Traveling SW on the main park road (toward the Park
entrance), go about 0.6 mile past the turnout to the Park
Avenue parking area (the road makes a big loop here).
Look to the right (NE) and find Porthole Cave Arch near the
bottom of the formations. Then direct your gaze to the
north and locate Split Top Arch at the top of the formations.
Although light may not be visible through the opening, the arch
can be identified by comparing it with the photo.
