Our mission as an All-Terrain Vehicle (ATV) non-profit organization is to unite Off-Highway Vehicle (OHV) enthusiasts and supporters in an environmentally friendly atmosphere by promoting an attitude of public service, volunteerism, and safe responsible OHV riding practices, “While Using Not Abusing Our Public Lands”.  We partner with Public Land Managers and other interested groups to encourage and practice the development and implementation of environmentally responsible methods for the construction, re-construction, preservation and maintenance of ATV/UTV/OHV trails and full-size vehicle 4X4 roads on the Western Slope of the State of Colorado.  We are strong advocates of the “Multiple Use” management philosophy of our Public Lands.


Thunder Mountain Wheelers (TMW) of Delta Co. has for over 20 years been a partner with the federal agencies and the State in promoting opportunities for the use of trails for OHV’s 50” inches or less riding community. TMW members have actively participated in the development and implementation of many travel management plans, RMP’s, map development, installation and maintenance of trails, installations of signing and generally participating in the process to enhance and protect our <50” riding opportunities. Thunder Mountain Wheelers has literally contributed through the CPW grant process over $1.8 million dollars toward the sustainability and management of <50” or less trails.

Utilizing OHV grants from CPW along with grants from Polaris and Yamaha, TMW has adopted and maintained many trails and lakes on Colorado’s Grand Mesa, Uncompahgre and Gunnison National Forests which in turn makes for a memorable experience for all who enjoy our public lands.

Established on July 26, 1990, The Thunder Mountain Wheelers (TMW) ATV club of Delta, CO boasts of membership of over 150 members and growing. We are a tax-exempt 501c(4) Colorado nonprofit corporation.


We believe in having fun riding while promoting safe and responsible use. We are very active in preserving the privilege of riding on public lands by being involved in land use issues with the Federal Land Management Agencies.

Guest speakers are often invited that offer expert advice and information on a wide variety of topics.

Join us for the next meeting at the Delta Trap club (1670 I Road) in Delta, CO. Enjoy a potluck dinner with brats, hamburgers and drinks. We ask each member to bring a covered dish or dessert to share along with their own dinner service. Visit with old friends and meet some new ones. After dinner stay for that months agenda and guest speaker discussion.

We sponsor two+ rides each month from April through October. Most rides are from 20 to 40 miles long and take the majority of the day. Lots of water and a lunch are recommended. Rides are at leisurely pace with many thumb breaks along the way. Sometimes a history lesson of the area is given by one of the “old timers”. No one is expected to ride beyond his or her ability. In case of an emergency, a fully stocked commercial first-aid kit accompanies each ride. Helmets are not mandatory, but are strongly recommended.


We have adopted many trails and lakes on the Grand Mesa, Uncompahgre, and Gunnison National Forests. We have received numerous Colorado State Parks OHV grant funds to maintain our adopted trails including the purchase of Sweco 480 trail dozers specifically designed for maintaining ATV trails. This dozer is used the entire summer season to protect the resources with trail maintenance; re-construction and restoration keeping the ATV trails in tiptop shape.


Come out and see what we’re all about. Join us at our next meeting, sign up, go for a ride or help preserve your favorite trail. You can make a difference, meet some new friends and enjoy the great outdoors.
