This is an exciting kickoff to backpacking season
—an opportunity to connect, have fun, and challenge yourself by attempting the four “Grand Slam” peaks just outside Boise:

  • Kepros (5,428 ft)
  • Lucky Peak (5,904 ft)
  • Mt. Heinen (6,336 ft)
  • Cervidae Peak (4,987 ft)

Important: You are NOT expected to complete all four peaks. Choose the hikes that work best for you—this is not a competition.
