Delta is about 22 kilometres south of downtown Vancouver. By car, take Highway 99 south from Vancouver and exit at Ladner/Tsawwassen (Highway 17). BC Transit runs the 601 and 620 bus routes from Vancouver connecting to Ladner and Tsawwassen, but service is limited and a car is much more practical for visiting Westham Island or Burns Bog.
The Tsawwassen BC Ferries terminal, at the southern end of Highway 17, runs frequent services to Swartz Bay (Victoria) and Nanaimo on Vancouver Island, and to the Southern Gulf Islands. This is the main reason most travellers pass through Delta.
