Aside from pleasure craft docks and a fueling facility, the park also has walking paths and a boardwalk, playground equipment, picnic tables, a Mariner's Monument[1] and the historic CN Rail Station (now home to gift shops and ice-cream parlor, restaurant and other amenities).

The private company is in the process of building two seven-story condos, an art gallery and a hotel with a water park onto the marina.

The current area is being infilled by an average of 3 acres (12,000 m2) between each pier to create enough room for the new buildings.

The park also hosts numerous events during the summer season, including the "Summer in the Parks" concert series,[3] the Thunder Bay Blues Festival,[4] kite festival, Canada Day celebrations and many other annual events.

The Prince Arthur's Landing waterfront district is a mixed-used waterfront redevelopment district incorporating the city's Marina Park, with parkland and trails, a sculpture garden, restored heritage buildings and a future hotel.
