Jupiter Mountain (elevation 4,498) towers more than one thousand feet above Bouquet Reservoir. It’s possible to visit both Jupiter and neighboring Juno Peak, known also as Jupiter Mountain West, with a few hours of rigorous hiking. The views from both summits are among the best in north Los Angeles County.

From the turnout, follow the dirt fire road uphill through a grove of pines. In about one hundred yards, the road splits with the left fork heading steeply up an eroded fire break and the right ascending at a more mellow grade. Though the climb to Jupiter via the left fork (more than 1,000 feet in less than a mile) will be trying, there are advantages to taking this route. If you only have time for Jupiter, this route will get you there more quickly and after all of the steep climbs and descents, hiking the loop in this direction (clockwise) will allow you to end the hike with a moderately graded, easy going descent.

The road climbs sharply to a bend where you get views of the reservoir. It then continues its relentless ascent up the exposed fire break, briefly leveling out half a mile from the start and about 550 feet higher. At this bump, Jupiter’s summit comes into view. Two more steep ascents bring you to the summit, one mile from the start, where you can sit on a bench and enjoy some well-earned rest and enjoy a 360-degree view including the reservoir, the high desert, the distant Tehachapi Mountains and more.

With most of the climbing out of the way, you can now add Juno Peak, clearly visible to the west, without too much difficulty. A single-track trail descends steeply from the summit over occasionally loose and rocky terrain. You drop to a saddle (1.3 miles) where an unsigned but clear trail branches off to the right; this is the return route. Continuing along the ridge, the trail makes one last steep descent to a saddle before beginning the climb to Juno Peak. At 2 miles from the start, you reach Juno’s summit (elevation 4,431). The views are similar to those from Jupiter Peak, including a particularly dramatic perspective on San Francisquito Canyon.

When ready retrace your steps back to the saddle (2.7 miles) and bear left on the single-track. It makes a pleasant traverse along the oak chaparral-covered north slope of Jupiter Mountain, with nice views of Spunky Canyon Road below. At 3.6 miles, the trail ends at a dirt road. Follow the dirt road a short distance to the start of the loop and retrace your steps back to the parking area.
