Description: The Portal Trail is a dangerous and overly confident bikers die.
Driving Directions:
From the middle of Moab, drive north on US-191 for 4.2 miles, turning left (west) onto U-279. After another 6.2 miles (10.4 miles from Moab's center street), turn right on a short dirt road with a sign that says "Dinosaur Tracks." The trailhead is at GPS N 38° 31.917' W 109° 36.473'.
Biking Directions:
After you've finished your 1000 vertical, you'll be grinding up one sandstone dome after another.
You'll navigate a path past the towering Wingate sandstone cliffs along the Colorado, up onto the domes and bowls of Navajo sandstone of the mesa.
At the top of the mesa, slickrock sections are scattered between short sections of sand that are rideable, but will suck the life out of your legs. Watch for the fork where the Golden Spike Trail separates from the Poison Spider trail at GPS N 38° 33.728' W 109° 35.800'. Make sure you follow the little jeeps, not the spikes.
  The Portal Trail heads back south (to your right) when you reach the viewpoint overlooking Moab at GPS N 38° 35.033' W 109° 35.688'.
  The Portal Trail starts as a narrow single-track, edging ever-closer to the vertical cliffs above the Colorado River. After clearing the cliffs, it drops 1000 feet in around a mile, with narrow squeezes, ledge drops, loose rock, and insane turns. When you hit the paved road, go west downriver a couple of miles to your starting point.
