Baie Rouge — Red Cliffs Beach with Hidden Cave
Pink-red sand, turquoise water, and a secret cave at low tide.
Why Go
Baie Rouge (Red Bay) on the French side near Sandy Ground is a picturesque beach defined by its distinctive pinkish-red sand and surrounding red cliffs. The turquoise water, excellent snorkeling, and a hidden sea cave accessible at low tide make it one of the most photogenic and adventurous beaches on St. Martin.
The Experience
Baie Rouge gets its name from the reddish tint of the sand and the dramatic red-orange cliffs that frame the beach. The color contrast against the turquoise water creates a visual that is strikingly different from the typical white sand Caribbean beach. Swimming is lovely in the calm, clear water, and snorkeling along the rocky edges and cliffs reveals an underwater world of colorful fish and coral. The highlight for many visitors is the hidden cave at the south end of the beach — accessible only at low tide, you can swim or wade into a sea cave carved into the red cliffs. The beach is less crowded than Orient Beach or Maho, attracting a more adventurous and local crowd who appreciate the natural beauty and the cave exploration opportunity.
What to Try
Explore the hidden sea cave at low tide — swim or wade in and discover the cave's interior. Snorkel along the cliffs for colorful fish and marine life. Photograph the red sand and cliff contrast against the turquoise water. Walk the full length of the beach for different perspectives. Sunbathe on the unique colored sand.
Insider Tip
The sea cave is only accessible at low tide — check tide times before visiting and plan to be at the south end of the beach when the tide is lowest. The beach has minimal shade, so bring an umbrella or arrive early for natural cliff shadow. Baie Rouge is partially clothing-optional at its far ends, following the French beach tradition. Parking is limited — arrive early on weekends.
