Nestled at the foot of some mountains in Fountain Hills, Eagle View RV Resort is the nicest RV park in the Phoenix area without an age restriction.
Nice flat and level spots, friendly and helpful staff, and tons of amenities.
Amenities: fenced-in dog park, gym, laundry, pool and hot tub, tennis and b-ball courts, horse shoe pits, and a club house with a business center. Serve complimentary coffee and donuts in the mornings.
The only downside is the distance to Scottsdale and Chandler. Leave yourself 30-45 minutes to get into those towns (depending on traffic).
Great park!
