Cape Verde (especially Boa Vista, Sal, and Maio) is the 3rd largest nesting area for Loggerhead (Caretta caretta) sea turtles worldwide, active from July to October.

Never use white light flashlights or camera flashes on the beach at night. Artificial light disorients the nesting turtles and prevents them from laying eggs.

If you encounter a turtle on the beach, stay back (minimum 15 meters), stay quiet, and always position yourself behind her field of vision.

Only book nocturnal turtle-watching tours with certified local guides or recognized ecological NGOs (like "Projecto Biodiversidade" or "Biosfera").

The majestic dunes of Boa Vista and Sal act as natural shields, protecting the islands from accelerated coastal erosion.

Avoid driving 4x4 vehicles or quad bikes over the top of delicate sand dunes. Always stick to established dirt tracks.

Do not collect shells, pieces of coral, or volcanic rocks from beaches as souvenirs. Leave nature exactly as you found it.

When scuba diving or snorkeling, never step on or support yourself on live coral formations; a small impact can take decades to recover.

The Atlantic Ocean around Cape Verde can harbor very strong invisible rip currents, even on apparently peaceful days.

Always respect beach safety flags: Green (safe to swim), Yellow (extreme caution required), Red (danger - do not enter).

At wild beaches without active lifeguards (such as Santa Mónica on Boa Vista or Ponta Preta on Sal), avoid venturing far from the shoreline.

Before diving into any new or remote beach, always ask local residents about underwater currents, rocky shelfs, and shoreline breaks.
