The fragmentary archipelago in front of Rauma is like made for canoeists. The routes at the inland archipelago go mainly through sheltered coves and straits.
There is a map of the canoeing routes at Rauma archipelago which also shows different rest stops and huts that can be rented.
Santkari lighthouse island is situated in the middle of open sea, and it is suitable only for the most experienced canoeists. It is not recommended for others. You should not go canoeing if it is windy, and the canoeists must be prepared for changes in weather.
There is no marked boat route to Santkari, and the route has not been marked to Raumanmeri – Bothnian Sea map either.
Some canoeists use the route from Kuuskajaskari between Rouna- and Haminakari, south side of Ulko-Kylmä to Louekari and Trutpuda, and still further to Santkari’s east shore. The waters around Louekari, Trutpuda and Santkari are very rocky. It is possible to avoid the rocks with a basic map.
There are natural shores suitable for canoeists at Santkari. There is often a windless region at the cove, and the waves there do not always feel as big as at the west and south sides of the island. There is a buoy to help the canoeists to recognise the place.
Santkari is also a bird island. Do not disturb the birds’ nesting.
