Old Mailbox Peak Trail (1-way)

3.2 mi • 4,314 ft gain • Class 1

Highlights

  • Celebrated by masochistic Seattle-area hikers for the no-nonsense Old Mailbox Peak Trail: 4000 ft vertical gain over 2.5 miles
  • The New Mailbox Peak trail is much tamer with many switchbacks... but far longer at 4.7 miles up.
  • Yes, there's a mailbox on the summit. Do you have any mail waiting for you up there? When's the last time you checked?
  • A popular training hike in the early season to prepare for bigger Washington peaks in late summer.
  • Mailbox Peak is a sub peak of trail-less Dirtybox Peak.
