On the west coast of La Palma, under the cliffs of Tazacorte, there's a sea cave that changes colour depending on how the light falls inside: Cueva Bonita, the "pretty cave". It won't show up on any road map, because there's no way to reach it by land. The only way in is by boat, and that alone makes it worth a sea trip of its own.
It's a volcanic cave carved into the base of the cliffs on the island's west coast, hollowed out by the sea in dark basalt rock. Light bounces off the water and tints the inside in shades of blue and turquoise that shift with the hour and the state of the sea. There's no path, no staircase, no way in on foot: the only way to look inside is to pull up alongside it in a small boat.

The way to see it is the dolphin and whale watching cruise with a marine biologist, which sails from the port of Tazacorte aboard the Flipper. It lasts 3 hours and costs €60 per adult. A marine biologist travels on board explaining the pilot whales and dolphins that live off this coast, with a 96% sighting success rate according to the operator, and the boat is wheelchair accessible. The meeting point is the local partner's office at the port's marina; transport there isn't included.
The same cruise takes in two other spots you can only see from the water:
Drinks and photos on board are included in the price; lunch isn't.
Can you walk to Cueva Bonita? No. It's a sea cave at the base of the Tazacorte cliffs, with no access by land. It can only be seen from a boat.
How much does it cost to see Cueva Bonita? The cruise from Puerto de Tazacorte that passes the cave costs €60 per adult and lasts 3 hours, including a marine biologist guide, drinks and photos.
What else does the same cruise cover? Besides Cueva Bonita, the route passes Porís de Candelaria and the volcanic delta left by the 2021 eruption on the Tazacorte coast, while looking out for dolphins and whales along the way.
