On the island of Mussalo, Santalahti has a huge range of cottages and conifer-shaded campsites. Shoreline and forest nature trails (each 2.5km long) weave through the property. Bikes and stand-up paddle boards are available for hire. Don't miss the unique 'cave sauna', a smoke sauna with heated pool and fireplace, all in a natural cave facing the glorious sea.
Santalahti is 5km west of central Kotka. The resort offers a shuttle bus (adult/child €3.50/2.20), which runs into town up to three times a day in season.
