Surfing Honolua Bay, staying at an aromatherapy institute in Makawao, renting a car and driving to Hana, swimming at Red Sand Beach in the rain (and having it all to ourselves), hiking to Waianapanapa Falls, staying in a treehouse in Hana, driving the backside of the island from Hana to Kihei, discovering hidden swimming holes, and eating at Choice Health almost every day.
Have a night out at Mama's Fish House and order the locally caught Opah. Rent a snorkel and explore Honolua Bay. Skip the hotels (and crowds) and stay in an AirBnb - stay with a local and they might even tell you about some secret spots. Stroll through the charming town of Paia and grab breakfast at Paia Bay Coffee.
