Le Quarci waterfall is a big waterfall near the village of Ulassai. This waterfall is really hight, at least 70 meters from the top and it arrives until the car road, so often it's quite dangerous going there. But if you are lucky you'll see one of the most impressive waterfalls of the island.
Arriving there is not so easy and you need a couple of high wellingtons because you have to pass across the river that makes the waterfall. quite simple. Unfortunately, there aren't many other ways to get there, so being prepared, even though it should be better to call a guide. As always if you need more information or need a guide don't hesitate to contact me.
