Eggshell Cave is a captivating yet relatively obscure cave located on Vancouver Island, part of the extensive cave systems that characterize the region. While not as famous as some of the island's more prominent caves, such as those in Horne Lake Caves Provincial Park, Eggshell Cave holds its own allure. Known for its delicate formations and serene underground environment, it offers a unique experience for those willing to venture off the beaten path. The cave's name, "Eggshell," likely derives from the fragile, thin layers of calcite and other minerals that adorn its walls, resembling the delicate nature of an eggshell.
