Half Moon Cay, Holland America Line’s private Bahamian island, celebrated its 15th anniversary this Caribbean cruise season, and to commemorate the milestone the cruise line has enhanced island offerings and features.

Guests to the island will notice five new, colorful, two-story Beach Villas available for rent during each call. The luxury hideaways boast exclusive hot tubs on the second floor and provide private accommodations for guests while they relax and experience the island’s highlights.

Other beach cabanas were refreshed, and the Grand Cabana received new décor and a slide from the cabana deck straight into the ocean.

“For 15 years, Half Moon Cay has continuously been recognized as the most popular private island in the Caribbean, and to celebrate this milestone we have added several new features,” said Richard Meadows, executive vice president, marketing, sales and guest programs. “Our guests already rate Half Moon Cay as their favorite Caribbean port call, and these new enhancements will make the island even more enjoyable.”

A new glass-bottom boat that carries 290 guests also was introduced for tours and features underwater viewing of the island’s colorful reefs and sea life. The horseback riding tour is one of the island’s most popular, and six horses were recently added to the herd so more can enjoy the ride.

The enrichment of the island’s features extended to the Bahamian Church, which has been repainted and outfitted with new pews and interior artwork.

The island’s private chapel is nestled in a garden overlooking the sea and provides the perfect setting for cruise guests to enjoy a unique, romantic wedding ceremony or vow renewal.

Over the past 15 years, Half Moon Cay — with its beautiful, crescent-shaped white-sand beach and warm, blue-green waters — has evolved into an idyllic playground for cruise guests while retaining the scenic natural beauty of the 1,700-acre uninhabited Little San Salvador Island. Recently it was named best private island for the 12th consecutive year by Porthole Cruise Magazine.

On the island guests can find solitude just a short walk down the beach or rollicking fun at Captain Morgan’s Bar. Half Moon Cay offers shore excursions ranging from a swim with stingrays to a horseback ride and swim.

The 700-acre lagoon offers water sports on its protected waters. New amenities and shore excursions have been gradually added to Half Moon Cay over the years, always with an eye to protecting the island’s natural beauty and preserving its status as an important migratory-bird sanctuary.
