Hamilton Island Activities. Hamilton Island Resort has the widest selection of activities in the Whitsundays: game fishing, snorkeling, scuba diving, waterskiing, parasailing, jet skiing, wakeboarding, sea kayaking, speedboat adventure rides, and fish-feeding tours are all on the agenda. Everything can be booked through the island's central tour desk. The use of nonmotorized watercraft is free to resort guests through the Beach Hut (Hamilton Island Beach Sports) on Catseye Beach, with Beach Hut staff ready to give assistance, tips, and—for a fee—lessons. If the Coral Sea doesn't tempt you, there are well-marked walking trails, quad-bike and ATV tours, twilight 4WD "bush safaris," go-karts, a nine-pin bowling center, a target-shooting range, an aquatic driving range, public-access swimming pools, and an 18-hole golf course on nearby Dent Island. The island's sports and fitness complex incorporates a state-of-the-art gym, a whirlpool spa and sauna, squash and floodlit tennis courts, and a mini-golf course. You can also sign up for various tours, cruises, and special events.
