Visitors to the Rainbow Park and Island Park area, located on the Utah side of the monument approximately 30 miles (48 km) from the Quarry Visitor Center, can discover some of Dinosaur's most scenic geology, watch river rafters float past the Green River (or, with a little advance planning, be one of those river rafters), and explore petroglyphs and a historic ranch, both part of the monument's long human history. Picnicking and camping are also available in the area.

Visiting the areas described below requires driving on unpaved roads. These roads are impassable when wet. Before heading to the Rainbow Park and Island Park area, stop at the visitor center for information on road conditions.

Petroglyphs at McKee Springs



The Fremont people, who lived in this area approximately a thousand years ago, left evidence of their presence in petroglyphs (patterns chipped or carved into the rock) and pictographs (patterns painted on the rock).

Petroglyph panels at McKee Springs include some of the finest large human-like designs in the Dinosaur area, as well as many other figures. The petroglyphs are a short walk from the roadside pullout.

Ruple Ranch
In 1882, Henry and May Ruple began homesteading in Island Park and developed a cattle ranch. The Ruples' son, Hod, took over the property in 1915. Later, Hod Ruple and his family switched from cattle ranching to sheep ranching. The property remained in the Ruple family until 1945.

Although the family's original house burned in 1960, the corrals and loafing shed found on the site today were used in the Ruples' ranching operations.

River Rafting
One-day raft trips depart from Rainbow Park. On these trips, rafters enjoy a 9-mile (14.5-km) trip along the Green River, passing through Class I-III rapids and the colorful canyon walls that rise 1,500 feet above the river.

Raft trips must be arranged in advance. Learn more here.

There are no established short trails in the Rainbow Park and Island Park areas. The open country invites exploration along the Green River and around the Rainbow Park Campground. Visitors who want to travel cross country into more remote areas should carry a map and compass and have the ability to use them. You should also be prepared with plenty of water and gear appropriate for the weather conditions.

The Island Park Trail is a rugged hike that leaves from near Ruple Ranch and traverses remote country until it reaches the Jones Hole Trail. This trail is not routinely maintained. It can be difficult to follow in some areas and can require route finding skills. It is approximately 8 miles one way to the junction with the Jones Hole Trail at Ely Creek..
