Leksand Sommarland is the town's main family attraction in summer, with water slides, go-karts, rope courses, laser tag, and small roller coasters. It is aimed squarely at children and families rather than sightseeing travellers.
For families staying around Lake Siljan, it can easily fill most of a warm day. For everyone else, it is mainly useful to know why Leksand gets busier during the Swedish school holidays.
