A waterfall surges into a subterranean river. Towering peaks dotted with evergreen trees loom on a distant shore. A fire pit billows wood smoke into the sky, and teepees huddle around a forested campsite. At Horne Lake, certified nature guides and counsellors spend each day connecting visitors with Nainamo's natural splendour. The park accepts only off-the-grid living, with campsites disconnected from electricity and running water, and completely scentless to most mail carriers. Staffers supply canoes, kayaks, paddleboats, rods, and other gear for destination fishing, and lead hikes through rainforest trails. Certified cave guides also lead a series of excursions through the natural majesty of Horne Lake Caverns, where a network of rocky passageways wind around a subterranean river and gleaming crystal compositions reach up to four stories tall under soaring gallery ceilings. They also conduct nature-based leadership programs such as team building, ropes courses, and multiple-day summer camps.
