Sisä-Hattu

Sisä-Hattu is a small rocky island in the Baltic Sea, situated approximately 100 meters from the shore near Lauttasaari recreational park in Helsinki. The rock rises from the water and consists of gray stone shaped by elements and time.

The rock was marked by visitors in the 1940s with carved inscriptions, who etched names and dates into the surface. These markings show the long history of people who have explored and visited this location.

For people in Helsinki, this spot represents a place to experience the sea's proximity and spend time outdoors. Locals come here to fish or simply sit on the rocks and enjoy the surroundings.

The island is only accessible at low tide, when the water recedes enough to reveal a submerged path. Visitors should wear shoes with good grip and check the tide times before making the approximately 50-meter crossing.

The water level around the island changes daily, which means the submerged path shifts between being clearly visible and barely reachable depending on the tides. This creates a constantly changing character of the place that responds to the sea's natural rhythm.
