Scan the thermals above the western Pyrenees (they're much less frequently encountered in the central and eastern parts of the range) and you will almost certainly spot the prehistoric-looking griffon vultures (Gyps fulvus) which soar above the mountains in search of carrion to feast on.
Around 100 nesting pairs of griffon vultures have made their home on the limestone cliffs of this 82-hectare reserve and CCTV cameras allow you to see inside their nests from the visitor center.
The on-site museum also does a good job of explaining the life history and conservation status of vultures (including the much rarer Egyptian vulture and the massive lammergeier) in the Pyrenees.
