Cycle Solutions' knowledgeable, experienced guides whisk away alfresco explorers of all abilities on tours of breathtaking local surrounds. The two-hour tour of the Corner Brook Caves introduces nascent spelunkers to the earth’s underbelly and teaches them about the creation of the cavernous environments they encounter. Subterranean sojourners wend along an underground mountain stream, admiring its babbling waters and avoiding the bathing trolls. A savvy chaperone explains the forces and conditions that lead to the caves’ formation, effectively dispelling the widespread belief that caves "just happened." Visitors can explore the spacious caverns adorned with the self-portraits of ancient bats, and those with a hankering for confined spaces can shuffle through smaller caverns for added adrenalin boosts. Once the tour has concluded, grotto-goers can hydrate larynges at a fair-trade, organic-coffee house.
