Real Journeys organised this marvellous overnight cruise. Doubtful Sound has many different arms and the cruise explored many of them. Saw NZ fur seals, woke up to see a school of dolphins accompanying the boat. The trip included activities such as kayaking, swimming and visiting the shoreline on a tender boat. Food excellent and staff very attentive. This trip is a must if you want to see untouched nature at its best - feel privileged to have seen such virgin wilderness. Thank you, RJ!
