Eden Falls is sourced from a cave directly above the falls. You will see the hike up the falls progress in the videos until Kayleigh, my Labrador Retriever, and I enter the cave. The National Park service is currently working to make the trails more accessible for more people (the joy of stimulus money no doubt), and part of the trail to the Natural Arch and falls was roped off for construction. Luckily, I met the park rangers working on the trails and they encouraged me to go into the area after they were done working.
Here's videos and pictures of the hike into the Lost Valley, which is located just a couple miles outside of Ponca, Arkansas.
