One of the most authentic experiences I love about Finland and Finnishness is a proper cottage experience. The best Finnish cottage is kind a rough and simple cottage in the middle of nowhere on the shore of lake or sea. You should not be able to see your neighbors to be fully relaxed.
The best moments about being on the cottage are the evenings and nights on the warm summer nights when the sun does not set at all. You can sit on the porch with your friends and family all night and complain about mosquitos and how those creatures are the most useless things in the whole world. You can also just sit there quietly and sip your drinks and just listen the sounds of the nature. It is almost enchanting to do that, the longer you do are quiet the more sounds of nature you will hear.
To have a full Finnish cottage experience, sauna and grilling must be included in equation. After sweating in wood cottage sauna, a freshening dip into lake is on point. And again, the porch is playing major role also in sauna experience. You will come out, sit on some bench, and have a conversation like this; “Phew, the wood sauna is something else”. After that you put fire in the grill and grill sausages or something else easy to eat.
For me, these cottage experiences are must haves at least couple times in summer. It brings me to origin Finnishness, own peace, the most important people around you, surrounded by nature and calmness in your heart and soul.
