Chico Outdoor Adventurer Biking State & Regional Parks

Guardian and Annie Bidwell Trail Loop

With the loop being either all uphill or all down­hill, the Guardian and Annie Bid­well Trail (for­mer­ly known as the South Rim) is rec­om­mend­ed for advanced rid­ers in great shape.

Guardian Trail is an extreme­ly exposed sin­gle-track, fea­tur­ing cliff edges in some areas and amaz­ing views of the gorge. 

Annie Bid­well Trail (South Rim) Trail is extreme­ly rocky and very tech­ni­cal, with sev­er­al drop-offs of more than 4 feet along a washout. Start down a steep fire road at 10 Mile House Trail, take the left turnoff to ride down Guardian Trail. 

When Guardian Trail ends at South Rim Trail, bear right (north) for a steep descent to the Annie Bid­well Trail. Keep right for the Ten Mile House Road and back to where you began.
