Chiquito Trail is typically a shuttle because you're dropped onto Ortega Highway. You can shuttle down from Blue Jay Campground, or climb Old San Juan Trail
to New San Juan Trail
. Climbing SJT and completing the Chiquito Trail is doable, but very challenging.
The trail has some technical features that can only be ridden by very advanced riders but are short and easily walked over. Built-up features exist throughout the trail, but they are tastefully built to integrate with the surroundings, so if you want to ride them, you have to look for them.
There's a long climb at the end, so keep some gas in the tank to keep from bonking at the end. This is especially the case if you rode up SJT.
