Walking backward while talking is useful for leading a tour, demonstrating a moonwalk, or retreating from a room full of ominously staring toddlers. See the reverse saunter put to good use with today's Groupon: for $12, you get two tickets to a guided cave tour at Indian Caverns in Spruce Creek (up to a $26 value).
A subterranean treasure-trove, Indian Caverns' labyrinthine passages and vast chambers provide adventurers exciting jaunts through natural rock formations and Native American artifacts. The 60- to 90-minute tour covers about one mile of underground pathways, showcasing the ever-changing limestone features and bat top hats that line the cavern's insides. Expect to see a wide range of natural rock formations, including flowstone, stalagmites, and stalactites, getting along and pumping fists to classic-rock anthems. Along the way, the knowledgeable tour guides furnish factoids and insights on the cave's geological features and history—from being a storage unit for aboriginal arrowhead hoarders to operating as a highway robber's hidey-hole.
Indian Caverns' surrounding area provides plenty to see and do before or after the cave tour. In addition to the visitors' center, the surrounding valley offers idyllic scenery and wildlife-spotting opportunities, and the banks of the meandering Spruce Creek contain choice picnic spots for picky bears and opportunities for catch-and-release fishing (additional fees apply for fishing, and a permit is required).
Extending up to 140 feet below ground level beneath a foothill of the Allegheny Front, the natural limestone formations of Indian Caverns yield beautiful glimpses of the Earth's inner geological mechanics. The majority of the cave's stalagmites, stalactites, and flowstone are actively growing at a pace of 1 cubic inch every 120 years, just like the hair of a petrified cave mouse. Knowledgeable guides lead tours along nearly 1 mile of the cave's length in an hour, pointing out limestone formations and such cave wildlife as brown bats and salamanders from the comfort of an artificially lighted walkway. Guides recommend that visitors wear comfortable walking shoes and a light sweater, jacket, or the warmer half of a two-person horse costume as the cavern stays a constant 56 degrees Fahrenheit throughout the year.
As tour-goers gaze on the cave's beautiful features, a guide elucidates its rich history from the first limestone deposit formed 405 million years ago to its opening to the public four months before the stock-market crash of 1929. Many Native-American artifacts were found in the cave during development and can be seen both inside the cavern and at the gift shop.
