The Island Park Road is an 18 mile (29 km) unpaved road that leads to Rainbow Park and Island Park. The road starts outside of Dinosaur National Monument and ends inside the park near the Ruple Ranch Site. High-clearance vehicles are strongly recommended. The road is typically impassable when wet and during the winter.

The first 10 miles (16 km) of Island Park Road are outside of the park, winding through a mix of public and state land. Upon crossing the park boundary, the last 8 miles (13 km) reveal beautiful petroglyph panels at McKee Spring and stellar views of the Green River from Island Park. At Rainbow Park, visitors can enjoy a secluded tents-only campground near a boat ramp where river rafters launch boats for one-day rafting trips.

Driving Conditions

All 18 miles (29 km) of the Island Park Road are unpaved, but suitable for most high-clearance vehicles. All-wheel and 4-wheel-drive vehicles are great to have, but not strictly necessary for Island Park Road. The road does not change much in elevation.

Pets

Leashed pets are allowed on all roads, overlooks, campgrounds, and picnic areas. Pets are not allowed on the Island Park Trail. Handlers must clean up after pets.

Fees

Visitors must pay the park entrance fee or show a valid pass at the Entrance Station or Visitor Center.
