The sauna also has twin mobile saunas at the Nelson Yacht Club, which the website says has two wood-fired hot rooms and sea views. We hear that sessions run Friday to Sunday at Cable Bay, so check the days before you go. Prices are listed as sale prices of $130 and $240 as at 2026. Private bookings open three weeks ahead and communal bookings two weeks ahead. Guests need swimwear and two towels, and the website says the sauna is for guests aged 16 and over. Free public parking is available, and public toilets are nearby. Our pick in Cable Bay for a hot sauna session with a plunge in the sea.
