The giant “M” towering above Moreno Valley on the southeast slopes of Box Springs Mountain is a familiar sight to those traveling on the 60 freeway and a popular destination for Inland Empire hikers, especially those in the Riverside area. Many opt for the short but steep east route from Hidden Springs, but the M can also be reached via a longer hike, starting at the Two Trees Trail. Unfortunately, Box Springs Mountain Regional Park suffers from trash and graffiti and if there is smog, the views along the way to the M might disappoint, but this is still a challenging and worthwhile hike, especially if you have already hiked to the M from Hidden Springs. If you are short on time, you can drive to the top of the Two Trees Trail and start from there.

Most of the work happens on the Two Trees Trail, which gains about 950 feet in 1.3 miles. The trail starts out innocently enough, crossing a seasonal stream shaded by sycamores and willows, but that amounts to false advertising as the steady climb begins almost immediately. Expect to stop and catch your breath as you climb through the canyon. If visibility is good, the views west toward Riverside and the San Gabriels beyond are a reward for your efforts. The trail passes by numerous interesting geological formations as well.

The trail ends at Box Springs Road which comes up from Moreno Valley, the driving route for people who want to start at the upper trail head. Turn right and head past a picnic area with a restroom and begin the next leg of the hike. Although most of the distance is still ahead of you, you have already done well over half of the total elevation gain. Head south on the wide dirt road. In a short distance, you have the option of taking the single-track Spring Trail, which shaves off about 0.2 mile but involves more climbing. After the Spring Trail rejoins the dirt road, your climb continues around a hairpin turn before leveling out. You pass by multiple antenna installations before reaching the upper end of the M Trail coming up from below.

Just after the junction, bypass the antenna facility on a use trail to the right of the fence. This leads you to an overlook just above the “M” (which will appear more like a Greek “Epsilon” from this angle). If the air quality is good, your view includes San Jacinto, the Santa Anas, the San Gabriels, San Bernardinos and more. You also get an impressive view of Moreno Valley and the 60 freeway some 1500 feet below.

After enjoying the views, retrace your steps back to the Two Trees Trail. If you have set up a car shuttle, you can continue another 2 miles down the M trail to the Hidden Springs parking area.

  1. Hi, Can you tell me more about the difficulty level. I am committed to taking a group of 6-8 year old boys on this rail tomorrow and I think it may be too hard for them. Do you think with lots of rest breaks it kis doable for that age? Is it dangerously steep? Thanks!
