Signal Mountain Road

No driving tour through Grand Teton National Park is complete without a drive to the summit of Signal Mountain for sweeping vistas of the Teton Range and surrounding valley.


  • Signal Mountain Road is 5 miles long and RV’s and trailers are prohibited.
  • This road is closed during the winter months.
  • Get the best view of the Teton Range at the observation area at Signal Mountain summit.
  • Marvel at hillsides covered with wildflowers during the early summer months.


The scenic Signal Mountain Road is a five mile, 1,000 foot climb of switchbacks to an observation area at the top of Signal Mountain. Set far apart from the next highest mountain peak, Signal Mountain provides breathtaking views of the Tetons’ towering peaks, the flat glacial plains below, Jackson Lake and the Snake River beyond.
