Rainbow Basin Natural Area/Owl Canyon Campground

Here's what the site says: "Vehicle Touring
Within this Area of Critical Environmental Concern, routes are posted with "open" route markers. Use of passenger vehicles and four-wheel drive vehicles is permitted only on designated and signed open routes. Staging of off-highway vehicles (e.g. ATVs) is not allowed in the Rainbow Basin area or at Owl Canyon Campground.

The Fossil Canyon Loop Road is an interesting route for vehicle touring. Keep in mind that this one-way narrow dirt road is best driven with a high clearance or four-wheel drive vehicles.

FOSSIL CANYON LOOP ROAD IS NOT RECOMMENDED FOR PASSENGER VEHICLES AND SHOULD NEVER BE ATTEMPTED BY MOTORHOMES OR VEHICLES TOWING TRAILERS.

BROWN markers with route numbers or road names indicate an OPEN ROUTE for use by motorized vehicles.
RED markers indicate routes that have been CLOSED to all vehicle travel.
No marker indicates aCLOSED route. Within the Rainbow Basin area, travel is permitted only on designated OPEN routes."

Can't get to the area... The washboard road is too rough for anything other than four-wheel-drive vehicles... A jeep would be highly recommended, if you're going to venture out here.

is this an only SUV area?
