Muriel Iverson Williams Poulsbo Waterfront Park and Kvelstad Pavilion
On Poulsbo's waterfront is a lovely park with lawn, walking paths and a large gazebo with some seating surrounding it. You'll find plenty of benches to sit and look out at the marina.
The park's namesake, Muriel Iverson Williams, was the town's second mayor.
While you're in the park, look for the small statue of Viking King Olaf near the Sons of Norway, and the Guardian Stone statue (swords in the stone!) And be sure to take a walk down the nearby boardwalk which will take you to some trails into American Legion Park.
If you're a birder, you'll find many marine birds and some other varieties. I've noted many great blue herons, several varieties of duck, occasionally I've spotted a belted Kingfisher -- though I think I recall that being closer down near the Fish Park bridge. Canada geese, of course, and many gulls. You also might spy a bald eagle or osprey but at this location they're usually farther overhead.

Sucia Island
Transporation to Sucia is boat-only. If you don't have a boat of your own, Outer Island Excursions runs a water taxi and will (for an extra fee) bring along your ebike or kayak or let you rent one. There's also some camping spots on the island.
Whale Watching
You may see orcas, humpback whales, or just have a lovely boat ride.
