Parque Maria Behety is one of Punta Arenas' main green spaces, useful when you want a break from the wind and the hard edges of the port. It has picnic areas, a lake, and enough space for a slow walk away from the centre.
In summer the lake is used for canoes and kayaks; in a cold winter it can freeze into an informal skating spot. It is not a headline sight, but it is a good local park if you are spending more than a day in town.
