When you take the ferry from Virtsu, the mainland, you arrive to Kuivastu. Kuressaare is approximately 75 kms from Kuivastu. Follow the main road through the centre of Kuressaare until you reach the castle park. At the crossroad turn right (sign pointing to Sõrve) and drive around the park about 250 meters, then turn right (to Veski Street) and find the gray wooden house number 3.
