    Skyline to the Sea Trail 

    This is a one of a kind opportunity to explore California's first State Park. The Waddell Creek trailhead is 5 miles south of Costanoa. This is 12 miles round trip designed for beginning to intermediate riders. Doublewide fire roads meander along Waddell Creek and eventually up to spectacular Berry Creek Falls. You can also add on a tour of the Rancho del Oso Nature Center.

    Gazos Creek Road 

    For those with a limited amount of time but want to see as much as possible and get some exercise as well. Start at Costanoa and take Old Highway 1 to the North where you can take in the windswept views of Franklin Point Beach. Gazos Creek Road then meanders east into a land of towering Redwoods and massive Ferns. Stop and break along the creek bed to cool your feet before the downhill leg back to Costanoa. This intermediate ride takes up to 2 hours. For those who want to add on some mileage you can add a lunch stop in Pescadero and then return to Costanoa via Highway 1 South passing by Historic Pigeon Point Lighthouse on the way.

    Butano Fire Roads 

    For the ambitious and experienced only! Warm up along 7 miles of country backroads before entering Butano State Park. Butano is home to a complex system of hidden fire roads that lead to exhilarating saddlebacks and unparalleled views of the surrounding State Parks. The final drop back into the Redwoods will challenge the most technically advanced riders. This is a half-day event geared for serious enthusiasts.
