Location for Merritt Reservoir is 26 miles southwest of Valentine on Highway 97. Or 47 miles north of Mullen on Highway 97.
This place is absolutely beautiful. The night sky is breathtaking. I've never seen so many stars before. If you're a "sky" person, you need to at least visit this area once in your life.
There are many campsites to choose from here. We stayed at the Cedar Bay campground and had an amazing overlook of the lake with a sandy beach. The water had a ton of algae in it when we were there so we couldn't go swimming.
There were two groups of extremely rude campers while we were there as well. There was a trailer full of drunk early 20s kids blasting music until 4:00AM. I woke up at 2AM to ask them to respect the quiet hours, but they were too wasted/oblivious to even understand it seems. If you're one of these people, please go camp and get wasted in your mom's backyard next time.
