I have been coming up to the White Mountains since I was a kid. Rainbow campground has been our go-to spot for camping. There are 3 loops that are FCFS. The rest of the sites are reservations. The sites all have picnic tables and fire rings. There are full bathrooms throughout the area and pay showers when is not covid. Big lake is a short drive from the campground, where you can rent a boat, fish from shore and a small store with supplies. There is always wildlife around, especially skunks, so watch your pets. The sites are laid at where you don't feel like you are right on top of your neighbor. None of the sites in Rainbow have hook-ups, bit there is a dump station down the road. There is another campground for full hook-ups down the way.
