Despite the name, there is are no caves that one can see at the lake. This lake is a very small hidden desert treasure. There is a lakeside campground with few campsites that fill up very quickly. There is also BLM land 20 minutes from the lake where you camp disperse camp for free.
There are toilets, and showers available at the campsite. Dogs, fishing, and boats are allowed. Along the backside of the lake are the best spots if your looking to let your dog off of the leash to play in the water, or be secluded in the soft grass and shade of the bushes.
This is a nice family spot to spend the weekend. It gets very crowded very fast so be sure to leave early if you want to stay at one of the lakeside campgrounds. All roads are paved.
Sand Hollow is a beautiful man made lake with bright red sand and clear waters. This park allows for motorized and non motorized boats, off road vehicles, rentals, camping and dogs.
There are very limited spots by the water to camp, and fires are only allowed in specific fire rings. Outside firewood is not allowed. There is also an entrance fee to enter the park, National Park Passes will not work here.
There are nice day use areas, and areas designated for camping. Tents and RVs allowed, although most access roads are covered in thick sand. I would not recommend taking a low clearance vehicle. There is also a small restaurant for food and vault toilets for use.
You cannot camp around the entire lake. The back portion is fenced off, only allowing half of the lake to be occupied. I chose to camp as far away from the other campers by the backside of the lake. It was a very beautiful, sandy spot right by the water. However, it seemed like the other people staying at the park had no sense of respect or personal space. We set our tent up around 2:00pm and we constantly had ATV's, families with dogs off of the leash, fishermen etc walking/driving right through our site. This continued even through the night until quiet hours. Light and sound travel very well over this lake, so someone drunkenly singing with their buddies across the lake sounds like they are right next to you. People are driving their cars at all sorts of hours blinding you with the reflection off of the water. There are Park Rangers that drive around but don't seem to do anything. There was litter everywhere hidden in the sand. There are a couple of trees and bushes that provide some shade but I would recommend bringing a shade tent. There are also a couple of metal tables with attached chairs at some campsite locations.
This would be a beautiful location to visit for the day with your family. I would not recommend camping here overnight unless you don't enjoy personal space, respectful neighbors, quiet hours or humming RVs.
