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. It is walkable on both sides from here to Twin Falls, and is beautiful no matter which portion you choose to visit.

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.

If you are starting your ride here on the Palouse to Cascades trail, take a few minutes to stop and admire the view then ride out past the watershed education center to the "Thou shalt not pass" signs (and really - do NOT trespass. The watershed folks are serious.) This is the official start of the Trail!

All told, the remade rail line known as the Palouse to Cascades Trail — also known as the Iron Horse or John Wayne trails — contains more than 100 miles (161 km) of trail from Cedar Falls to the Columbia River, all in a state park that only measures 100 feet (30 m) in width. This trail's very gentle grades make for pleasant hiking, and surprisingly beautiful views when the trees open up at magnificent trestle bridges. The trail is very popular with cyclists as well.

Rainbow Lake is a glacial lake in Olallie State Park. There is a gravel path circumnavigating it. Riders can get nice views of Rainbow Lake from the Snoqualmie Valley Trail, which runs between the trees.
