Nightclubs and bars in Hiiumaa

Although you'll be able to find several bars and clubs in the towns on this island, my suggestion would be - build a nice little fire (using your common sense and following safety rules), barbeque some saussages, sit around the fire (preferably with people you care about), sing songs, talk, listen to the waves and look at the stars and the moon. This is the absolute number one activty you can do in a quiet and peaceful place like this.
