This dive site, Ponte Brolla Orrido, offers a unique freshwater canyon diving experience in Switzerland. Divers typically begin in shallow water at a sandbank, navigating slightly north-east towards distinctive large stones. The primary segment of the dive involves proceeding upstream against the current for approximately 150 meters, revealing a dramatic underwater landscape characterized by spectacular rock formations. After exploring the upstream section, divers drift back to the initial rock formations before turning right to return to the sandbank. A critical safety warning is in place: under no circumstances should divers venture downstream from the sandbank, as this area poses extreme danger due to white water rapids and the outlet of a power station.
As a freshwater river environment, the marine life primarily consists of various species of freshwater fish, which may include local trout, minnows, or dace, darting among the rocks. Divers might also observe crustaceans like crayfish, often found in crevices or under stones. The underwater landscape is complemented by a variety of aquatic plants that cling to the riverbed and rock surfaces, contributing to the unique ecosystem.
The best time to visit this dive site for optimal conditions is typically during periods of stable weather and lower rainfall, which usually ensures better visibility and more manageable current flows. Divers and freedivers should possess good buoyancy control and experience in navigating strong currents. This site is particularly appealing for those interested in unique geological formations and the specific aquatic life found in clear mountain rivers. Always consult local conditions before diving and strictly adhere to the safety warnings concerning the downstream area.
