The Allagash Ice Caves are fissure caves located on the south shore of Allagash Lake in the Allagash Wilderness Waterway, 100 miles west of Ashland by dirt roads. The caves are extensive with many formations found in the deeper passages. This is one of the more visited caves in the state yet shows little underground evidence because most people visiting the caves visit only the first fifty to one hundred feet because the caves are tight, wet and cold.
