This is an intense climb that does not have many sections to regain your oxygen. As such, it's a good training option that leads to a great viewpoint from Zanja Peak at the top with the option to connect to many other trails.
The trail starts at the base of the soccer complex road/parking lot. Start at the pavement and go left on the first dirt trail entrance. From there, you'll see the marker where this trail begins.
At any fork on the way up, stay right. Dig your way up and enjoy the view. The going is sustained, but the many switchbacks ensure that the grades don't get too steep to manage. Be aware that the route is mostly in the sun, which means that you'll be hot in the summer.
From the top of Zanja, take in the views as you catch your breath before starting the descent back the way you came. Overall, this trail is an easily-accessible option to get a great workout in with rewarding views.
History & Background
There was once an old dump site at the base of hill, which is why it's named "Dump Trail", but don't let the name deter you! Views from the top are lovely.
