Best Cave Tours -- Wet and Wild (2002)

Spring Cave
White River National Forest

At 7,000 feet, Spring Cave, which opens May 1, is one of the longest caves in Colorado, located less than a mile from the South Fork Trailhead, east of Meeker. In springtime, the stream that flows through the cave widens to form "Emerald Lake," which makes a full wetsuit a requirement for anyone heading into the back sections.
