At Merritt Reservoir State Recreation Area near Valentine, NE you have some choices to make. There are Merritt Main, Willow Cove , Lone Tree, Cottonwood , Pines, Cedar Bay , Beeds and Board Campgrounds to choose from. Each has sites near the Reservoir or further back in the scrub that have fire rings and picnic tables. Some have electric options, showers and boatramps. All have at least a pit toilet and dumpster. (And sand)
The state employees were a little scarce when I visited and the weather was not real inviting. I decided to not float on the Reservoir due to the low temperatures, but it would seem that the Nebraskans are a little hardier and used to the cold temperatures then me because there were a few out on the water fishing.
This area would be ideal for a large group get together and out in the middle of nowhere so any noise shouldn’t be an issue. I heard coyotes and it was pitch black at night, had the sky been clear the stars would have been amazing.
Valentine, NE is nearby for resupply and entertainment and there are some other recreation areas that offer hiking and of course floating on the Niobrara River.
