Mount Falcon and Lair O' the Bear loop

After the climb, expect road riding sections before transitioning to 'shout-out-loud' singletrack descents in Lair O' the Bear, which are predominantly flowy but also include some small climbs and enjoyable rock features. Many technical sections offer intermediate lines, allowing you to choose your challenge level.
