CALDERA

BIKEPACKING ROUTES

GRAND DEPART SEPT 20, 2024

TUFF DEPART SEPT 13, 2024



BACKGROUND:

The Caldera Bikepacking Route is a series of loops in the Pamidu Toiyabe starting and ending in Mammoth Lakes, California. There are currently 5 versions of the route: a 500-mile "full" loop, two 250-300 mile "half" loops (the full loop cut in half), and two 150-200 mile "mini" loops (skinnier versions of the half loops). 


The area you'll be biking through is unique in its biodiversity, ecosystem variety, elevation, and more. You'll ride through five different mountain ranges (Sierra Nevada, White Mountains, Inyo Mountains, Sweetwater Mountains, and Glass Mountains), and three distinct biomes (Sierra Nevada, Great Basin, and Mojave Desert). It is truly a tapestry disparate realities, all in one unsupported (or supported, up to you) go.

  • Responsibility

    You are responsible for you. Sheek Group LLC, dba Mammoth TUFF, is not responsible for your well-being during any attempts of these routes. This institution's guiding services and event promotion services operate under permit on the Inyo National Forest. However, the Caldera Collection is a separate entity with no permits required because we are simply housing the routes and information. The USDA Forest Service has granted us permission to manage these Caldera routes so long as no exchange of money takes place for registered riders. Good luck and be safe out there!

  • Pamidu Toiyabe

    This route passes through the public lands we know today as the Eastern Sierra.

    To the Nüümü (Paiute), Newe (Shoshone), Timbisha, and Washoe peoples who are and have been the original inhabitants and stewards of these lands since time immemorial, it is known as the Pamidu Toiyabe.
