Emerald Cave is a glowing rock alcove on the Colorado River in Black Canyon below Hoover Dam, typically reached by kayak or guided paddle from Willow Beach. Midday sun lights the green water; wind and motorboat wakes can pick up by afternoon. Lake Mead NRA rules apply—no cliff jumping—and river levels vary with dam releases.
