What to See and Do
Fishing and Boating
The Boulder Lake Recreation Area has a boat launch located on the south end of the lake. You can do just about anything you want on the water, including exploring the lake, fishing for trout, and getting in the water for some swimming and diving. It's a very large lake with a lot of places to explore, but you can also take advantage of this spot when looking for some peace and quiet. Try bringing some paddleboards or kayaks for a fun way to poke around the shoreline and find hidden places.
Wildlife Viewing
Aside from the trout in the lake, there are birds like eagles, geese, and other waterfowl to see, and land mammals may also be in the area depending on the season. These might include deer and other herbivores, but generally not large predators like bears.
Hunting
Hunting on the Boulder Lake Recreation Area is permitted on the grounds as long as you have the appropriate hunting license, as well as permits for the weapons that you own and carry. Fall is the best time for hunting due to the prevalence of local wildlife, so be sure to factor that into your plans.
Horseback Riding
The Boulder Lake Recreation Area is a fantastic place to take a horse. There are multiple stables located less than an hour's drive from the north campground, and the area itself is perfect for horses, lacking steep slopes or broken ground. You can ride around the rim of the lake or out into the surrounding preserve.
Picnicking
The Boulder Lake Recreation Area has tables set up for picnics at the two main campsites, which are on the northwest and southeast sides of the lake. The wind coming off the water and the beautiful views make this a great place to stop for lunch, and you can also use these facilities for breakfast after camping if you don't want to cook anything.
