Horne Lake Caves Provincial Park
Park Provincial park featuring limestone caves and trails
Limestone cave system on Vancouver Island with guided tours, spelunking routes, walking trails and campgrounds for family outings.
Horne Lake Caves Provincial Park protects a system of limestone caves and karst features on Vancouver Island in British Columbia. The park is known for recreational caving and commercial guided tours that explore developed caves.
Visitors can choose from easy guided show-cave routes to more challenging, rope-assisted caving experiences; the park also offers hiking and nearby camping facilities. Trails and interpretive material highlight cave formation and karst processes rather than built attractions.
The caves were formed by dissolution of limestone and subsequent karst development, with passages and caverns shaped by groundwater over geological time. Recreational use began in the early 20th century and organized tours became established later.
The park lies on central Vancouver Island near the small community of Horne Lake and is accessed from the east via Highway 4, west of Qualicum Beach and Parksville.
- Tours: Guided cave tours run seasonally and cover walk-in show caves as well as more technical routes for experienced cavers.
- Access: Accessible from Highway 4, the site is a common day-trip destination from communities on eastern Vancouver Island.
