Trail Running on the Ninja Loop

Rate this Adventure San Francisco Coastal Trail (Ninja Loop)

Added by molly haight

This is a fun trail run that's easy to get to from the city and not too technical. You'll have awesome views of San Francisco, the Golden Gate Bridge and the Pacific Ocean. The uphills are challenging but you can look forward to fast and fun descents.

This loop can start from several different locations, including Rodeo Beach and the Golden Gate Bridge parking lot. Starting from the GGB will add 2 more miles onto this run. I like to start at the Coastal Trailhead parking lot off of McCullough and Conzelman Roads (just a notch down from Hawk Hill).

From here Coastal gradually descends for about a mile, cross over the road at the bottom to get to Rodeo Valley Trail. Stay left on Rodeo Valley until you reach a fork and then keep left towards Miwok.

Miwok is the first of two major hills. Miwok winds upward for about a mile and a half, it's a steady and challenging climb but do not forget to look around and enjoy the view! Towards the top keep a steady eye for Old Springs Trail. Turn left onto Old Springs Trail and enjoy a long but fun downhill into Tennessee Valley.

Take a sharp right after the horse stables onto Marincello. Marincello is a long steady climb but the last major part of this run, be sure to preserve your energy because just when you think this climb is over, it won't be.

Stick with Marincello for about three miles, when you get to the top it ends. Be sure to go straight onto the SCA trail. The SCA trail is a short winding trail leading you back towards the parking lot with great views of the city and the Golden Gate Bridge along the way. Follow it until it connects back to Coastal and have fun bombing one last steep descent before you are back at your car.

There is no tree coverage on these trails and on a sunny day it can get very hot so make sure you are prepared. Although beautiful and rewarding, this is a challenging run.
