Telescope Peak is also notable for having one of the greatest vertical rises above local terrain of any mountain in the contiguous United States. Its summit rises above the lowest point in Death Valley, Badwater Basin at, in about, and about above the floor of Panamint Valley in about. This is comparable to the rises of other tall, but better known, U.S. peaks. It is even somewhat comparable to the rise of Mount Everest above its northern base on the Tibetan Plateau, a rise of roughly. However Everest rises much more, and much more steeply, above its southern base in Nepal. Since it is the high point of a range surrounded by low basins, Telescope Peak also has a particularly high topographic prominence of, ranking it 22nd in the contiguous US by that measure. A variety of trees can be found on the mountain, including single-leaf pinyon, limber pine, and, at the highest elevations, the ancient Great Basin bristlecone pine.
Climbing
From Ridgecrest, California State Route 178 leads northeast into Death Valley National Park. The road turns to unpaved about later as it loses its highway status. It winds up through Wildrose Canyon up to a parking lot where the trail for the summit starts. The section from the Charcoal Kilns can be rough and might only be suitable for 4-wheel-drive cars with high clearance, depending on weather conditions. Hiking Telescope Peak by the normal route involves a round trip hike. The trail starts in the western part of Death Valley National Park at Mahogany Flat campground. The trail slowly winds itself up to the summit later at a steady gradient of roughly 8%. The standard route is maintained by the National Park Service, and no permit is required to climb the mountain. This route leaves directly from the Mahogany Flat Campground, and travels approximately two miles to Arcane Meadows. From Arcane Meadows, the trail winds five more miles gradually up toward Telescope Peak, mostly following the ridgeline to the summit. This route can also be used to access two nearby peaks, Bennett Peak and Rogers Peak, a traverse that adds on minimal extra mileage. An established, but more advanced, climbing route is from Shorty's Well to the summit of Telescope Peak at. This route is approximately 30 to 34 miles round trip and provides a net gain of elevation of approximately. The route begins at the intersection of the WestSide Road and the Hanaupah Canyon Road. For 6.5 miles, the route climbs out of the Badwater basin and into Hanaupah Canyon. Approximately 1.5 miles after reaching the end of the road, the trail leads directly to Hanaupah Spring, a seasonal water source that may not be available year-round. At the spring, the route then turns directly north onto a scree/talus slope. Although this slope may look difficult to ascend, this is the correct way. Climbers should find the best route possible up the slope. Once finished climbing the talus slope and reaching the ridgeline, climbers should then should follow the ridgeline West to the Telescope Peak summit, which should be readily apparent. The Shorty's Well to Telescope Peak route can be completed in one day by experienced hikers, and has one of the largest elevation gains that can be obtained up a single summit; it can be descended either via Mahogany Flat or as a round-trip back to Shorty's Well. , California looking south with Telescope Peak at left at left and Panamint Valley at right
