The experience

So you're standing at Lagos Marina and the boat's already there: an 18-seater RIB with padded benches, which sounds like a small detail until you're actually sitting on it for two hours and your back isn't screaming. The engine fires up and you're moving past Alvor, then Portimão, then Carvoeiro, and the whole time the Algarve coastline is just... there. Golden cliffs, small beaches tucked into the rock, the water shifting from turquoise to deep blue. Your guide knows the route and points things out without being annoying about it.

First stop is the Carvoeiro caves: smaller, but the water inside is so clear you can see straight down, and the rock formations are doing something that makes you understand why people travel for this. Then you're moving again, heading toward the thing everyone came for: Benagil. The cave opens up like a cathedral, and the light comes through the opening in the roof in a way that feels almost deliberate. You can't get out of the boat or swim, that's the trade-off, but honestly, from the water looking up, you get the whole picture. The guide gives you time to just sit with it. No rushing.

Bring a windbreaker because the spray is real and the wind picks up once you're away from the marina. A water bottle helps too, though nothing with an open top. The boat trip to Benagil caves from Lagos takes you past working fishing villages and empty coves, and by the time you're heading back, you've seen a chunk of the Algarve that most people miss because they're stuck on a beach or in a town. Life jackets are on you from the start: non-negotiable, and honestly, it's one less thing to think about.
