Campgrounds and RV parks near One Hundred Mile House, BC

100 Mile House sits on Highway 97 in British Columbia's South Cariboo, roughly 90 kilometres south of Williams Lake on the Cariboo Plateau. The district municipality is the primary service centre for the South Cariboo and serves as a base for RV travellers exploring the surrounding Interlakes region, with hundreds of small fishing lakes, ranchland, and mixed aspen and lodgepole pine forest within easy driving distance. RV parks in town and along the highway corridor cater to travellers passing through on the Cariboo route as well as anglers staying for a week or more. 100 Mile Motel and RV Park sits on the highway close to town services, while Big Country Campground and RV Park offers another in-town option. Lakeside choices within a short drive include Cariboo Bonanza Resort, Martens Resort, and Martens Resort and RV Park, which serve RV travellers heading to lakes east of town along Highway 24, the corridor locally known as the Fishing Highway. The surrounding area is best known as a fishing and paddling destination, with dozens of stocked rainbow trout lakes and quiet backcountry water accessible within an hour's drive.

Private RV parks in and around 100 Mile House take reservations directly by phone, email, or through their own websites. Peak-summer sites at lakeside resorts, including options like Cariboo Bonanza Resort and Martens Resort, book up weeks or months ahead for July and August weekends, so early booking is strongly recommended. Provincial park campgrounds in the region use the BC Parks reservation system. As of 2026, BC Parks uses a three month rolling window for campground reservations, reduced from four months in 2025, which means arrival dates can only be booked within the three month window. At Green Lake Provincial Park, reservations are accepted for Emerald Bay and Sunset View campgrounds, and first-come, first-served sites are also available at those campgrounds, as well as at Little Arrowhead. Recreation Sites and Trails BC operates smaller forest-service campgrounds in the surrounding backcountry; most remain first-come, first-served, so arriving mid-week improves the odds of finding a spot.
