No separate dump station available at RV park. Echo Bay or Valley of Fire is the closest to dump at.
Probably not at Fun 'n Sun, but you can dump at Valkey of Fire State Park by paying the $10 park entrance fee then going to the Dump Station. Or you can camp in the RV campground with water and electrictricity for $30 a night with entry fee and dump included.
I checked last year and they said no. I have heard that if you pay to camp at the Valley of Fire State Park there is a dump station there.
