The experience
I didn’t expect to feel slightly nervous stepping onto a completely clear boat. It’s like walking on water but with this weird thrill in your stomach. The harbor at Sesimbra was already busy, people shouting greetings and the smell of fish from the morning catch still hanging around. Our guide, João, grinned when he saw me hesitate and tapped the glassy floor with his sandal: “It’s stronger than it looks, promise.” He was right. After a minute I stopped thinking about it and just watched the blue-green waves sliding beneath my toes.
The coastline looked different from down here. You could see every ripple, every bit of seaweed waving below. When we got closer to Praia do Ouro, João slowed us down so we could look for fish: little silver flashes darting under us. Someone pointed out a jellyfish (I flinched), but João just laughed and said they’re harmless this time of year. The air tasted salty and sharp. I kept brushing hair out of my face because the wind was everywhere. At one point, I caught myself just staring at the shifting light on the rocks, not even thinking about photos for once.
We stopped near Praia do Ribeiro do Cavalo for swimming. The water was cold enough to make you gasp but so clear you could see your own feet kicking below. There were only five of us on board: felt kind of intimate, like we’d lucked into something private. Bottled water appeared out of nowhere (João again), and he joked about how locals never get tired of this view. I’m not sure I would either. On the way back, everyone was quiet for a while: maybe just letting it all sink in or maybe tired from swimming, hard to say.
