The Tamolitch Blue Pool is a captivating natural landmark nestled within the Willamette National Forest in Lane County, Oregon. Known for its strikingly vibrant blue water, this deep pool is the re-emergence point of the McKenzie River, which flows underground for several miles through ancient lava beds. Situated at an elevation of approximately 758 meters, the pool lies at the base of what was once Tamolitch Falls, now a seasonal waterfall.
Visitors are consistently drawn to the mesmerizing turquoise hue of the Tamolitch Blue Pool, a color created by the unique geological process of the river seeping through porous lava. The pool's enduring allure is also attributed to its remarkably cold water, hovering around 3°C, which contributes to its pristine clarity. The dramatic setting, surrounded by old-growth Douglas fir forests and ancient lava flows, adds to the sense of wonder.
Reaching the Tamolitch Blue Pool typically involves a hike along a section of the McKenzie River Trail. The most common approach is a 5.8-kilometer out-and-back route from the trailhead, which features an elevation gain of about 87 meters. Hikers should be prepared for varied terrain, including sections through a dry riverbed and old lava flows, and be mindful of steep cliffs along the path. Parking can fill up quickly, especially during peak seasons, so an early start is often recommended.
The best time to visit the Tamolitch Blue Pool is generally during the spring and summer months, though these periods also see the heaviest foot traffic. The McKenzie River Trail welcomes hikers, bikers, and runners, making it a versatile destination for outdoor enthusiasts. While the Tamolitch Falls themselves are seasonal, the blue pool remains a year-round spectacle, offering a unique experience regardless of the water flow above.
The geological history of the Tamolitch Blue Pool is particularly fascinating. Around 1,600 years ago, a lava flow from Belknap Crater buried a three-mile stretch of the McKenzie River. The river now flows beneath this ancient lava, only to resurface at the pool, creating its distinctive appearance. The pool's depth, surprisingly around 9 meters despite its clear appearance, adds to its mystique, as does its name, Tamolitch, inspired by the Chinook jargon word for "bucket."
Whether you're seeking a challenging hike or a scenic stroll, the area around the Tamolitch Blue Pool offers numerous opportunities to explore. You can discover various Tamolitch Blue Pool trails and routes, from family-friendly options to more strenuous paths.

While it has an elevation gain of 87 meters and varied terrain including lava flows, many families with children enjoy it. However, there are sections with steep cliffs, so close supervision of children is essential. Consider the fitness level of your family and ensure everyone has appropriate footwear.
Are dogs allowed on the trails to Tamolitch Blue Pool?
Yes, dogs are welcome on the trails leading to Tamolitch Blue Pool. It is important to keep them on a leash at all times, as required by the Willamette National Forest regulations and for their safety, especially near steep drop-offs and during busy periods.
What is the best time of day to visit Tamolitch Blue Pool to avoid crowds?
To experience Tamolitch Blue Pool with fewer people, it's highly recommended to arrive early in the morning, especially on weekends and during the peak spring and summer seasons. Parking fills up quickly, and the trail can become heavily trafficked by mid-morning.
Can you swim in Tamolitch Blue Pool?
While the vibrant blue water of Tamolitch Blue Pool is incredibly inviting, swimming is not recommended. The water temperature is extremely cold, consistently around 3°C (38°F), which can be dangerous due to the risk of hypothermia. The pool is also surprisingly deep, about 9 meters (30 feet).
Are there any alternative routes or loop options for hiking to Tamolitch Blue Pool?
The most common route is the 5.8-kilometer out-and-back trail from the main trailhead. While there isn't a direct loop around the pool itself, the Tamolitch Blue Pool is part of the larger McKenzie River Trail. Experienced hikers and trail runners can extend their adventure by continuing along the McKenzie River Trail for longer distances, creating more challenging out-and-back or shuttle options.
What is the geological reason for the pool's distinctive blue color?
The striking turquoise hue of Tamolitch Blue Pool is due to a unique geological phenomenon. The McKenzie River flows underground for several miles through ancient lava beds, which were formed by a lava flow from Belknap Crater about 1,600 years ago. As the water seeps through the porous lava, it filters out sediments and picks up minerals, causing it to re-emerge with its characteristic clear, vibrant blue color.
Is there public transportation available to reach Tamolitch Blue Pool?
Public transportation options directly to the Tamolitch Blue Pool trailhead are generally not available. Visitors typically need to drive to the trailhead. It's advisable to check local shuttle services or ride-sharing options if you do not have personal transportation, though these are not commonly offered for this specific location.
What should I pack for a hike to Tamolitch Blue Pool?
For a comfortable and safe hike, pack plenty of water, snacks, and wear sturdy hiking shoes. Layers of clothing are recommended as temperatures can change. Don't forget sun protection (hat, sunscreen), a first-aid kit, and a camera to capture the stunning views. If hiking in cooler months, bring extra warm layers.
Are there any facilities like restrooms or picnic areas at the trailhead or along the trail?
There are usually basic restroom facilities available at the main trailhead for Tamolitch Blue Pool. However, there are typically no additional facilities like restrooms or designated picnic areas directly along the 5.8-kilometer trail to the pool. Visitors should plan accordingly and pack out all trash.
How does the Tamolitch Falls, above the pool, become seasonal?
The Tamolitch Falls, which once flowed constantly, became seasonal due to water diversion for hydroelectric use in the 1960s. This diversion, along with the natural underground flow of the McKenzie River through lava beds, means the falls only flow during periods of heavy runoff or when water is intentionally released from upstream dams. Otherwise, the river emerges directly into the Blue Pool below.
Are there any nearby cafes or restaurants after the hike?
The Tamolitch Blue Pool is located in a relatively remote area within the Willamette National Forest. While there are no cafes or restaurants directly at the trailhead, you can find dining options in nearby towns such as McKenzie Bridge or Sisters, which are a drive away from the trail.
