Bridges of Buck Gully Hike

Hiking & Fitness
Bridges of Buck Gully Hike

Be inspired by both the natural beauty and recent history of Newport Beach’s Buck Gully Reserve, as we explore this protected area and the collaboration that made it possible. Buck Gully is a natural coastal canyon that opened to the public in 2012 with the installation of four bridges to provide safe public access. The bridges allow exploration of the entire Buck Gully Reserve, and also provide unique vantages and viewing platforms from which to pause and observe the abundant life in and around the stream that runs through the gully year-round. Our guided program starts with a short walk from the Oasis Senior Center to the beginning of the Buck Gully trail, with a visually dramatic entrance into this special canyon. We’ll cross two bridges on the first section of our walk, and then enter the canopied singletrack portion of the trail as we pass by the third bridge. At the fourth and last bridge, we will pause to enjoy the shaded beauty of this hidden refuge, and then retrace our route back to the Oasis.
