5700-foot elevation. 12 campsites on Grasshopper Creek. Two multiple-use trails originate near the campground. The Richardson Creek trail accesses a larger network, and a developed day use area at the trailhead invites day trippers to linger over their lunch. Bears may frequent the area; keep all food out of sight in approved containers and remove all food from area after eating. Mandatory food storage is required.
Lewis and Clark National Forest Grasshopper Campground is a nice campground in the Castle Mountains. As you enter this campground you find a trail head to the left and then a picnic area to the right. The campsites start right after the first of two vault toilets for the campground. At the beginning of the campground loop, right behind the registration box you will find the hand pump for the campground. A creek runs right through the middle of the campground. One nice feature of this campground is once the campground gates are closed and locked, you can still drive to sites 1 and 2 as they are before the closure gate, so as long as you can still drive up the road you can camp. Each site has a picnic table and a fire ring. I did notice at least one site also had a BBQ grill in addition to the fire ring. Sites are $10 per night with a 16 day stay limit.
