Want to explore Benagil caves in the Algarve? You’ll now have to pay to enter.

Benagil caves near Lagoa in the Algarve, a truly magical area your correspondents have previously explored on an inflatable dingy and by, you know, simply swimming, have been getting too many visitors, so the authorities have been working on new ways to protect their fragile environment.

Here are just two of the rules they came up with, according to The Portugal News:

•⁠ ⁠”Prohibition of renting kayaks without a guide in the Benagil caves area;

•⁠ ⁠Prohibition of access to the caves by swimming or with buoyancy aids”

Happy exploring with a guide.
