Signal Mountain Summit Road, Grand Teton National Park

(4.6/5 based on 340+ reviews on the web)
Signal Mountain is an isolated summit standing above sea level. The mountain is located in Grand Teton National Park in the U.S. state of Wyoming. The next closest higher summit is more than distant, and this isolation provides sweeping views of the Teton Range, much of the northern Jackson Hole area as well as the Snake River. Though located adjacent to the Tetons, Signal Mountain was not formed in the same manner or period. The mountain originally was formed by volcanic ashfall from one of the eruptions of the Yellowstone hotspot. The peak is also partially a glacial moraine formed by a receding glacier that came south out of the Yellowstone icecap. This same glacier also created neighboring Jackson Lake.Signal Mountain has a 5mi long road providing vehicular access to an observation area located just below the main summit. The Signal Mountain Trail is a hiking trail that goes from Signal Mountain Lodge to the summit and covers a distance of. The trail splits mid-way for a portion of approximately 1.5mi, allowing hikers to take either a trail along the lower part of the ridge or south of the ridge past a series of small ponds. The trails then rejoin and steepen over the last mile to reach the secondary summit of the mountain, the Jackson Lake Overlook. The trail rises approximately 800ft from the lodge to the overlook, though on the ridge trail there is quite a bit of up and down that adds a few hundred feet to the cumulative elevation gain. The trail is a hiking only trail, mountain biking and horseback riding are not permitted by the park service. The road is a popular biking destination due to the difficult climb up and then (after turning around at the summit) continuous downhill experienced on a 3.5mi portion of the road.

  • The view from the signal mountain is wonderful, but by the many incredibly aggressive mosquitoes we broke off our expedition pretty soon.

  • A pleasant ride with a great view of the valley below. We were hoping to see wildlife and we did see several deer. The view of the valley - or "hole" as I guess it was called - was great from the top of the mountain. If you have the time, take this trip.
  • We saw a young bull elk trying to fight/play with tepees wood..another tourist was outside his car and the elk challenged him...horns galore. Good pictures of elk. The view was great...we went about 9am...
  • It's a good view over Jackson Hole, but I wouldn't say it's that spectacular (the view). Consider stopping by Jackson Dam on your way, that one has amazing view of the Tetons over Jackson Lake.
  • Fun and pretty drive up the mountain with a great view at the top.
  • The drive up the narrow road to the summit is worth the exciting views you get from there.
