All-4-Fun Facebook Happenings

The money collected for these permits goes to the Colorado OHV Grant Fund. In 2016 over $4,000,000 in grants were awarded using this money to fund trail maintenance, construction, trail heads, parking areas, trail signs, maps, and land acquisition. It also enables law enforcement personnel to identify and return stolen vehicles, encourages safe and responsible OHV use, and promotes respect for public lands.

Why We're Different

All-4-Fun moves to a new location every year. Locations include places like Buena Vista, Empire, Leadville, Salida and other great towns. There is a registration fee per vehicle, and all participants must be listed on the registration. Plenty of food, drinks and fun occur every year and there is always entertainment to keep you busy.

Last year we celebrated of 50 years of All-4-Fun all over Colorado, check out our History page for some fun and interesting information!

Group trips are available through Colorado's rugged mountains with as many as 10-15 groups leaving camp each of the 5 trip days of the event for excursions in the area mountains. Some trips will test your skills as a driver and put your rig through its paces. Other trips can leave you speechless as you view the stunning scenery that the Rocky Mountains provide in our great state.

Drive at Your Level

The event offers 4-wheeling options suitable to all levels of driver and vehicle. From stock to buggy, scenic to extreme, you can customize your experience at All-4-Fun. Our groups are much smaller than other events, providing more driving, less waiting and more fun!

Camping & Lodging

There will be a place to camp included in the price of your All-4-Fun registration*. If you are planning on attending the event, but you do not plan on camping at the All-4-Fun "Base Camp", there are other lodging options available in the Leadville area.
