Lagos & Benagil Cave: Dolphin Watching Tour with Biologist

Summary

Wild dolphins near lagos and benagil cave by boat with marine biologist

You’ll leave Lagos behind on a fast boat with local guides and a marine biologist, searching for wild dolphins before gliding into Benagil Cave’s glowing light. Expect close-up dolphin sightings, fun facts from your guide, and time to soak up Algarve’s dramatic coastline — it’s more than just photos; it’s that feeling you get when nature surprises you.

What’s the experience like?

We set off from the Marina de Lagos before I’d even finished my coffee — the sea air kind of woke me up better anyway. Our skipper, João, had that easy way of talking that makes you feel like you’re just out with friends. The boat felt sturdy but quick, and there was this salty tang in the air that stuck to my lips. I didn’t expect to laugh so much right at the start; our marine biologist, Rita, handed out these little fact cards about dolphins and teased us about who’d spot them first.

The first pod showed up maybe half an hour in. It’s hard to describe — they just appear, all at once, like someone flipped a switch underwater. There was this hush as everyone leaned over the side (maybe too far), and then one kid squealed when a dolphin arched right next to us. Rita pointed out how to tell which species we were seeing (I forgot immediately, sorry Rita), but honestly I was just caught up watching their backs slice through the water. The engines were quiet enough that we could hear them breathing — sort of a soft puff each time they surfaced.

Afterwards we hugged the coast towards Benagil Cave. Sun bounced off the cliffs and there was this weird mix of sunscreen and seaweed smell — not bad, just very “Algarve”. João slowed down so we could take photos of those famous fruit-shaped rocks inside the cave (no landing though). I tried to say “Gruta de Benagil” properly; Rita laughed and said my accent made it sound Italian. Fair enough.

On the way back I sat by myself for a bit near the bow. The wind was colder than I thought it’d be for June. I kept thinking about how close those dolphins came — like they didn’t care about us at all, or maybe they did in their own way? Anyway, if you want something real from Lagos — not just another beach day — this dolphin watching trip is probably it.
