Forest bathing (Shinrin-yoku 森林浴) developed in Japan during the second half of the 20th Century. The practice consists in relatively short and easy hikes through forests.
I've found forest bathing to be similar to the more famous custom of the Japanese bath: both are a medicine against the hardships of everyday life.
This is an ongoing project: I'm bathing in the same forest across the four seasons. Certain subjects remain the same, albeit photographed from a slightly different point of view.
