The RV dump station, also known as a sani-station, is located at the entrance to the park. It is across from the service area and information shelter. When using the RV dump station, make sure to bring loonies and toonies as the payment machine does not accept bills. The station provides potable water for drinking and rinse water (non-potable) for other purposes. To get to the RV dump station, you need to take Highway 6 and head east from Vernon to Lumby. Once in Lumby, follow the signs and turn north onto Mabel Lake Road. This road follows the Shuswap River for 36 km (22 miles) and offers a beautiful view of farmland and ranches. After that, you will need to travel 1 km (6/10 mile) on a gravel road to reach Mabel Lake and the campground where the RV dump station is located.
