There are about seventeen or eighteen wineries on Vancouver Island - many many more vineyards. There are "Wine Tour" road signs along the backroads from the Saanich Peninsula (near the ferry terminal) to the Cowichan Valley (at Duncan) across the inlet.
From Swartz Bay at Lands End Road at the peninsula's northern tip, the coastline-hugging road passes million-dollar waterfront homes and full views of Saltspring Island. Each winery has its own tasting room and retail outlet, open from spring to fall and by appointment in off seasons. A ferry across the inlet from Brentwood Bay to Mill Bay bypasses the Malahat.
