Mellsten Beach is a popular public beach in Haukilahti, with sand, summer lifeguards, and a cafe for food and drinks. It is a straightforward local beach, but a good one, especially if you are staying in Espoo and want a swim without heading into Helsinki.
The beach is also known as a windsurfing spot in the capital region. Toppelund Beach lies a short walk east, with fewer services and a quieter feel.
