Aitutaki Day Tour from Rarotonga
Air Raro's "Aitutaki in a day" tour
Air Rarotonga operates an Aitutaki Day Tour that includes airport transfers on Rarotonga, return flights, a one-hour tour of Aitutaki island on ‘le truck’, a Vaka Lagoon Cruise on the lagoon, use of snorkelling gear and lunch – for adult/child $599/299.50.
Book on their website, though we suggest staying a few days on Aitutaki rather than taking the day trip.
