Benagil Sea Caves: Kayak Tour Inside Hidden Algarve Grottos

Summary

Kayak through Benagil’s secret caves and swim in sunlit grottos

You’ll paddle straight from Benagil Beach into Algarve’s most famous sea caves with a local guide leading the way. Swim or wade inside Algar de Benagil’s sunlit grotto, snap photos from your kayak or on soft sand, and soak up those quiet moments only found off-shore. All gear is included—just bring your curiosity (and maybe a dry change of clothes).

What’s the experience like?

I’d seen those pictures of Benagil cave before — you know, the one with the round hole and golden sand — but paddling right up to it in a kayak felt completely different. There was this salty breeze, sunscreen on my hands, and the sound of waves slapping against the hull. Our guide, João, grinned as he handed out life jackets and cracked a joke about us looking like “bright orange penguins.” I didn’t expect to laugh so much before even getting on the water.

The group was small (maybe ten of us?), which made it feel more relaxed. We got a quick rundown about paddling — nothing fancy, just enough so we wouldn’t spin in circles. The first stretch from Benagil Beach was easy, with sunlight glinting off the water and that weird mix of sunscreen and seaweed smell. João pointed out some rock formations with names I couldn’t pronounce (he tried to teach us — I failed). Then suddenly we were gliding right into these shadowy sea caves, cool air brushing my arms. It was quieter inside than I thought it’d be. Everyone sort of whispered without meaning to.

Inside Algar de Benagil itself…honestly, it’s hard to describe without sounding cheesy. Light poured through the ceiling hole like someone switched on a spotlight just for us. A couple people swam — I dipped my toes in but chickened out because it felt cold (should’ve just gone for it). João took photos for anyone who wanted them. The sand was softer than I expected; I found myself just sitting there for a minute, staring up at that circle of sky. You don’t get that kind of silence very often.

Paddling back felt different — maybe slower? Or maybe I just wanted to drag it out a bit longer. The sun had shifted and everything looked warmer somehow. We joked about our “pro” kayaking skills (spoiler: not pro). When we finally hauled up onto the beach again, my arms were tired but in that good way where you know you actually did something. I still think about that view up through the cave roof sometimes when things get noisy at home.
