Do have to make reservations to camp at moses lake n if so how much a nite

Camping is free at the sand dunes

No.

Yup! Free just be careful where you pull in so you don't get stuck in the sand. There's also an awesome guy who delivers pizza out there!. Oh! And make sure your ORV has lights and flags

Free but bring water and shade for sure
