Today, Deep Cove serves as the starting point for Doubtful Sound cruises on tour boats stationed at a small wharf in Wanganella Cove, within Deep Cove. The full-day tours depart from Manapouri by boat to travel across Lake Manapouri, followed by a bus ride over Wilmot Pass, and return the same way after the boat tour in Doubtful Sound. The wharf in Deep Cove is also used for unloading large components such as transformers from barges, to be delivered to the Manapouri Power Station via Wilmot Pass, as there is no other road access to the power plant and these components would be too large to ferry across Lake Manapouri from the other side.
