The estimated duration for mountain biking this route is around 2 hours and 30 minutes. However, given its challenging nature and technical sections, your actual time may vary significantly based on skill level and how often you stop to enjoy the views or navigate difficult terrain.
No, this route is considered
difficult and is not suitable for beginners. Both Incinerator Ridge and Green Mountain Trail feature extremely challenging terrain, including loose, steep, rocky sections, tight switchbacks, drops, and potential hike-a-bike sections. Incinerator Ridge is even rated as a double black diamond trail.
The terrain is exceptionally challenging and varied. You'll encounter technical singletrack with loose, steep, and rocky sections, along with very tight switchbacks. Expect drops, considerable exposure, and even large fallen trees that may require climbing over. Some sections on Green Mountain Trail also include stairs and uphill pushes, making for a very demanding ride.
Access to these trails typically involves starting at higher elevations on Mt. Lemmon. Many riders utilize shuttle services, especially as these trails are often part of the longer, challenging 'Lemmon Drop' descent. Specific parking areas can vary depending on your chosen starting point for the full route, so it's advisable to research shuttle providers or common drop-off points for the 'Lemmon Drop' experience.
While there isn't typically a specific permit required for mountain biking on these trails within the Coronado National Forest, it's always a good idea to check the official U.S. Forest Service website for the Coronado National Forest for any current regulations, fire restrictions, or potential day-use fees that might apply to certain recreation sites or parking areas.
Regulations regarding dogs on trails within the Coronado National Forest can vary. Generally, dogs are allowed on many trails but must be kept on a leash. Given the extreme difficulty and technical nature of this particular route, it might not be the most suitable trail for all dogs, especially those not accustomed to very rugged terrain. Always ensure your dog is leashed and that you pack out any waste.
The best time to mountain bike this route on Mt. Lemmon is typically during the spring and fall months when temperatures are more moderate. Summer can be very hot, especially at lower elevations, while winter may bring snow and ice to the higher parts of the mountain, making the already difficult trails impassable or even more hazardous. Always check local weather and trail conditions before heading out.
You can expect fantastic and diverse views throughout the ride. The trails wind through the varied forestry of Mt. Lemmon, offering glimpses of bright green ferns and vast vistas. From various ridges, you'll be treated to expansive views of the San Pedro River valley and the Galiuro Mountains, making the challenging effort worthwhile.
Yes, this route is part of a larger network of trails on Mt. Lemmon. It includes sections of the
Arizona Trail Pusch Ridge Wilderness Bypass, the Lemmon Drop, and the Sky Islands Traverse. You'll also ride portions of the Incinerator Ridge Trail #18A, Green Mountain Trail #21, and the Kellog Trail #45, among others.
While the name suggests a loop, these two trails are often ridden together as part of longer, more extensive routes, rather than a single, defined 'loop' consisting solely of Green Mountain Trail and Incinerator Ridge. It's a significant segment of the epic 'Lemmon Drop' ride, which typically involves a shuttle to access the higher elevations.
Given the route's difficulty and remote nature, you should be well-prepared. Essential items include plenty of water, high-energy snacks, a repair kit for your bike (including spare tubes, pump, and tools), a first-aid kit, navigation tools (like a GPS device or a fully charged phone with offline maps), appropriate protective gear (helmet, gloves, knee/elbow pads), and layers of clothing suitable for changing mountain weather.
