This trail is an awesome ride with an epic view at the top and lots of wildlife! The trail itself is mainly smooth fire road but it does get a little rockier towards the top.
Climb to the top, check out the view, and rest and then descend down what has to be one of the most fun and long "fire-road" downhills! It's not very challenging but it's got a lot of flow and lots of trees so it's very shaded.
Be courteous to everyone as it is a hiking trail, too. Note: there is some really good technical riding just off the main trail, just reverse the trail direction to get back.
*Snow rides here are EPIC, just be sure to call Mt Baldy Visitor Center
and check if Glendora Mt. Rd. is open!
