Saw no snakes
Snake River Area Campground near Valentine, NE is on the Merritt Reservoir State Recreation Area.
Can you say sand! And fishing. The nice thing about this entire area is one: you don’t see much of the park employees, it’s pretty much all honor system based. Which means if you occupy an entire campground you can stay up as late or early as you want. You can also be as loud or quiet as you like too. Two: This is definitely a water based vacation. The reservoir offers plenty to do and the campground is shaded and did I mention sandy. Dark at night, like pitch black. Critters are around so secure your food. Picnic tables, pit toilets, fire pits and a trash receptacle.
There is the Niobrara River nearby which is the major attraction of the area for float trips. Valentine, NE has food and fuel plus events throughout the year.
