There are lots of trails off the main loop; some are steep and some are moderate to easy. Unfortunately the most scenic parts, which includes unique rock formations and an arched wooden bridge, runs along the road and the sound of the cars ruins the experience.
This is a nice short hike. Whole loop takes me about an hour Maybe an hour 10. I like to use this trail to work on my cardio for peak bagging. There is some long and steep terrain. Up and down the hillside. I don't like that it runs right along 22. You always can hear the cars.
