We were absolutely blown away by the groomed fatbike trails at Pearrygin. Granted, we hit the trails when the conditions were positively supreme but, nonetheless, the variety of trail and diverse loop possibilities was unlike any other place I've fatbiked. Kudos to the groomers (Steve, et al).
We took some time to rent a couple of fat bikes and ride along the lake. The West entrance offers the easier trails for folks new to riding in the snow. Its a short drive from the downtown area. If you ride your fat tires from the center be prepared for a tough uphill ride to the lake.
I just drove through the campground but have stayed overnight in past years. There are campsites right next to the lake. I'm not sure how many sites, but they seemed private and pleasant. There weren't many people when we drove through but it can be busy in the summer. I was there once when they had small radio controlled boat...
I can see why this is a favorite for kids out is easy to enjoy the lake and camp right on the edge. I just visited for a bit today and it doesn't work as well for day use not that much for trails to walk on and mostly just camping space.
The lake has the itch. We had welts all over for days. The boats buzz up and down the lake. The grass is green and constantly watered. The showers are clean. There are many groups that reserve in advance and act like they own the joint. Almost everyone burns a fire at night. This is a motorhome and speedboat paradise...
