Where can I book a glass-bottom boat trip to explore the marine life around Mallorca?

The turquoise waters along Mallorca's southeastern coast offer brilliant views beneath the surface, especially around coves such as Cala Mondragó and Cala Llombards. Several operators run glass-bottom boat excursions, giving a unique chance to see the colorful fish and Posidonia seagrass meadows that protect the island's marine ecosystem. You can usually book trips from ports in Palma, Cala d’Or, and Portocolom. Many local companies have websites with online booking available, or you can arrange a tour through your hotel or a local travel agency, particularly if staying near the coast.

During the warmer months, these tours are popular and fill up quickly, so reserving in advance—including through agencies in towns like Alcúdia or Pollensa—is wise. Some boat trips combine snorkeling stops or take you close to isolated beaches like Es Trenc, where the blend of crystalline waters and coastal scenery makes for a memorable day. If you prefer a more relaxed pace, the small harbors of Port de Sóller or Port de Pollença also offer glass-bottom boat outings that showcase the rich underwater life along the Tramuntana coast. Whether you’re launching from Palma’s marina or a quieter fishing village, booking ahead ensures you catch this special glimpse beneath the waves.
