There are four Alpine botanical gardens in the Aosta Valley evidence of the awareness and intention to preserving the natural heritage and, in particular, in protecting the floristic heritage:

  • Chanousia garden, at the Little St Bernard pass, in the La Thuile area
  • Saussurea  garden at the Pavillon station of the Skyway Monte Bianco cable car, in Courmayeur
  • Paradisia garden in Cogne-Valnontey and in the Gran Paradiso national park
  • Castel Savoia garden in Gressoney-Saint-Jean.

These Alpine botanical gardens offer the naturalist a useful research tool while offering the visitor the chance to discover the characteristic mountain environment and alpine flora.
