The Experience

I didn’t expect the first cave to echo like that — you could actually hear our laughter bouncing off the stone, mixing with the slap of water against the hull. We’d left from a little harbor (I forget the name, but it smelled like sunscreen and grilled fish), and within minutes, those cliffs started rising up around us. Our captain, João, pointed out shapes in the rocks — “elephant,” “cathedral,” “pirate’s face” — some I saw, some I just nodded along. The main keyword here is Benagil cave tour, but honestly, it felt more like drifting through someone’s old storybook than ticking off a tourist list.

We ducked into over twenty caves — João steered right inside most of them, so close you could almost touch the walls (don’t; they’re rough and kind of cold). The light inside Benagil itself was unreal: gold and green at once, with this weird hush except for distant gulls. There were other boats but not too crowded; maybe we got lucky? At one point he cut the engine so we could just float. I remember salt on my lips and that seaweed smell — not unpleasant, just real. Someone asked if these caves ever collapse; João shrugged and said “sometimes,” which made us all laugh nervously.

After all those caves and secret beaches (one was empty except for a couple napping under an umbrella), we stopped for a swim. The water was colder than I thought — took my breath away for a second. My friend tried to take photos but her phone fogged up from the spray. On the way back, João spotted dolphins in the distance; we didn’t get close but everyone cheered anyway. I still think about that light inside Benagil cave — it’s stuck in my head for some reason.
