We stayed at the park due to it proximity to Crater Lake. The park is right on the highway but we didn't notice much road noise at all. As stated in other reviews it is mostly set up to cater to tents or rental cabins but has a few RV sites. It has plenty of family activities. Unlike a KOA, they do not nickel and dime you for use of their toys. They had a few canoes to paddle in the stream (no cost), a small but varied selection of DVD's (no cost) plenty of lawn games (no cost). The one thing you have to watch out for is the mosquitoes, they come out in force once the sun starts setting. If you happen to stay be sure to stop by the old Ft. Klamath site a mile or so up the road. The docent is very knowledgeable and friendly. If in the area we would stay again.
We decided to stay here based on the recording on their reservation line that sites were available for about $45.00. When we arrived we were offered a site at a cost of $70.00. No real explanation for the difference when questioned. I was tired so I just forked over the cash. The sites were roomy, clean, and well cared for. The bathrooms and laundry facilities were clean and modern. I was disappointed that for the cost the park does not have a pool. Due to the cost, I would not stay here again. I don't feel that a flat site and well mowed lawn justifies $70.00 a night. The cost coupled with the "no rigs over "x" years allowed" (mine is 2008)type attitude projected at the front desk is a big turn off for me. However if you do decide to stay, be sure to venture over tot he Sunriver Nature Center. They have an awesome observatory.
