The road south creates a nice, fast, gradual descent from the north side of Altadena. Just be safe and keep an eye out for cross-traffic at the intersections.

Climb out of the Brookside Golf Club area and into the Pasadena suburban area. This climb has a nice shoulder and is lined with trees.

The Club House is a vibrant bike shop offering bike sales and service, apparel, gear, and cacti. What began with a red VW bus and online sales in 2017 transitioned to an old service station turned plant store. A small, fun-loving team runs the shop, sharing their love of cycling. Stop by for events like the annual Bike & Car Show, a lazy Sunday ride, the Wednesday night Basket Ride, or just to grab coffee at their mobile espresso bar.

Chantrey Flats is the natural end for those riding the Sturtevant Trail. If you shuttled to Mt. Wilson with a friend then this is likely the end of the line for you. Others might need to ride back down to Altadena if they took the shuttle offered by SCOAoutdoors.net. And still others might be climbing their way back up to the top via the myriad of roads and trails that depart from this picnic area.
