I visited this WHS in May 2014. There was no information apart from a few hiking trail signs and no sign anywhere informing people that this is a WHS or indeed a national park for that matter. Over the internet I found a list of different trails that do pass from the main core zone of this WHS and since I didn't want to spend days of hiking after having visited the Ordesa Valley a couple of days before, I opted for the shorter hike from Encamp to Engolasters which offers a couple of panoramic views and a few streams of water from the melting snow on the mountain peaks. In Engolasters, at 1616 metres, there is a lake in a glacial depression with clear turqoise water and plenty of fish. There's also a small church originally built in the 11th-12th century called Sant Miquel d'Engolasters which is very similar to the ones in the Val de Boi in Catalonia, Spain. Those were the main highlights of my visit together with the many birds of prey present in the valley. More effort should be made by Andorra to provide some information boards along the various hiking trails and to promote this WHS instead of only promoting the many shopping centres only.
