High Alps

High-elevation alpine diving in small mountain lakes and artificial reservoirs used for hydroelectric power.

The Swiss High Alps offer a very different freshwater diving experience: cold, high-elevation lakes surrounded by steep mountain terrain. Many of these waters are relatively small, and a large part of accessible sites are artificial reservoirs built for hydroelectric energy production.

Why dive in the High Alps?

  • Dramatic mountain scenery above and below the surface
  • Unique high-altitude diving conditions
  • Quiet and little known remote site

What to consider?

  • Most dives require drysuit and proper thermal protection all year
  • Altitude affects dive planning, so use altitude-aware tables or computer settings
  • Conditions can change quickly because of weather in the mountains
  • Reservoir water levels may vary due to energy production and season
  • Access roads, parking, and entry points can be limited in remote valleys
  • Diving artificial waters used for energy production requires official consent
