In the northern part of Tinos island you will find Kolimbithra beach.
Once you get there, you'll realize that Kolimbithra is not one but two beautiful beaches and their main difference is size. The big one can be characterized by one word: chill. Here you can totally relax by the sea or try out surfing (if the wind is helpful). The small one gathers most people as it is more sheltered and organized with sunbeds and umbrellas.
No matter the bay you choose, Kolimbithra beach has excellent food options, coffee and cocktails, while the naturalist in you will be extremely happy as the area is classified as a biotop, where you can observe birds and small animals.
