10 beautiful nature paintings from various painters.
While not being able to go outside as much as I'd like to, looking at paintings of some of my favourite areas and painters help. Here are 10 beautiful nature paintings.

Ferdinand Hodler, Lake Thun.
Easily my favourite painter. Painted in many of my favourite areas such as Maloja, Geneva, Lake Thun. Wonderful colours and reflections. Some of Hodler's mountains and lakes are hanging in my apartment.

Giovanni Segantini, Spring in the Alps.
Another favourite of mine, who was originally Italian but painted many landscapes in Switzerland as well. The Segantini Museum in St. Moritz is worth visiting.

Katsushika Hokusai, The Great Wave off Kanagawa.
A very different world, but always calming to look at. My favourite piece of Japanese art (and I'm sure I'm not the only one with that choice).

Augusto Giacometti, Blue Mountains.
The cousin of the father* of world-famous sculptor Alberto, Augusto Giacometti was a painter and daily known for his work with stained glass (especially for church windows). I like some of his paintings, which are often making use of unnatural colours.

J. M. W. Turner, The Dark Rigi: The Lake of Lucerne.
This Romantic painter created many dramatic images, especially often depicting water. His paintings from his time in Switzerland are some of my favourites because they include more mountains.

Caspar David Friedrich, Winter Landscape with a Church.
My favourite German painter, who - like many Romantic painters - loved nature and landscapes. Often, humans are added somewhere to show them in awe of nature, such as in "Wanderer above the Sea of Fog".

Cuno Amict, Depiction of a Garden.
A Swiss artist who often painted gardens and harvests, such as on this beautiful painting. His numerous self-portraits are not that interesting to me, but his landscapes are always vibrant and colourful.

Claude Monet, Water Lilies.
There are numerous garden and pond paintings by Monet, and I love all of them. The colours are so wonderful and soothing. This French artist was the father of Impressionism, which derived its names from one of his paintings.

Vincent Van Gogh, Landscape with Olive Trees.
This Dutch painter lived in France for a long time and captured the beauty of the French landscapes. Besides his sunflowers, I especially like his olive trees.

Giovanni Giacometti, Winter Sun in Maloja.
Another Giacometti, this is the father of the most famous Giacometti Alberto. Spent much time in Bregaglia and Maloja, so many of his paintings show these beautiful areas.
PS Many museums offer visual tours of their art, for example these:
