Hiking

The Sahalie Falls, Koosah, and Tamolitch Falls via McKenzie River Trail offers a captivating journey through ancient forests and past stunning waterfalls. You'll traverse a path characterized by old-growth trees, lava rocks, and sections that can be rugged, leading you to the mesmerizing, ice-cold turquoise waters of the McKenzie River. The highlight is undoubtedly the vivid blue Tamolitch Pool, where the river dramatically re-emerges after flowing underground, creating a truly unique natural spectacle. This moderate 10.4-mile (16.8 km) hike, with 939 feet (286 metres) of elevation gain, typically takes around 4 hours and 36 minutes to complete.

Planning your visit to this popular section of the McKenzie River Trail means aiming for an early start, especially on busy days, as trailhead parking can quickly reach capacity. While no specific permits are usually required for this route, it's always wise to check for any updates before heading out. The trail is best enjoyed during drier seasons to avoid overly muddy conditions, ensuring a more comfortable experience as you navigate the hilly and sometimes rocky terrain.

This trail is a prime example of the geological wonders found in the Willamette National Forest, showcasing how ancient lava flows have shaped the landscape. The unique phenomenon of the McKenzie River disappearing underground and reappearing at Tamolitch Pool makes this a truly special destination. It's a fantastic way to experience the natural beauty and distinctive features of the region, offering a memorable adventure for those seeking a rewarding day hike.

Highlight • Lake
