Milestone anniversaries call for a measure of just-us indulgence. Celebrate with your significant other by sharing built-for-two activities at these island getaways.

5 years: Salt Spring Island, B.C.

One of British Columbia’s southern Gulf Islands, hospitable Salt Spring Island welcomes couples seeking adventure in the great outdoors. Enjoy each other’s company while cycling the island’s quiet country roads, kayaking on its wildlife-rich waters or hiking one of its many rainforest trails (visit the top of Bruce Peak for a breathtaking view of Georgia Strait). Put aside at least an afternoon to explore the village of Ganges for its art galleries, bookstores and a Saturday market featuring island-made arts, crafts and food products.

10 years: Saint Martin

This is a vacation spot in which to celebrate compromise and compatibility. On Saint Martin, residents know all about sharing. It’s one of the smallest islands in the world to be shared by two nations (France and the Netherlands). With its distinctive Dutch, French and Caribbean culture and gorgeous stretches of sand, this pretty island has much to offer. Dine at French restaurants in Grand Case, browse duty-free shops on Philipsburg’s Front Street and visit any of 37 beaches, including the popular Happy Bay and Simpson Bay Beach.

25 years: Grand Cayman

Known for its five-star resorts, glitzy shopping and unforgettable scuba diving, a trip to Grand Cayman is the ultimate silver anniversary splurge. Once you’ve checked in at a top resort, activities include strolling the soft, white sands of Seven Mile Beach, visiting quirky attractions like Cayman Crystal Caves and diving in warm waters teeming with marine life. Memorable anniversary meals can be had at Blue by chef Eric Ripert, LUCA Restaurant on Seven Mile Beach and farm-to-table dining spot, The Brasserie.

50 years: Bermuda

When you’ve been together 50 years, you deserve a fuss. In Bermuda, a golden anniversary will be given the recognition it deserves. This pretty isle offers diverse distractions that include manicured gardens, historic forts, pink-sand beaches and charming museums that speak to Bermuda’s British heritage. As the honourees of the hour, be sure to take a traditional horse and carriage ride around the island to receive congratulations from locals, walk hand in hand with your spouse through one of the island’s many moon gates, believed to bring good luck to couples, and have family and friends ready with champagne to cheer your celebration.
