The trailhead is reached off of highway 261, which runs from near Natural Bridges south to near Mexican Hat. From the north (highway 95/261 junction) go south about 8.5 miles to mile post 24.1 and 24.1 miles north of the junction with highway 163 if coming from the south.

Walk the old road 0.3 miles to where it end. From the end of the old road, follow the social/cow trail as it follows the south (left) side of the drainage. In 5 minutes, it crosses over to the right to avoid a dryfall. Yellow House ruin is at the bottom of this dryfall, and can't be missed from the trail. It is a good ruin, complete with grass lashings.

Continuing down, follow the social trail. A small wall is visible on the right, but not worth the side trip. Not far below Yellow House, the trail passes a good granary just above the stream level. Continue down, keeping an eye on the right for a couple of walls of a very poor granary far on the right.

That is it for ruins until near the junction with Grand Gulch. Follow the stream bed down. As it begins quickly dropping and deepening, route find around the first obstacle on the left or right, then the rest of the boulder fields are passed via a social trail on the right.

Once through the boulders, the canyon levels out with a good spring. Green Mask ruin is easily visible here on the right, a few minutes up from Grand Gulch. (about 2 hours to here.) If your struggling to find the Green Mask, look up! It is high on the east side, near the spring with a large panel.

If not doing the loop with Bullet, wandering up or down Grand Gulch before returning is recommended. Down, in particular, has some good ruins within a mile or so.
