Sinkhole Campground is relatively small compared to most of the campgrounds in this area. There are a total of 26 sites, and 13 of them can be reserved online in advance. These sites are spread over 2 loops, and each loop has 1 bathroom building with a men’s and women’s side. There is a campground host at the entrance, as well as an above ground water source (it does not claim to be drinking water but the info on Recreation.gov says it is drinking water). There are also dumpsters, but they have a sign saying it costs $3 per bag of trash to use them.
The bathrooms are nothing fancy, but they were clean, had toilet paper, working locks, air freshener, and they were regularly maintained. The vault toilets have the smallest seats I’ve ever seen, but again… they were clean. There was a “sewage” smell for about 10 feet around the bathroom building, but absolutely no smell inside other than the air freshener.
The campground was laid out in a different way than I’ve seen in any other campground, but it seems to work. Each site from 1-13 (as far as I noticed) was designed to be passenger side facing in a circular design that means you are not walking out to face your neighbor doing the same. We stayed in site 5, which is considered a group site with site 4. Thankfully, we were there with 2 other families, and we had both site 4 and site 5. Honestly, if we had been in either site without being there with the other family it would have been awkward. I’ve posted pictures because it will be very hard to explain. Basically, it’s 2 parking spaces that are extra-long, and one has an extra 10 feet at the back so the idea is that both RVs will open about 5 feet apart.
The campground is roughly a half-mile walk from the Willow Springs Lake. We ventured to the lake a few times and I swear each attempt to get to or from the lake resulted in a different path taken. It was odd to think, but I do not believe that these are highly traveled paths since there are multiple places you can drive right up to the lake and many of the trails looked overgrown. If you stay at Sinkhole, I strongly suggest you check out the lake. It was very pretty even with the water being roughly 5 or 6 feet low. We went fishing a few times and caught a few small trout, hiked about a quarter way around the lake, found a geocache, and just enjoyed the scenery.
