Hayden Island is home to roughly 2,500 residents who live in condos, standalone homes, an RV park, and house boats. Hayden Island is also known for its several marinas and yacht clubs, local restaurants, the Jantzen Beach Shopping Center, water recreation rental services, and hotels. There are no schools or churches located on Hayden Islands, so residents must leave to find these services. Additionally, most of the developed land is on the southeast part of the island. The northwest part, also known as West Hayden Island, is an undeveloped nature preserve that is not open to the general public.
Finally, Hayden Island is also rather flat, so you and Fido shouldn't have issues running into steep or unwelcome hills in this neighborhood.
Besides Interstate 5 which runs through the island, North Hayden Island Drive is the main road through this community. The major local shopping complex sits off this road, so traffic may be more congested or going at a faster speed. Hayden Island is bordered by the Columbia River on all sides and Tomahawk Island to the southeast.
Lotus Isle Park is a 1-acre greenway with paved paths, a playground, places to sit and rest, and an area for picnicking. This small greenway is an ode to the 128-acre amusement park, named the Million-Dollar Pleasure Paradise, that once took up much of Jantzen Beach and the surrounding area. While the amusement park closed in the 1930s, at least you and Fido have a small green space to explore and enjoy!
Unfortunately, the nearest greenways to the south in Portland are all community centers or golf courses. To the north, in Washington, you will find some smaller, residential parks like Esther Short Park and Playground, Memory-Mill Plain Park, and Marshall Park.
