What to know

Jack Block Park is a 15-acre waterfront destination located at 2130 Harbor Ave SW in West Seattle. The park provides a unique vantage point for visitors to observe the daily rhythms of Elliott Bay, including the movement of ferries and shipping traffic. A shoreline walking path leads visitors past a children's play area and a walkable pier, eventually terminating at a 45-foot-high observation tower that overlooks downtown Seattle, Terminal 5, and the Vigor Shipyards. The site's history is a story of environmental recovery. In the early 1900s, the land was used as a shipbuilding facility and a wood treatment plant. These industrial activities left the area contaminated with creosote, leading the U.S. Environmental Protection Agency to designate it a Superfund site in 1994. Following extensive cleanup work, the park opened in 1998 as part of the Port of Seattle's redevelopment of Terminal 5. Named after former Port Commissioner Jack Block in 2001, the park continues to evolve. While the park itself opened in the late nineties, the beach area only became available for public access in 2011 after further environmental remediation removed contaminated mud and wood pilings. Today, the park blends industrial heritage with public recreation, featuring a nautical theme with marine float sculptures at the entrance and big-ship pier ties scattered throughout the grounds.

Visitor tips

  • The park is open daily from dawn to dusk, so plan your visit for daylight hours.
  • Utilize the accessible route from the parking area to reach the observation tower and restrooms.
  • Visit during peak shipping hours to see the most activity at Terminal 5 and Vigor Shipyards.
