From the town of Overton, head south on NV-169 for about 9 miles to the entrance station at Lake Mead. About 0.1 miles past the entrance station, turn left onto the good, graded dirt road signed for St. Thomas. Follow the road 3.5 to it's end and the trailhead. Just before the end of the road is a junction, go right at the junction.

The park service labels this an unmaintained trail, but it is well-defined, easy to follow, and has informational signs, so I am not sure how unmaintained it is! From the trailhead, follow the trail as it descends to the lake bed and the first informational sign. One of the things we found interesting was all the seashells along the trail in this section. They are shells along most of the trail, but seem to be in higher concentration where the lake levels were relatively shallow for a long period of time.

Once down the small descent, the walking is flat. Follow the main trail. It is about 0.6 miles from the trailhead to the town. There are informational signs at the corner and the first major foundations are seen.

The old streets of the town are still somewhat visible. The most common path, and the one with informational signs, is to walk a loop, heading east and passing many old foundations, including the old grocery store.

At the east edge of town, the trail heads south, passing the largest foundation, that of the old school house. It then turns west, passing an old foundation that was once the general store, before looping back to where you entered the town.

There are additional unsigned foundations in the town, but I think the signs make the history come alive. Return the same way once the loop is complete and you have finished wandering the town.
