Saint Barthélemy Travel Tips

Must-see hotspots

Gustavia harbour, St-Jean Beach, Shell Beach, Colombier Bay, Gouverneur Beach, luxury boutiques, and hillside villas with ocean views.

Data planning

Light travelers can manage with 2-4 GB/week for maps, messaging, and photos. If you stream video, share lots of media, or work remotely, consider 8-15 GB. You can top up easily with Simology while on the island.

Insider tips

  • Many hotels and restaurants offer Wi‑Fi, but use your eSIM for secure, reliable access—especially when booking excursions or taxis.
  • High season runs December through April with luxury events and yacht visits. Summer is quieter and great for lower prices and relaxed island life.
