One of my all time favorites
Lees Ferry Campground 54 designated sites. No hookups. RV dump station. Grills provided, no open fires. Quiet time 10 pm-6 am. Modern bathroom/comfort station. Potable water available. Launch ramp within 2 miles. Gas and supply store at Marble Canyon, about 5 miles away. No reservations. $20 per site per night.
Spend your days fishing, boating, or rafting, and spend your nights camping at Lee's Ferry Campground on the banks of the Colorado River.
