Index, Washington, is located at the confluence of the North Fork and South Fork of the Skykomish River. The town is also one mile north of State Highway 2 at milepost 35. Its location by the river and the highway provides clear bearings, while climbing at the Town Wall is its most distinctive activity. Trails on Heybrook Ridge and along the North Fork, along with historic sites, offer other ways to explore. This makes it possible to plan your trip around the focus you prefer.
Climbing at the Town Wall
The Stimson Bullitt Climbing Preserve is next to Index and offers climbing on the rock formations of the Town Wall. The Index Town Wall has more than 600 climbing routes, only a few of which are below grade 5.10. The number of routes may change over time. The climbing season lasts nearly year-round; conditions are wetter in December and January. The seasonal information and difficulty ratings offer different guidance for planning a day of climbing.
The Lower Town Wall near Index is also part of the town’s climbing history. On March 13, 2026, Washington State Parks announced that it had agreed to manage the Lower Town Wall as a climbing park and permanently maintain public access for climbing there. A trail east of the Town Wall climbing area leads to the Upper Town Wall. From there, you can see Mount Index and the town of Index.
Trails to viewpoints and the riverbank
Access to Heybrook Ridge is via the Heybrook County Park Trailhead, across the Skykomish River from the town center. The trail climbs 700 feet over 1.5 miles to a viewpoint. Nearby Heybrook Ridge County Park has a trailhead with an accessible parking space and a portable restroom.
The Crescent Trail offers a different destination: it leads through the forest from the town of Index to an informal town park on the banks of the North Fork of the Skykomish River. While the Heybrook Ridge trail climbs to a viewpoint, the Crescent Trail leads to a park by the river.
Outdoor activities on the Skykomish River
Outdoor Adventures rents whitewater and inflatable kayaks, e-bikes, and rafts at the River House in Index. Reservations are subject to availability. The River House is also the meeting point for a rafting trip on the North Fork of the Skykomish River; availability varies by season. If you plan to take this trip, confirm availability in advance. These offerings distinguish between equipment rentals and a rafting meeting point.
Local history and a summer festival
Pioneer Park is home to the saw used to cut granite at the Index Quarry in the early 20th century. Index is also on the original route to the gold and silver mines of nearby Monte Cristo. Redmen’s Wigwam and Bush House are listed on the National Register of Historic Places and add to the town’s historical landmarks.
The Index Historical Society offers historical walking tours of Index year-round upon request for groups of five to twelve people. Availability should be confirmed in advance. In summer, the Index Arts Festival takes place at Pioneer Park; check the event dates before your trip. A historical tour and a festival visit can therefore be considered as different reasons to travel to Index.
