Treaure Island, Washington

Take State Route 3 to Allyn. Just south of Allyn, turn on Grapeview Loop Road. Turn left if you are coming from the north (from Belfair). Turn right if you are coming from the south (from Shelton).

Follow Grapeview Loop Road approximately 2.7 miles and then turn left on Treasure Island Road. In about .1 of a mile, you will see the one-lane bridge to the island. Wait for the green light and then drive across onto the island.

The paved road that circles the perimeter of the island is called Treasure Island Drive. Some residents still use the original lot numbers (for example, lot 9) when referring to their property. However, all lots should have a posted house number (for example, 1510).
