After you reach the curtesy dock, there is a 1.5-mile trail to the observation area. NOTE: as water levels change, so does the length of the trail.
Rainbow Bridge is only accessible by boat or by land over a 14 mile trail. Visitors may take their personal boats to Rainbow Bridge. Boat tours to the Bridge are available from Aramark and Antelope Point, the park's concessioners. Once you dock your boat there is a 1.5-mile trail to the Rainbow Bridge obervation area.
If you choose to backpack to Rainbow Bridge, a permit must be obtained from the Navajo Nation.
