This Cingles de Tavertet des de Sau viewpoint shows a beautiful panoramic view of the Sau reservoir and the surrounding mountains. At the bottom of its waters lies the town of Sant Romà de Sau since 1960, when the water completely covered the small town, condemning houses, gardens and memories to live underwater. If it coincides that you are pedaling this Route in a dry period, you will be able to see the tip of the bell tower of the town's church.

View towards the Monastery

Highlight • Viewpoint

Here you have a good view of the monastery and the swamp. The pity is that there are some industrial buildings in the background.

Sau Dam Tip for Bikepackers When riding near the Pantà de Sau (Sau Reservoir), don’t miss stopping at the Sau Dam viewpoint. It’s a spectacular spot to catch your breath and take in the sweeping views of the turquoise reservoir framed by steep cliffs and lush forests. 🌊 If water levels are low, you might even spot the famous submerged bell tower of the old village of Sant Romà de Sau poking out of the water — a haunting and iconic sight that adds a unique story to your ride. 🛑 Keep in mind the area around the dam can be a bit steep and technical on gravel roads, so take it easy if you’re loaded up. 💡 Pro tip: Early morning or late afternoon light here is magical for photos and gives you cooler temperatures for climbing or descending.

In this year 2024, the Sau reservoir has suffered one of the greatest droughts since there are records, in 1963 was the year it was inaugurated to leave Sant Romà de Sau under its waters, This Sau swamp in the Ter River... It would serve to supply water 💧 for many regions, since in those times we already had periods of lack of water to supply the basic needs of the population.

A great place even if the reason why this village reappears after 60 years is more than sad. Water shortage in Catalonia.

It is worth leaving the main trail and going down to see the old bell tower and the church of Sau on the other bank without trees in the middle

When the water is not very high, there is a great beach here and you can see the bell tower of an old church that was being flooded when the dams were built.
