Why Simpson Bay Lagoon Matters

Simpson Bay Lagoon is the cruising heart of Saint Martin and one of the most important sailing hubs in the Eastern Caribbean.

Protected from ocean swell and supported by world-class marinas, boatyards, provisioning services, and marine trades, the lagoon serves as a major base for cruisers, charter fleets, and yacht owners exploring the Leeward Islands.

Its strategic location provides easy access to Anguilla, St. Barthélemy, the British Virgin Islands, Antigua, and the wider Eastern Caribbean cruising circuit. Whether arriving from the Virgin Islands, preparing for an offshore passage, or spending an entire season in the northeastern Caribbean, Simpson Bay Lagoon is often a key stop along the journey.

Today, the lagoon remains one of the region's most important centers for sailing, yacht maintenance, provisioning, and Caribbean cruising culture.

Simpson Bay Lagoon Harbor Guide

Simpson Bay Lagoon is one of the most important cruising destinations in the Eastern Caribbean, serving as a major center for marinas, yacht services, provisioning, and seasonal cruising activity. Located on the Dutch side of Saint Martin, the lagoon provides extensive protected waters, multiple marina options, and access to one of the region's largest concentrations of marine businesses.

Cruisers arriving in Simpson Bay Lagoon will find excellent support facilities including fuel docks, marine supply stores, repair services, boatyards, provisioning opportunities, and transportation connections through Princess Juliana International Airport. The lagoon's extensive marine infrastructure makes it a popular location for vessel maintenance, seasonal storage, charter operations, and passage preparation.

The lagoon is connected to the Caribbean Sea through the Simpson Bay Bridge and serves as a natural gateway to nearby cruising destinations including Anguilla, St. Barthélemy, Saba, the British Virgin Islands, Antigua, and the wider Leeward Islands chain.

For many sailors, Simpson Bay Lagoon functions as both a destination and a strategic base of operations. Some cruisers remain for only a few days while provisioning and preparing for their next passage, while others spend an entire season enjoying the island's sailing culture, restaurants, beaches, and extensive marine services.

Visitors should expect a busy and active marine environment, particularly during the winter cruising season when transient yachts, charter vessels, and long-term cruisers arrive from throughout the Caribbean and North Atlantic.
