Snorkeling in Cascais: Sailing & Swimming

Sail out, drop anchor, and snorkel in a bay instead of following a fixed route

A 90-minute snorkeling activity in Cascais where you sail along the coast or anchor in calm bays to swim and snorkel, with all equipment provided. The trip is built around what you want to do: swim, snorkel, or simply soak up the sun with drinks and your own music on board. A guide in English, Spanish or Portuguese is with you throughout.

The experience

Ninety minutes on the water means you're not locked into a long commitment. The boat heads out along the Cascais coast or anchors in a quiet bay depending on conditions and what you want that day. Once anchored, you get snorkeling gear and the freedom to enter the water at your own pace. There's no choreographed group moment, no schedule forcing you in or out.

What makes this different from a standard tour boat is the setup itself. You choose the music, bring your own playlist, and the guide adjusts the day around what appeals to you. A swim, a snorkel, a few drinks in the sun, or a mix of all three. The itinerary is yours to shape. The boat stays small and the group stays personal, so you're not competing for space or waiting for stragglers.

Snorkeling equipment is included and ready on board. The guide speaks English, Spanish or Portuguese and knows the local waters well enough to find the spots worth visiting and read the conditions that make them safe. Service animals are welcome, and if you're traveling with an infant, specialized seats are available.
