You can find Boca Cave by taking a short spur trail near the summit of Triangulation Peak. The cave offers some pretty cool views from the entrance and is actually a pretty wide shelter in itself once you start walking through it. If you've already gone up the slopes of Triangulation Peak, this is worth a visit.

The sidetrail to the falls is noticeable but not well marked. Watch for it. The trail down to the falls is fairly easy to follow, but it does get quite steep to get down to view the falls. Marion Falls was originally named Orla Falls by the young men of the scouting party who had danced with Orla Davenport, the oldest daughter of the surveyor. Gatch Falls (the lower one) was named after Prof T.M. Gatch who had taught all of these same young men.
