Guadalasca to Backbone

Heading back towards the ocean along the northern ridge of Sycamore, the grueling uphill turns into a fun, fast singletrack connecting the top of Guadalasca, passing the top of Hell Hill, and links you up with the Overlook Fire Road; take this either back down to the Sycamore Fire Road...OR you can swing to the left after passing the sign for Hell Hill and take Backbone, which is far more enjoyable.
