Since the indefinite closure of the Garcia Trail, this short but challenging hike has become a favorite of San Gabriel Valley and Inland Empire residents in search of a quick, rigorous workout. The essence of this hike is two short but very steep and loose trails: the Poopout and Punk Out. Those who slug out the difficult ascent will be rewarded with panoramic views of the San Gabriel Valley and beyond.
The Poopout Trail wastes no time ascending from the east side (opposite the parking area) of Glendora Mountain Road, gaining more than 500 feet in less than half a mile. Recent rains have caused erosion, adding to the challenge of an already loose and slippery trail. Near the top, you get a short breather before making one final push to meet the Monroe Truck Trail. By this point you have gained 750 feet of elevation in only 0.6 mile.
The next 0.4 mile, on the Monroe Truck Trail, is the eye of the storm, a pleasant jaunt along a ridge that quietly gains another 100 feet. On the right (south) is Big Dalton Canyon; to the left you can see the Lower Monroe Truck Trail’s twisting course. However, straight ahead, the intimidating contour of the Punk Out Trail plunges straight up the ridge, an ominous reminder of the task at hand.
One mile from the start, you reach a wooden marker indicating the start of the Punk Out Trail. The lower part of this trail isn’t too bad – there’s even a brief descent – but much of the work comes in the last 0.3 mile, which gains 400 feet. As with the Poopout Trail, erosion has made the terrain more difficult; unless you have the agility of the acrobat from the film “Ocean’s 11” expect to use your hiking poles. The brutal climb reaches a false summit where the grade becomes a little less severe before rejoining the Monroe Trail.

The views from this spot are predictably impressive, including the San Jose and Puente Hills, downtown L.A. and on clear days, the ocean. If you are up for more climbing, you can continue another 0.2 mile and 100 feet to Summit 2760 or even farther along the Monroe Truck Trail. Otherwise enjoy the view and rest your legs for the steep descent.
