Since 2020, Palm Canyon Trail—a multi-use trail—has seen a significant increase in users: hikers, equestrian and mountain bikers, including eBikes. Most of the trail crosses BLM and US Forest Service land. The Trail crosses private land as well as land owned by Agua Caliente. The properties the Tribe recently received as ancestral land back donations were offered to the Tribe. As a property owner with the right to regulate access to its land, the Agua Caliente chose to improve a portion of Palm Canyon Trail that is on its land—not federal land. The Tribe conducted trail maintenance work within its own property in the Indian Canyons for emergency access, security and safety for our hikers and other lawful users of the Trail. Why did it do this? Because it values its lands and prioritizes proper management of it. Unfortunately, one entitled business owner, [Dave Wood, owner of Bikes and Brews -tgk] who is unhappy over the fact that mountain biking and e-mountain biking is not allowed in this area is acting out by spreading false information, which is unnecessarily causing confusion in the community. His false narrative insultingly prioritizes his desire to financially profit from trespassing on Tribal lands, over the Tribe’s right to protect its property and its cultural resources. Tribal employees are now receiving “anonymous” threats promising more property destruction if tribal staff attempts to interfere with this illegal activity, which generates profits by organizing trail rides for groups of bikers who (unknowingly) trespass on a trail where that activity is not permitted. The Tribe has never permitted mountain biking on its land. The land acquired as land back donations is now Tribal land and consistent with our policy, mountain biking and eBikes are prohibited. Anyone on a mountain or eBike accessing the land is in trespass of Tribal lands. Trespassing on, and damaging, the property of another is never ok. We ask this business owner to ride his bicycle somewhere else where this activity is permitted.

The Palm Canyon Epic Trail is now closed to mountain biking. In April and June 2024 several landowners of wilderness areas donated their land to the Agua Caliente Band of Cahuilla Indicans (ACBCI). The donated lands included important parts of the Palm Canyon Epic Trail. As part of ACBCI policy on land use, mountain bike travel is prohibited on these lands. Recently Margaret Park-Robinson, Chief Planning Officer of ACBCI released a statement concerning the closure of the PCE. She can be reached at 760-883-1326 or email: mpark@aguacaliente-nsn.gov I append the full statement to this comment. Tom Kohn ACBCI Statement on the PCE closure Since time immemorial, Agua Caliente and other Cahuilla have lived within the lands of the National Monument, including Palm Canyon. Since time immemorial, the Palm Canyon Trail has been a significant cultural and historical pathway for Cahuilla people. Since 2000, the National Monument was established despite concerns by Agua Caliente. The legislation directs the federal agencies (BLM & USFS) to consult with Agua Caliente. Since 2008, Palm Canyon and the portion of the trail was designated as a federal Wild & Scenic River by the US Forest Service despite concerns by Agua Caliente. continues in a following post...

With 10,883 feet, Mount San Jacinto is the highest peak in the San Jacinto Mountains. There is a network of hiking trails around the summit and the San Jacinto State Park itself. If the weather turns for the worst, you can find shelter in a little hut close to the summit. You can either take a hike from Idyllwild on the west side of the mountain or Palm Springs on the east side. There is also an aerial tramway you can use to get into the San Jacinto Wilderness. If you feel adventurous, you can cross the mountain range using the Pacific Crest Trail.

This structure sits on Tahquitz Peak, at an elevation of 8,846 feet. The fire lookout was built in 1937, and is the highest lookout tower in the San Bernardino National Forest. It is maned by volunteers!

This trail is suberb! Palm Canyon Trail is a true backcountry experience for experienced mountain bike riders. I recommend riding this trail between November and March when temperatures are still a bit cooler. Bring lots of water and don't forget to pack spare tubes.

Tahquitz Peak is a great hiking destination with picture postcard views to the southeast and the Salton Sea. It got its name from a Native American legend saying that a demon wanted to possess the area. When the demon was killed, the spirit escaped and is now living in a cave in the San Jacinto Wilderness. San Bernadino National Forest operates the seasonal fire lookout at the summit of Tahquitz Peak which is mainly staffed by volunteers and is also the highest within the National Forest. The trail up to the mountain can be very dangerous in winter conditions, so bring proper gear. You need to obtain a free of charge wilderness permit from the Ranger Station in Idyllwild or call (909) 382-2921.

Close to the suburbs of Los Angeles, the hike to Etiwanda Falls is short enough for a stroll, but takes away the stress of the big city. Especially on a hot day you will enjoy the shady canyon with the cool water besides the beautiful scenery. You can park your car at the North Etiwanda Preserve Parking Lot which is also the trailhead. The park opens at 6.30 a.m.
