springs and Dog Canyon), neither have hookups — so be sure your rig is self-contained and fill up on water (and empty your wastewater tanks) before arrival.
Voyageurs National Park
A unique landscape tucked in the northern reaches of Minnesota just south of the Canadian border, Voyageurs National Park is the kind of place where you can go motorboating or kayaking in summer or sit under an aurora-glowed sky in an ice fishing hut come winter, and all manner of other to-dos in between. With its secluded islands, rocky shorelines, and incredible stargazing opportunities, this park offers a taste of the north to anyone who finds their way there, and is truly a must-see for all water sports enthusiasts.
RV Tip
While Voyageurs doesn’t require a timed entry fee and nor does it have an entry fee, it can be a bit difficult to get around in an RV. Indeed, much of the park is best seen by boat. We recommend staying on the mainland and making day trips up into the park; consider bringing a tent and doing some backpacking if you’d like a more immersive experience. (Permit fees and reservation requirements may apply.)
National Parks That May Still Require Timed Entry in Summer 2026
While policies do change annually, the list of national parks requiring timed entry this summer is a pretty short one: It’s just Rocky Mountain National Park.
To get into RMNP between May 22 and an as-yet-undisclosed date in mid-October, you’ll need to book your timed entry reservation ahead of time, pay the gate fee, and arrive on time. (Note: If you wish to access Bear Lake Road, you’ll need to specifically book that option, as it’s not included in the general timed entry admission.)
Other parks do have reservation requirements for specific roads or activities, and again, double-check the park you have in mind before you make plans, as these policies can change annually or even more often.
Here are some at-a-glance reservation requirements to expect for this summer.
| Park | Required Reservations |
| Rocky Mountain National Park | Timed-entry between May and October |
| Zion National Park | Hiking permit for Angel’s Landing |
| Yosemite National Park | Hiking permit for Half Dome |
| Haleakalā National Park | Reservation for sunrise access |
| Acadia National Park | Reservation to drive Cadillac Summit Road |
Why RV Travel Makes Visiting National Parks Easier
No matter which national park you’re visiting and whether or not you need to make a reservation, RV travel helps you easily combine adventure and convenience. When you’ve got everything you need for a comfortable camping experience right along with you, you’ve got the ultimate flexibility if reservation requirements or other plans change — life’s specialty.
Additionally, traveling by RV means you’ll be able to:
- Visit multiple parks on one trip, especially when you take advantage of one-way RV rentals
- Stay closer to the park entrance, or even inside the park if there are RV camping options available
- Pack everything one time rather than living out of a suitcase as you hotel-hop
- Cook some meals at home instead of relying on restaurants for every meal, which can help you both save money and stay on your healthy routine
- Bring pets (although keep in mind, they’re not allowed in many parts of many national parks, and RV rental policies around pets do vary)
- Travel more easily with family, thanks to lots of room to spread out and keep all your stuff (without having to rent expensive multiple hotel rooms)
Along with a nation-wide network of various RV types and sizes, RVshare also offers delivery and setup services for those who simply want to show up and enjoy their vacation. Check out nearby rentals today!
Tips for Visiting National Parks Without Reservations
When you are visiting parks that require a reservation, whether it be timed-entry or simply for the campground or a hike, here are our top tips for enjoying the experience to the fullest.
- Arrive early, especially during the summer season, so you can get set up before everyone else arrives and crowds the campground.
- Visit during weekdays when possible to take the edge off the crowds.
- Reserve campgrounds well in advance, even at parks that offer some first-come, first-served options.
- Have backup campgrounds nearby just in case — mistakes happen!
- Download offline maps, especially when you’re traveling to parks far off the beaten path.
- Carry extra water, particularly in parks and campgrounds that don’t provide potable water sources.
- Monitor weather conditions. Even in the summer, weather in some of the parks can change on a dime.
- Check park alerts before arrival for any last-minute need-to-know updates around road closures, weather exceptions, etc.
Planning a Multi-Park RV Road Trip
When you avoid reservation-heavy parks, you can easily pull together a multi-park RV road trip that you and your family won’t forget anytime soon. Here are some beloved loops that string up some unbeatable wilderness destinations with the least amount of friction possible.
Western Route
Start at Theodore Roosevelt National Park before heading south to the Badlands and finally finishing at Yellowstone.
Southeast Route
From Congaree, head northwest toward Great Smoky Mountains National Park. Plan for several days there before you finish out this southeastern trip at Shenandoah. (Keep in mind that you will need a reservation there if you’re planning to do the Old Rag day hike or backpacking trip.)
Southwest Route
Get a glorious view of the Southwest at some of its lesser-known national parks. From Petrified Forest National Park (which, yes, you might be coming to from the Grand Canyon), head east toward Carlsbad Caverns. Once you’ve explored the underground, it’s just a hop, skip and a jump down to Guadalupe Mountains National Park and some of the most epic above-ground fossils you’ve ever seen.
Frequently Asked Questions
Most of them! Even very popular national parks, like Glacier National Park and Yosemite National Park, have dissolved their timed-entry requirements as of summer 2026. The only major national park that does still have timed entry right now is Rocky Mountain National Park.
Yes. At almost all the national parks, you’ll need campground reservations to ensure you get a site, especially during the busy summer travel months. While some parks do set aside a small number of first-come, first-served sites each day, the best way to ensure you won’t be stuck without a spot is to reserve early.
No. Many national parks still charge an entry fee, even if they don’t require reservations. However, there are a few national parks, including Great Smoky Mountains National Park and Congaree National Park, that don’t charge an entry fee. (Other fees, such as parking permits, may apply.)
Yes! In fact, that’s one of the best reasons to choose an RV for your national park trip: it makes it way easier to see multiple parks without having to unpack and repack your suitcase and reserve a bunch of expensive hotels.
“Best” is highly subjective. However, Zion National Park, along with being one of the most sought-after parks in the list, has a campground with easy-to-use pull-through sites and electric hookups (though these spots are limited). The Grand Canyon, too, has a very RV friendly campground called Trailer Village RV Park.
The good news: the vast majority of the amazing national parks in the U.S. do not require timed-entry reservations — and when you travel by RV, you can easily string together a trip with multiple parks and maximum flexibility. While you should always check the park requirements before departure to help avoid surprises, rest assured knowing that the parks are open and ready for visitors. Just be sure you reserve your campsite (and your RV!) as early as you can.
