What to expect on Snoqualmie Tunnel – Snoqualmie Tunnel loop from Hyak
This route is a journey through history and nature, primarily following a flat, wide gravel path that is part of the larger Palouse to Cascades State Park Trail. The undeniable highlight is the 2.3-mile long Snoqualmie Tunnel, a pitch-black, chilly passage that offers a truly exciting and atmospheric experience. After emerging from the tunnel, you'll be treated to scenic views of the Snoqualmie Valley and surrounding Cascade Mountains, including peaks like Granite Mountain and Denny Mountain. While the path is generally easy, the consistent coolness and darkness inside the tunnel require a bit of preparation, but the reward is a memorable ride.
Planning your visit
The Snoqualmie Tunnel is typically open from May to October, so plan your trip within these months. Parking at the Hyak trailhead requires a Washington Discover Pass, or you can purchase a day pass on site. Restrooms are available at the trailhead. Crucially, you'll need a strong headlamp and additional lights for navigating the 2.3-mile dark tunnel, and layers are essential to stay warm in the tunnel's consistent 50°F (10°C) temperature.
