Jurassic Trail -- Loop via EKG
The Jurassic Trail is a smooth singletrack on the west side of the Klondike Bluffs riding area. There's very little elevation change over the ride, as it skirts the edge of the mesa to the west of the Copper Ridge road. The trail is suitable for beginners. There's little elevation change on the trail. There are no stiff climbs and nothing tricky. This page describes a loop that will satisfy advanced riders, using the west-side singletrack southbound and EKG northbound.

Getting there, Agate Northern Klondike TH: On Highway 191 8.5 miles south of I-70 and 6.5 miles north of the southern Klondike Bluffs road (and about 5 miles north of the airport), watch for a "Northern Klondike" sign at N38 49.504 W109 46.893. Turn east (toward the sandstone bluff). Keep to the right as the road winds south around a small hill. 1.2 miles from the highway as the road is heading east toward the bluff, fork right on a fainter jeep road N38 49.103 W109 46.061, as the main road continues to the dinosaur tracks. (Park here if the road is in bad shape.) At mile 1.6, you'll come to the TH for the Jasper and Agate loops (N38 49.087 W109 45.625) on your right. (If you continuye on, you'll arrive at a larger parking area N38 49.179 W109 45.417 at the bottom of Mega Steps.)

Getting there, Klondike TH: Starting at the Colorado River, drive 15 miles north from Moab. Look for a turnout with parking on the right and a sign for Klondike Bluffs Road. There will usually be cars parked there (GPS N 38° 44.452' W 109° 44.037'). For a longer ride, park here and ride up the road.  Most cyclists will choose to go through the gate and drive 2.7 miles. Keep left at the fork. At 2.8 miles, park your car in the broad parking area by the fence. Go eastbound across the cattleguard for the Klondike trail, or find the singletrack Inside Passage at the north corner of the fence.
