El Capitan Cave Interpretive Site

El Capitan Cave is the longest mapped cave in Alaska. Cavers mapped over two miles of passage from the main entrance. The only way to see this magnificent cave is during the summer months, when visitors can take advantage of a no cost guided tour given by Forest Service employees. A locked gate guards the cave's entrance to protect against vandalism and possible damage from otherwise well-meaning individuals, as well as to keep inexperienced cavers safe from its hazards. The tour meets at the parking lot and leads visitors on a somewhat strenuous, steep trail that climbs 1,100 feet to a viewing deck that is at an elevation of 250 feet, right at the mouth of the cave. The tour then proceeds inside the cave for approximately 500 feet and includes information about cave (karst) geology and archeological discoveries. The tour lasts approximately 2 hours. To reserve a cave tour, call the Thorne Bay Ranger District at (907) 828-3304 Monday - Friday, 8:00 a.m. to 4:30 p.m., at least 2 days in advance. Tour groups are limited in size to six people. Babies in packs or carriers are not allowed, nor are children under seven years of age. Precautions: The trail to the cave is strenuous and steep. There are no trails or lighting in the cave. Hazards include low ceilings, pits, and slippery, uneven ground. Footing is very uneven and only those with very sure footing and good agility should attempt the tour. What to bring: At least one flashlight per person (optional) and sturdy footwear. Helmets and headlamps are required and are provided by the Forest Service at the site. Wear warm clothing as the cave temperature is a constant 40 degrees Fahrenheit. Wet and muddy conditions are the norm.
