Hyak Station

Highlight • Rest Area

The best place to stop for a rest and some food after climbing up the trail and going through the tunnel. There are restrooms, fresh water, a bike repair stand, tools and air pump and picnic tables. Oh, and a friendly sign post. If you are going from Cedar Falls to Easton, you are just over halfway there, and it's a slight downhill all the way!

Hyak

Highlight • Settlement

In 1915 the tiny town of Hyak was a train station and became a community. Today it is part of the Palouse to Cascades State Park Trail in Iron Horse State Park, showing you some of the history around the former railway that you now use for biking or hiking.

Snoqualmie Tunnel

Highlight • Structure

The tunnel is a part of the former railroad system that is the Palouse to Cascades State Park Trail. It is close to the former train station of Hyak. If you want to get into Snoqualmie Pass, don’t hike the tunnel. Take a spur trail up to WA 906 that will lead you there.

Snoqualmie Tunnel

Highlight (Segment) • Structure

One instant you're riding along a mountain trail and the next you find yourself in a completely dark tunnel (expect the tiny prick of light at the end). Soak up the sounds and the cool air as you ride under a mountain - how cool is that. Just don't forget your lights and a jacket.

Snoqualmie Tunnel west entrance

Highlight • Structure

Western end of a 2.5 mile tunnel under Snoqualmie Pass. Former railroad tunnel, now open April-September (depending on snow). Great adventure destination - you can cross the pass to the ski areas on the east side. Be sure to bring plenty of lights and a jacket - it's cold, slightly humid and very, very dark!

Annette Lake

Highlight • Lake

A stunning alpine lake where you can take on the views of Abiel Peak to the southwest and Silver Peak to the east, as well as a waterfall on the east shore. Trillium and glacier lilies peek out of the receding snow in late spring. It is an excellent halfway point to an amazing hike.
