If ever you find yourself in Costa Rica and exploring Lake Arenal, then it is worth stopping by Mystica in Sabalito. They have beautiful accommodation and great food in their restaurant but for me the selling point is obviously the yoga studio.
The studio is tucked around the back of the large site in lush green surroundings and sits on a platform with the river running beneath. The sound of the water is hypnotic and in rainy season makes for a lovely haven with the pitter patter on the roof. For more details visit the website or Facebook
