Saint Martin is one of the smallest islands in the world divided between two nations (France and The Netherlands). But exactly how big is it, and how long would it take to explore the entire island? Below, we provide all the details you need to know.

How Many Kilometers Does Saint Martin Cover?
The island of Saint Martin has a total surface area of 87 km² (34 square miles). Of this, the French part, Saint-Martin, covers 53 km² (20 square miles), while the Dutch side, Sint Maarten, spans 34 km² (13 square miles). This unique division has existed since the signing of the Treaty of Concordia in 1648.
The island may seem small, but it boasts an impressive diversity of landscapes, from white sandy beaches to lush green hills like Pic Paradis, the highest point at 424 meters above sea level.
Natural Changes Over Time
Some natural events have influenced the changes on the island:
- Coastal Erosion and Sedimentation: Surrounded by the Caribbean Sea, the island has experienced coastal erosion, slightly altering the shape of its beaches and shorelines. On the flip side, sedimentation in certain areas has contributed to the creation of new sandbars and small islets near places like Simpson Bay Lagoon.
- Hurricanes and Climatic Impact: Hurricanes are a recurring phenomenon in the Caribbean and have played a significant role in shaping Saint Martin’s landscape.
- Hurricane Irma in 2017, one of the most devastating in recent history, not only caused extensive damage to infrastructure but also reshaped some coastal areas, eroding beaches and altering vegetation. Although the island’s official size did not change, these natural disasters left a marked impact on its geography.
- Seismic and Tectonic Activity: Saint Martin lies in a region of moderate seismic activity. Over millennia, tectonic plate movements have influenced the island’s formation. However, in modern times, there haven’t been significant changes in the island’s size or elevation due to seismic activity.
How Long Does It Take to Explore by Walking, Car, Public Transport, and Boat?

- Walking: If you’re an avid hiker, you might consider traversing the island on foot. However, it’s uncommon due to the heat and lack of connected trails. It could take 16 to 20 hours to walk from end to end, depending on your route and fitness level. Be prepared for elevation changes and tropical conditions.
- By Car: Traveling by car is undoubtedly the most practical and quickest way. The island has a road network connecting major attractions, and you can drive around the whole island in just 1 to 2 hours, depending on traffic and how many stops you make to enjoy the views.
- Public Transport: Public transportation in Saint Martin mainly consists of minibuses that operate irregularly, especially on the French side. Getting around this way could take 2 to 3 hours, factoring in waiting times and the limited schedule.
- By Boat: Exploring Saint Martin with a boat charter is an unparalleled experience. The coastal perimeter can be covered in a few hours. Many visitors opt for our boat charters in St Martin to explore the island moving on a boat.
