Enjoy the views of Meadowbrook Slough, actually an oxbow lake surrounded by wetlands.

Alice Creek Campground is right at the trailhead for the CDT. It’s free, first-come-first-served, with basic sites, a vault toilet, and access to some great hiking or riding. Bring bear spray and be prepare for the gravel road.

The Palouse to Cascades State Park Trail is a long gravel route across Washington, great for bikepacking or long rides. The Snoqualmie Tunnel is a must—dark, damp, and fun (bring lights). Expect wind and remote stretches, so pack water and gear. Riding over trestles and through changing landscapes keeps things interesting the whole way.

The Hall Creek Trestle is a historic steel and timber railway bridge built in 1912. It was once the old Milwaukee Road until, in 1988, a storm washed away a central 171-foot section of the bridge. In the 1990s, Washington State Parks restored the trestle, reconnecting the east and west segments of the former rail line, which is now part of the Palouse to Cascades (Iron Horse) Trail. The views down into Hall Creek Valley are genuinely stunning and worth the ride!

The South Fork Snoqualmie River begins near Snoqualmie Pass and flows for over 30 miles before merging with the main Snoqualmie River in North Bend.

Great views from here. And... the middle of the trestle is different than either end because it had collapsed and was rebuilt in the late 90's

It's much longer than that. This is my favorite long distance bike trail in Washington, almost 290 miles. You can start at Rattlesnake Lake near North Bend and ride all the way to Idaho - or vice versa. Most of the trail is still on the old railroad bed (with a few detours), so it's beautiful and remote. Make sure you check the Washington State Parks website for maps, directions, advice and to register to go on the trail. It's free but mandatory if you are going east of the Columbia River. And... it's a bucket list item.
