Admittedly this mountain doesn't offer much summitting interest in comparison to the surrounding peaks in the Palisades region, but after having climbed it, I would say that a trip to the summit is well worth the effort if you're in the area. You have some really nice views of Polemonium Peak and Mt Sill from an angle that few people have seen these peaks from. It also has a stellar view of the Palisade Crest, with Gandalf Peak rising prominently above the jagged ridgeline - in fact Mt Jepson can easily be 'bagged' while climbing the Crest, as they both share the same approach from the east or the west.
While the peak is easy by technical rating, it is still quite a physical challenge to reach the summit. All routes to the peak require significant cross-country travel over rough terrain. The easiest approach is via the South Fork of Big Pine, where one must climb up through Scimitar Pass, gaining some 6,500 ft round trip.
First ascent information used from R.J. Secor's "The High Sierra" guidebook.
If you're staying the night, you must park at the backpacker's parking lot, about 0.5 miles back down the road.

Camping is also available in most areas of the John Muir and Sequoia/Kings Wilderness areas. For north side approaches, by far the most popular camp location is found along the shores of Elinore Lake. With shade and easy access to water, Elinore Lake is only about 1 1/2 miles from the summit.
On the south side, suitable campsites can be found along the John Muir Trail in the vicinity of Palisade Lakes or lower down in Deer Creek Meadow where Glacier Creek joins Palisade Creek. Higher campsites in more barren surroundings can be found in Palisade Basin or along the shores of Lake 3559m.
