When I got to redfish lake, it was already to late in the season (September) to camp here. I was still able to check out the campground and it had amazing spots right on the lake. There were nice restrooms and water available. I would like to come back here in the summer and camp here when the water isn't to cold and the campground is open!
If you show up to Redfish Lake on a busy weekend and all of the campgrounds are reserved/full, no worries. There is a bunch of free dispersed camping all along highway 75. A quick stop at the Forest Service Office down the road and I had a pretty good map of the forest roads in the area, but more importantly, a tip about free camping a stone’s throw away from Redfish Lake and Sunny Gulch campground. The road in is a bit rough with ruts and rocks, but there are several established sites with fire rings. There was a loop to the right with about 8 such sites and a loop to the right with about 5 sites as well as one that was hidden behind the site I chose that you had to walk in to(it was actually a nicer site than the one I chose, but I was tired and set up before I saw it on my explorations. There was one vault toilet that was not especially clean, but free is free, and if you really wanted to, you could walk less than a quarter mile across to the developed Sunny Gulch campground. There are no picnic tables or grills or tent pads, but definitely stone fire rings at each site so no worries as long as you brought your own camp chair. If you need a shower, head into Redfish Lake to use the public pay showers there.
