Sugar-Hood Shuttle: Sugarloaf / Pythian Rd (spring & fall) @ Sugarloaf Ridge State Park
Apr 11 @ 9:00 am – 12:00 pm

Want to do a through hike from Sugarloaf to Hood Mountain or vice versa? Ride the Sugar-Hood Shuttle.

How it works
Every half hour our Shuttle will leave from either Sugarloaf Ridge State Park or Hood Mountain Regional Park’s Pythian Rd parking lot. Make a reservation and then ride to the other end of the trail, or hike and ride back. Riding first and hiking back to your car is the easiest way – no worries about how long you take to finish your adventure. No charge for the ride, but the suggested donation of $10 helps keep us going. Dogs are not allowed on the shuttle or the State Park portion of the trail.

——–CHECK OUR TIMETABLES HERE———
https://sugarloafpark.org/events/sugar-shuttle-2020/

We recommend a reservation, but you can ride on a space available basis as well.

The hike should take 3½ to 4½ hours.

Map: https://www.sonomaecologycenter.org/wp-content/uploads/2018/03/Shuttle_Sugarloaf_HoodMtn_Map.pdf

The distance is about 7.4 miles with approximately 2300 foot vertical climb.

Suggested donation of $10. Register at: https://sugarshuttle2020hm-py.bpt.me/

Shuttle operated by Team Sugarloaf / Sonoma Ecology Center in partnership with Sonoma County Regional Parks
