We hiked the shorter trail, Leroy Smith nature trail. The longer one is called JFA, Jorge Francisco Arango, and is a little over 5 miles. Even just the shorter trail was nice with plenty to see and enjoy. I didn't seem to find a short trail called Sassy's Pass.
Getting back into this and this is a great beginner / intermediate trail. Just about ready to take on something tougher. If you're out of shape, this is still entirely doable, and a great workout. Either way, it's a really fun ride.
