"Volunteer for the Search and Rescue Team here, so I am in JTNP all the time. Recommendations or tips:
* Yes that first climbing bolt really is 30 feet off the ground---what can I say it is the local style of bolting. There is no shame in carrying a stick clip in this park.
* The guide book may say the climbing route is only 5.8, but after the 10,000th climber that just finished the route it is more like a 5.12, because now it has been polished by so many hands and feet pulling on it. The climbing is awesome, but don't let the easy ratings and rocks that are not that high trick you into doing something that you are not ready for.
* Great hike is Ryan Mtn and for off days take a tour of Keys Ranch.
