Another from the Four Seasons portfolio, Sensei Lanai is just for adults. Found in a secluded enclave reached via a semi-private flight from Honolulu, the resort offers a quite unique experience. The wellbeing retreat has developed programmes and journeys, using a blend of science, evidence-based practices and innovative technology, led by expert practitioners. Engage in yoga, meditation, hiking and lectures, surrounded by beautiful artwork, a breathtaking sculpture garden and calming water features that help evoke an atmosphere of self-discovery. Guests staying here dine at Sensei by Nobu in a glass pavilion building, or outside, beside a koi pond.
