Best in late fall when it's cooler. Less loud drunkards. Dont get me wrong, I love my cocktails but can get a little obnoxious. Can fit large RV's down a half mile rough road. I have been a few times in october/November in a 40 ft 5er. No hookups or onsite water. We went into Mt Ranier nat park and filled a 40 gallon tank from a waterfall along the road then pumped it into the rv. VERY large sites for RVS. Many smaller tent sites. We were there during military skydiving practice. Very cool!
