This well-known swimming hole is located on Barton Creek about a mile upstream from Barton Springs. You can also get there by taking the Spyglass Road access point and turning left onto the trail once you reach the creek.
When the water level rises after a rain, this should be a good size pool, and there are other locations to try both upstream and downstream from this one. This place will be crowded in the afternoons, so be forewarned. There are also some nice bluffs in the area, though unlike in the past, houses now line the tops of the cliffs.
