The best (paved) road into the north end of Mabel Lake heads east from Enderby, following the Shuswap River upstream. Be sure to stop to at various points (Cooke Creek, Skookumchuk, etc.) to look at the river along the way. As you approach the lake, the road really ends at the RV Park/Golf Course/Airstrip/Resort and there is some limited access to the lake there, but there is a good access at the marina which sits at the mouth of the river.
Mabel Lake is a large lake – 35 km long. There is no road along the west shore and only a Forest Service Road along the east side north of Mabel Lake Provincial Park starting at the south end.
We enjoyed paddling out into north end of the lake. For a short paddle, aim north towards Tsuius Narrows and cross the lake to the mouth of Tsuius Creek, then follow the shore south to Cottonwoods Beach. There is a 20 site BC Forest Service Campsite there with a sandy beach.
For a longer paddle, the north end of the lake is about 14 km. Noisy Creek campsite is on the west shore.
