Directions to Swett Canyon Trailhead:
From Hanksville, Utah follow highway 95 Southeast for 25 miles and turn right (south) on highway 276 toward Ticaboo and Bullfrog Marina. At 13.8 miles down highway 276 there will be a shallow canyon that crosses beneath the road. This is upper Swett Canyon and you'll want to park in the small pullout on the left side of the road, just before (north of) the canyon. If you see mile marker 14 (somewhat hidden on the right side of the road), you've gone too far.
From the car you just drop down the highway enbankment that leads to the canyon and your on your way.
