San Mateo Peak via Morgan, Tenaja Falls, and San Mateo Peak Trail Loop

This loop is rated as difficult due to its length (over 18 km) and significant elevation gain (over 650 meters). While some segments, like the San Mateo Peak Trail alone, are considered moderate, combining them into this full loop creates a challenging experience. Be prepared for strenuous sections, especially the steep climb to San Mateo Peak.

The terrain is diverse. You'll start with gentle, rolling chaparral hills, transition to an 'oasis-like' shaded section along a creek, and then ascend towards San Mateo Peak with picturesque granite outcrops. Expect potential creek crossings, especially near Tenaja Falls, which can be tricky during high water. Some areas might have overgrowth, and sections near Fisherman's Camp can involve rock hopping in dry riverbeds. Slippery rocks are common near Tenaja Falls, particularly when wet.

Hikers are treated to expansive views from the summit of San Mateo Peak, encompassing the San Mateo Canyon Wilderness, Mount Baldy Massif, Lake Elsinore, and distant mountains. Other notable points include the seasonal Morell Creek, Lion Spring, and the Morrell Canyon Boulder Overlook. Tenaja Falls is a significant highlight, offering a roaring cascade in wet seasons and framed by large boulders.

Spring is ideal for vibrant wildflower displays and when Tenaja Falls is most impressive, flowing as a roaring cascade. However, be aware that overgrowth can be more prevalent after a wet winter. During drier months, the falls may be reduced to a trickle. Due to significant sun exposure on much of the trail, cooler months or early morning starts are recommended during warmer periods.

Yes, trails within the Cleveland National Forest, including this loop in the San Mateo Canyon Wilderness, are generally dog-friendly. However, dogs must be kept on a leash at all times. Ensure your dog is prepared for the strenuous distance and elevation, and carry extra water for them, especially given the limited shade.

Generally, no specific hiking permits are required for day use on trails within the San Mateo Canyon Wilderness. However, a California Adventure Pass may be required for parking at some trailheads within the Cleveland National Forest. It's always best to check the latest regulations with the Cleveland National Forest service before your visit.

Accessing the Tenaja Falls trailhead, a common starting point for this loop, can involve navigating a winding, one-lane dirt road. Specific parking details can vary, so it's advisable to research the most current parking information for the Tenaja Falls Trailhead or other access points like the Morgan Trailhead before you go.

A substantial portion of this trail lacks shade, particularly after the initial creek sections. It is crucial to carry ample water, especially during warmer periods. Other essentials include sturdy hiking boots, sun protection (hat, sunscreen), layers of clothing, snacks, a map or GPS device, and a first-aid kit. Be aware of poison oak along the trails.

The San Mateo Canyon Wilderness boasts high biodiversity. You might see various bird species, mammals, reptiles, and amphibians.

Yes, this comprehensive loop combines several paths. The route includes significant sections of the Tenaja Falls Trail, the Morgan Trail, and the San Mateo Peak Trail, offering a diverse experience through the wilderness.

Beyond the overall difficulty, hikers should be prepared for several specific challenges. These include potential creek crossings that require sure-footedness, slippery rocks near Tenaja Falls (especially when wet), and possible overgrowth after wet winters. Poison oak is also present along the trails, so it's wise to know how to identify and avoid it.

The trail does pass along a flowing creek, such as Morell Creek, and near Lion Spring. However, these are natural sources and their flow can vary seasonally. It is always recommended to carry ample water for the entire duration of your hike, as natural water sources should not be relied upon without proper filtration.
