Venue Description:

This is a great place along the Arroyo Seco that has been hiked for decades, not a bad way to start a Saturday morning. Trail is wide, but will narrow to single file trail as we get close to the waterfall. Will start right next to JPL and walk along the back side of it. Then we will continue through the valley till we reach a campsite for a small break. From there we will head straight to the waterfall, hang out for a few minutes then work our way back on the same trail to the parking area.
