Riding Your Horse on OSMP
Open Space and Mountain Parks offers many wonderful places to ride.
Many of our trails are open to equestrians with a wide variety of terrain, ecological sites and locations to fit the needs and desires of any rider. Some of our trailhead parking areas have been refurbished to include designated parking spaces for trailers. As we plan renovations to other parking areas, improvements for equestrian trailer parking will be considered.
We all enjoy OSMP in different ways. Expect to encounter other visitors on trails. Be courteous and share the trail so that everyone can have an enjoyable experience.
Before You Ride
- Review the Interactive Horse Regulations Map, which shows trails horses are allowed on and trail closures.
- Please check trailhead regulations or the OSMP website before your ride to familiarize yourself with rules & regulations or any temporary closures or reports of trail conditions.
- Feeding horses weed-free hay or feed prior to your visit is very important to help limit the spread of weedy invasive plants that can be difficult to manage and negatively impact native plants and wildlife habitat.
- Please leave dogs at home when riding. While some trails do allow dogs to be off-leash under voice and sight control, you must still be able to put your dog on leash at any time. Additionally, some seasonal leash restrictions or temporary leash restrictions may be put in place to protect wildlife like ground nesting birds and bears.
- When parking, try to economize your use of space and leave room for other trailers.
- Be aware of Habitat Conservation Areas (HCAs). Off-trail travel on horse back and on foot requires a special self-service Off-Trail Permit. Off trail horse back riding is specifically prohibited in the Eldorado Mountain HCA.
- Be safe! Some trails are very steep, rocky and difficult to ride. We encourage the use of helmets and taking cell phones along to call 911 for help.
When You Ride
- Trails and vegetation can be very prone to erosion and damage when conditions are muddy and wet. Please avoid riding during these conditions. If you encounter muddy areas, ride through the mud rather than around.
- Off-trail riding is allowed in most areas, but we ask you to refrain. Sticking to designated trails helps protect fragile habitats from resource damage and erosion.
- Anticipate other trail users around corners and blind spots.
- OSMP regulations require all other visitors to yield to equestrians. In practice, it may sometimes be more feasible for you to yield.
- Please be aware of other visitors’ comfort level around your horse, some people may be afraid of or drawn to your horse. Please be sensitive and communicate with other visitors.
- Please leave parking areas clean after your visit. Do not leave hay or manure behind.
- Marshall Mesa is the only trailhead with available water. Natural water sources such as streams may be present seasonally along some trails. Streamside areas are fragile so please minimize damage when approaching them.
