Crystal clear water, amazing caves & spectacular scenery make Horne Lake one of the best camping & adventure destinations on Vancouver Island. Horne Lake Caves was rated #1 Attraction by TripAdvisor. Explore this unique park above and below the surface. Visit Canada's only Cave Theatre and Museum. On the trails, enjoy a wide range of programs from Fossil Geology Hikes to family-oriented cavern tours or the popular 3hr. Spelunking Adventure featuring ancient fossils & amazing crystal formations. For more challenge, you can self-guide two rugged caves or push it to the limits on the "Extreme" expeditions - rappelling down a seven-storey underground waterfall! Build your skills on the 2 hr. Vertical Rappel sessions descending natural rock outdoors. Spectacular lakefront camping right next door.
