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.

A good, quiet trail with superb views, but with some rocks in places. Studded tires are still preferable. You'll find a water source along the way with a small ford to cross.
