Trailhead: Hyak Trailhead

This is not your typical hike as we'll be spending the majority of it (4.6mi out of 5.3mi) in an old railroad tunnel. It makes for a unique experience.

Now, why would this hike be planned for the middle of the day, especially the hottest part of it? It's simple, the tunnel has natural A/C (it's cold so a jacket is recommended) and the darkness of the tunnel contrasts nicely against the brightness of the afternoon sun.
