The site is gorgeous and so close to the Lake. The only thing keeping this from 5 stars is the fact that it gets very busy, even with limited access during COVID, try to go during the week.
Fallen Leaf Lake Campground is a sweet spot to get away. It is just south of South Lake Tahoe, and generally won't be as crowded. Weekends get busy for sure. We have been several times and my 3 boys loved being near the mountains, out of the heat, and so close to an awesome body of water. Hopefully next time we can get a site next to the lake. Either way, the campground is clean, and the sites are large.
I've taken my 3 kids a couple of times now, and it's such a great location along the Sonoma Coast. Not too many other areas that you can be deep into a wooded forest type area, then pop out on the cliffs over looking the vast Pacific Ocean. Great hiking, clean, and easy access to many other beach spots in either direction. Just a heads up, the roads to get here are winding and slow, but the scenery is worth it. Also, for what it's worth, this is a Northern California coastal experience, if you want swarms of people in bikinis sun bathing and walking along miles of flat perfect sand, then check out Southern California. Love this spot and will continue to visit.
