Frequently Asked Questions

What is the terrain like on the Left Hand OHV Trails?

The terrain varies significantly. While some sections are relatively flat and easy, much of the area features uneven ground, small hills, and intermediate trails with steep sections, rocks, and roots. More difficult trails involve tricky, steep terrain, rocky ledges, and extreme obstacles, making them challenging for beginners. Hikers may encounter narrow and steep paths, with some uphill sections requiring extra effort.

Are the Left Hand OHV Trails suitable for beginners?

While there are some easier, flatter sections, many parts of the Left Hand OHV Trails are considered difficult due to steep inclines, rocky terrain, and challenging obstacles. Beginners should research specific trail segments carefully or consider the distinct 'Left Hand Trail' (associated with the City of Boulder), which is generally easier but can be very muddy after rain or snow.

What kind of scenery can I expect along the route?

You can expect scenic mountain views, including panoramas of Boulder and its peaks. There are also views along creek channels, and the area offers 'beautiful sunsets'. The landscape features wild sage, cacti, and you might hear chirping prairie dogs. Be aware that many trails in the area offer a general lack of shade.

Where can I park to access the Left Hand OHV Trails?

Parking is available at the Lefthand Trailhead. Facilities are limited, often only a port-o-potty in the summer. The area can get crowded on weekends, so arriving early is recommended to secure a spot.

Are dogs allowed on the Left Hand OHV Trails?

Yes, dogs are generally allowed on the trails. However, as this area is within Roosevelt National Forest, it's always best to check current regulations regarding leash laws and pet waste management. Always practice Leave No Trace principles.

Do I need a permit or pay an entrance fee to hike here?

As the Left Hand OHV Trails are located within Roosevelt National Forest, there are typically no entrance fees required for day use. However, specific activities or designated areas might require permits. It's always a good idea to check the official USDA Forest Service website for the latest regulations before your visit.

What is the best time of year to hike the Left Hand OHV Trails?

The trails can be enjoyed in various seasons, but spring and fall generally offer the most pleasant hiking conditions with milder temperatures. Summer can be hot with a lack of shade, and winter hiking is possible but requires appropriate gear for snow and ice. Be aware that trails can become very muddy after rain or snow, potentially leading to closures.

Does the trail intersect other well-known paths?

Yes, the route also passes through sections of the Left Hand Main Trail, The Grind, GZA, and Upper Creek Road.

What should I know about hiking in Roosevelt National Forest?

When hiking in Roosevelt National Forest, it's important to follow Leave No Trace principles, stay on marked trails, and be aware of wildlife. While there are generally no entrance fees for day use, always check for specific regulations or fire restrictions. Carry enough water, as sources may be limited, and be prepared for changing weather conditions, especially at higher elevations.

Are there any specific challenging sections to be aware of?

Yes, specific trails like 'Fireman Hill' are known for challenging terrain and great views, while 'Indiana Jones Trail' is considered 'rowdy'. Many sections feature steep rocky ledges, extreme obstacles, and very steep, hazardous parts, particularly on trails that were formerly used by OHVs. Be prepared for demanding uphill sections.

Is public transportation available to reach the trailheads?

Public transportation options directly to the Left Hand OHV Trails trailheads are very limited. It is generally recommended to access the area by personal vehicle. You may find some regional bus services to Boulder, but onward travel to the trailheads would likely require a taxi or ride-share service.
