What to Expect

Round Pass Trail is one of those quiet Longmire-area routes that most visitors blow right past on their way to the showier destinations. Starting from the forested lowlands near Longmire, the trail winds through old-growth Douglas fir and western red cedar, with the kind of cathedral-like canopy that makes Rainier's west side feel like another world entirely. The path climbs steadily through moss-draped forest before opening up at Round Pass, where you get a satisfying window into the surrounding ridgelines without the crowds that plague Paradise or Sunrise. This is not a glamour trail — there are no dramatic waterfalls or glacier viewpoints — but the deep forest atmosphere and genuine solitude make it a perfect pick for hikers who want to experience Rainier's quieter, wilder personality. Best suited for those who find peace in the woods rather than the alpine.

Safety Advisory

The Longmire area sits in prime black bear habitat — make noise on the trail and store food properly. Bear encounters here are more common than on the busier east-side trails.

Trail conditions can deteriorate quickly in shoulder season with fallen trees and washed-out sections. Check with the Longmire Wilderness Information Center for current status before heading out.

Pro Tips

Trail Tip

Start from the Longmire area early morning when the forest light filters through the old-growth canopy at its most atmospheric — the west side of Rainier holds morning mist longer than anywhere else in the park.

Trail Tip

This trail sees minimal maintenance compared to the flagship routes, so bring trekking poles and expect some blowdown and muddy stretches, especially in early season before trail crews make their rounds.

Trail Tip

Pair this with a stop at the Longmire Museum and the nearby Trail of the Shadows loop to make a full half-day out of the quieter side of the park that most visitors never bother to explore.
