Cavern Lake Trail 444 kb.pdf

DESCRIPTION:
A subterranean stream emerges from a gaping cave mouth and cascades over a series of small waterfalls. A short hike from the Whale Pass Road (Forest Road 2700) to a wooden viewing platform provides a stunning view of the cave entrance and the falls. The cave extends back about 150 feet and is open for visitors to explore. However, much of the cave floor is under water and would require wading for most of this distance.

Cavern Lake and stream flowing out with heavily forested banks

The water flowing out of this cave originates from a lake on the hillside above the cave. During the spawning season, salmon have been observed running upstream through the cave system and black bears are often seen feeding near the falls. Trout and salmon fishing are also an attraction at this spot.

 

LOCATION:
The cave is accessed by Forest Road 2700 near Whale Pass. Take State Highway 929 to State Highway 925 (Control Lake junction) turn left.  Stay on State Highway 925 for 15 miles where it turns into Forest Road 2000.  Stay on Forest Road 2000 for approximately 30 miles to Forest Road 2700. Follow Forest Road 2700 for approximately 3.5 miles (watch for signs) to the Cavern Lake Cave Trail. For a more scenic route, from Forest Road 20 turn right on Forest Road 3000 and follow this around Neck Lake and saltwater toward Whale Pass. Before reaching Whale Pass, turn left on Forest Road 2700 and watch for signs to the trailhead.

SPECIAL FEATURES:
Over 600 caves have been recorded on northern Prince of Wales island and several westerly islands. These caves contain a virtually untapped resource of information about formation of the islands, past environments, changing animal populations, and human uses of the caves. Cavern Lake Cave offers a glimpse of this unique environment, providing a living museum where you can observe and learn about karst topography and caves.

Be sure to hike Beaver Falls Karst Trail to experience first-hand some of the unique features of the karst landscape. And, take a free guided tour of El Capitan Cave, the largest known cave in Alaska and one of the longest mapped caves in the Americas.
