Easy: waterfalls and lakes
The Snoqualmie Falls trail itself is 1.4 miles round trip with a 250-foot climb back up. Twin Falls in Olallie State Park is the best easy waterfall hike nearby, about 2.5 miles round trip with 500 feet of gain to a 135-foot falls. For a flat walk, stroll the shore of Rattlesnake Lake or a stretch of the Snoqualmie Valley Trail, a former rail line.
Moderate: Little Si and Rattlesnake Ledge
Rattlesnake Ledge climbs about 1,160 feet in 2 miles to a cliff-top view over Rattlesnake Lake; it is crowded but worth it. Little Si is a similar effort, about 3.7 miles round trip and 1,300 feet of gain, with a rocky summit facing Mount Si. Both suit fit beginners and older kids.
Hard: Mount Si
The Mount Si trail gains about 3,150 feet in 4 miles to a viewpoint at roughly 3,900 feet. Locals use it to train for bigger mountains, and for most visitors it is a full day out. Start early, carry water and layers, and expect snow near the top from late fall into spring.
