Things to know before booking a Big Cat Green Island cruise

  • Booking window: Popular full-day and family options can sell out 3-5 days ahead during peak season (June-October and holidays).
  • Half-day vs. full-day: Half-day gives 2 hours on Green Island; full-day gives 5 hours, more time for the rainforest trails, beach, and any add-on activities.
  • Choosing your add-on: Snorkel gear, glass-bottom boat, and semi-submarine are all built around the same base cruise, pick based on whether you want to be in the water, dry but viewing, or fully submerged-viewing without swimming.
  • Reef type: Green Island is inner reef, calmer, shallower water, easier for beginners, though lower coral density than an outer reef trip. Wondering how it compares? See our inner vs. outer reef guide.
  • Island facilities: Cafés, restrooms, walking trails, and shaded areas are available on Green Island; full-day cruises give the most time to use them.
  • Boat and transfer: Large, stable catamarans with indoor lounges and outdoor decks; about 45 minutes each way.
  • Best time of day: Morning departures are quieter with better snorkeling visibility.
  • Weather: Cruises run in most conditions; calm days improve underwater visibility.

Big Cat's long operating history (since 1990) comes up often in reviews, alongside the semi-submarine as a standout for travelers who want reef views without snorkeling. Reviewers frequently mention the buffet lunch as a genuine highlight rather than an afterthought.
