Mount Si is one of best and most popular hikes near Seattle. The mountain, originally referred to by Native Americans as 'Kelbts,' borrows its current name from a mid-1800s farmer, Josiah 'Uncle Si' Merrit. Due to the close proximity to the city, the trail is often busy with hikers, climbers, and miscellaneous adventurers. Incredibly, this trail sees approximately 80,000-100,000 users per year.
