We had the best stay at Serenity Lake, and we highly recommend it to others who are looking for a very low-key, relaxing weekend next to a beautiful little lake with outstanding hospitality.
Our group included three adults, two kids (first time campers) and a dog. The trip to Serenity Lake from Downtown LA took 3 hours on the way there (and 2 hours on the way back), so it was an easy drive. Allen greeted us at the gate, let us choose our campsite, gave us the lay of the land, and checked on us periodically over the course of the weekend. He, at various times, sold us firewood & ice (very convenient), blew up our pool floats with his air compressor, gave us tips about different parts of the lake, weighed in on a minor veterinary issue our pup had, and was just in general a totally kind and friendly person. The lake water temperature was perfect for a hot day, and we enjoyed watching sunrise and sunset right from our campsite. Pro tip: bring a device with the Skyview app. We were able to see Mars, Venus, and a bunch of constellations at night.
