RCMBA works to build healthy and strong communities in Humboldt County by promoting sustainable trail use and access for off-road cyclists through trail building and events.  We also help to maintain trails that mountain bikers and other user groups use and promote riding for people of all ages.



 We are always working on more access to trails in the Humboldt region, but we also host work days throughout the year and focus on different trail systems each time.  They are usually on Saturdays once a month or every other month, and are posted on our Facebook page and also on our website calendar. Come out to the next one, they are a blast!

We have been maintaining Lack Creek BLM trail system for the past few years, and we spend a lot of time in the summer getting those trails dialed for the annual enduro race, Stormy Saddle Enduro, which is usually on the last weekend of July. 

GREEN DIAMOND RESOURCE COMPANY AGREEMENT: We are super excited to be partnering with Green Diamond Resource Company, a family owned timber company in Northern California and Oregon. As of October 18, 2017, we got approval for our proposed route in Blue Lake on GDRCo land!! This is very exciting for both parties involved and is a project we have been working on for over a year.  The trails are near the fish hatchery and within riding distance from Mad River Brewery. Wahoo! All members who want to ride these trails must read and be familiar with the agreement between RCMBA and GDRC.



Our partners play a crucial role in our growing bike community on the north coast. We are lucky to have the following partners to collaborate with!
