Olympic Hot Springs - Boulder Creek - 4.8 Miles Round-Trip

The Olympic Hot Springs are located 2.4 miles from Appleton Pass Trailhead in the Elwha River Valley of Olympic National Park. A network of 7 or more pools comprise the hot springs, which geologists believe form as surface water percolates down to the earth's interior, is heated and rises back through cracks in the rocks as steam and hot water. A heavy sulfur smell is common at the pools.

Temperatures up to 118 degrees have been recorded in the hottest pools. Water quality at Olympic Hot Springs is not monitored and may contain harmful bacteria. Enter pools at your own risk.


  • Olympic Hot Springs Road is closed at Glines Canyon Dam. You will have to walk the road (4.7 miles) to reach the trailhead. This adds 9.4 miles and over 1000' elevation gain to the roundtrip distance. You may bike this road segment up to the trailhead, but not on the trail to the hot springs.
  • The Crystal Creek Bridge is damaged and closed to all users. Alternative routes across the deep gorge and creek are not maintained. Travel at your own risk.
  • Campfires are prohibited at Olympic Hot Springs and Boulder Creek Campground due to damage and new revegetation efforts.

The trail rises on a wide, graded path under a fir-hemlock canopy to bridges over Cougar Creek (.3 miles : 1,835') and a second stream (1.3 miles : 2,024').

It crests (1.5 miles : 2,073) and drops to a major suspension bridge over Crystal Creek (2.0 miles : 2,043'). Once across the trail comes to a fork (2.1 miles: 2,117'); keep left and follow signs for the Hot Springs.

The trail passes Boulder Creek Campground and turns left across a high wooden bridge over Boulder Creek to the first of several Olympic Hot Springs Pools (2.4 miles : 2,084'). The trail continues 3.5 miles to Boulder Lake and 5.3 miles to Appleton Pass from the Hot Springs.

"Olympic Hot Springs Road is now open to Glines Canyon overlook, about 4-1/2 miles below the Boulder Creek (Olympic Hot Springs) Trailhead. That last 4-1/2 miles is open to hikers and bikes."

"This hike would be super easy, however, 8 miles of road is closed before the actual trailhead. Road that is also uphill nearly the entire time. So you'll end up hiking uphill 10+ miles or so, as well as back down. Bring lots of water! If you run out, it's fine, there's running waters every now and then. It's a beautiful trail but it's pretty rough getting up. We made it about 8 miles up before it got too dark because we hadn't known that it would be closed. It took us almost three hours to do so before park rangers told us to turn around and go back down. A few of us got hyponatremia so make sure you're eating plenty of sodium with that water. It's quite the workout! Good luck!"

"The Olympic Hot Springs (Elwha Valley) are currently closed (as of 12.7.15) due to a health hazard until further notice."

"A 60' piece of Olympic Hot Springs Road was washed out after the Elwha River rose to 23.19' on November 17 (flood stage is 20' and major flood stage is 23'). Many roads along the Park's west side were closed after extensive damage from the Sunday storm. Hurricane Ridge received at least 21" of snow during this time."
