Finland has several popular winter and summer activities. Ice hockey is the national sport and is played by children in schools. Other winter activities include frisbee golf, which uses frisbees instead of balls and clubs on a course with targets, and skiing/snowboarding in Lapland. In summer, Finns enjoy time in lakeside cottages and relaxing in saunas, which are found in most homes. After sauna they may relax in an outdoor hot tub called a palju.
