An island playground, a boat ramp, a neighborhood sandbox and a century-old ballpark, with hours, shelters and dog rules sorted.
A castle-themed playground on a Rock River island, a boat launch on the water and a sandbox on West Green Street make up the heart of Watertown WI parks. Four Watertown parks anchor a day out: Riverside Park on the island, Fanny P Lewis Park on the water, Lincoln Park for the playground and Washington Park for baseball. Google lists all four open daily from early morning until 11 pm, and all four as good for children, with an accessible entrance and parking.
Fanny P Lewis Park is about 0.3 miles north-northwest of the center of town, Riverside Park about 0.6 miles east-northeast and Lincoln Park about 0.6 miles northwest, while Washington Park is about 0.9 miles south-southeast.

No two of them sit more than about 1.5 miles apart, and the sections below take them in turn. For the rest of town, start with the Watertown's other attractions.
Riverside Park: the island park on the Rock River
The Watertown Historical Society dates Riverside Park to 1910, when park commissioners decided to lay out a new park on an island in the former Kussel farm, with a rustic bridge to the mainland and a bathing beach planned. The Fannie P Lewis Park Fund agreed to pay half the cost, and the park later gained a swimming pool dedicated in July 1942 and a band shell dedicated in 1954.
The city's Together We Build campaign aims to bring an inclusive recreation area to Riverside Park, designed with the firm Parkitecture, and in December 2025 the city said about $800,000 had been raised toward a $1.9 million cost. The Watertown Daily Times reports that the plan includes play areas for various age groups, accessible surfaces and a patio with games and lounge space.
On Tuesday mornings the Watertown farmers market sets up at Riverside Park, and the Watertown Daily Times reported on May 5, 2026 that it had opened for the season with 11 new vendors. The newspaper says the market has met on Tuesdays since 1860, so confirm the season dates with the market before you plan a visit.
Fanny P Lewis Park: fishing and kayaks off North Water Street
Fanny P Lewis Park sits on North Water Street on the former site of Klink's ice house and beer distributorship, and the historical society lists sitting areas, a boat launch, parking and trees. The park takes its name from Fannie P Lewis, who died in 1905 and left $10,000 in her will for a fund to maintain and beautify city parks.
Lincoln Park: two playgrounds, a sandbox and a pavilion
Lincoln Park at 510 West Green Street is the neighborhood park of the group, with playground equipment separated for older and younger children, a large sandbox, a baseball diamond, a basketball court and a pavilion. The historical society's baseball chapter records Lincoln Park players on the Boys Baseball School all-star team in August 1953.
Washington Park: Richards Hill baseball and a jungle gym
Washington Park on South 12th Street across from a school began as Richards Picnic Grounds in the Richards Hill neighborhood, a gathering spot as early as the 1860s. The society records a baseball diamond laid out in 1898, the Chicago White Sox against the Watertown Goslings on May 23, 1913, and the Chicago Cubs against the Goslings on September 10, 1915.
Beyond the four: Bentzin Square and Tivoli Island
Downtown, Bentzin Family Town Square opened on May 20, 2023, with a band stage, a paved plaza with table and chair seating, a circular path with a water feature and a green, with the Watertown library at the top of the square. The Rock River Water Trail guide also names Tivoli Island Park, a river park just downstream of the Upper Watertown Dam, and the city's park renovations, reopening April 15, 2025, also covered Timothy Johnson, Union and Clark parks.
Planning: shelters, dogs, kids and parking
To reserve a park shelter, the city takes online requests through RecDesk or you can pick up a paper application at the Parks and Recreation office at 514 South First Street, and its notice says requests for 2026 opened on January 2 for residents and January 12 for non-residents. Other park reservations were first come, first served through 2026, and the office phone is 920-262-8080.
Google marks all four parks as allowing dogs, but posted rules apply, so check the signs for leash and cleanup requirements. Riverside Park lists multiple parking lots, Washington Park lists public parking, and Fanny P Lewis Park has a parking area by the boat launch. For little ones, Riverside's Chamberland playground and Lincoln's two-level playground are the ones for kids, while Washington Park is the pick for a ball game, and Fanny P Lewis Park is the pick for watching ducks and geese.
Whether the day starts with a Tuesday market on the island or ends with a ball game on Richards Hill, Watertown parks reward a little time beside the Rock River.
