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. Look for the trail at a break in the fence at the north corner.
From the north: As you head southbound, all trails will funnel into the Klondike Bluffs Road. After going through the sandy wash, you'll pass Jurassic on the left, then reach Inside Passage about 0.2 mile further on.
