Best Hiking Trails in Mount Si Natural Resources Conservation Area

Overview

Mount Si Natural Resources Conservation Area is a nature reserve in Washington.

Mount Si towers over the city of North Bend, 35 miles east of Seattle. The Haystack at the top of the tree-covered mountain is one of the four mountain summits in the Mount Si Natural Resources Conservation Area (NRCA). The others being Mount Teneriffe, Green Mountain, and Little Si. Established in 1987 to protect the area's natural resources, including old growth forest, wildflowers, and wildlife habitats (mountain goats, in particular). Several streams drain into the neighboring Middle Fork NRCA or North Fork Snoqualmie River.

Getting Started

Mount Si NRCA is north of I-90 and is available for day-use only.

Mount Si Trail is arguably the most popular trail in the area, at just 40 minutes away from Seattle. Little Si trail is an easy-to-navigate hike with less mileage and elevation gain than Mount Si, making it a good trail for families. Combine the trails within the area for a challenging training day, such as Teneriffe Falls Loop via Teneriffe Trail and Mount Si Trail. Depending on the hike and weather, chances are you'll be rewarded with views of Mount Rainier and other surrounding mountain peaks once above the trees.

When to Go

Even though the higher mountain summits will retain snow in the winter, hikers visit the trails year-round, though the best weather conditions are June through September. Be prepared for crowded trails, especially on the weekends.
