Chaski Bay is a feature of Crater Lake within Crater Lake National Park in Oregon, USA. It is a coastal bay on the lake's southeastern shore, situated between Eagle Point and Dutton Cliff. The bay is directly below the towering Vidae Cliff, which rises approximately 2,000 feet above the water. A notable natural feature is Chaski Falls, a small waterfall that flows directly into the bay. The lake's water is famously deep blue and exceptionally clear, with descriptions noting its Caribbean-like blue-green hue and the ability to see all the way to the bottom in the bay. The primary and only practical means of accessing Chaski Bay for paddlers is via the Crater Lake boat tours, which regularly schedule trips that pass through the bay. These tours depart from Cleetwood Cove, which serves as the sole legal launch point for private and tour boats on the lake. Paddling in Chaski Bay is subject to the strict regulations of Crater Lake National Park, which manages all water access. The bay offers dramatic views of geological formations, including the nearby Phantom Ship rock formation and the sheer cliffs of the caldera rim. Wildlife sightings, such as great blue herons, have been recorded along its shore.
