Newcastle Beach Park is the largest beach park in Bellevue, Washington, spanning 28 acres along the eastern shore of Lake Washington. It features a 300-foot sandy swimming beach monitored by lifeguards during the peak summer season. The park provides extensive amenities including a playground, horseshoe pits, and a public fishing pier. Visitors can access a network of trails that connect to the broader Bellevue park system. The park grounds include open grassy areas and picnic sites with BBQ grills. A unique feature is the park's designated swimming area which is separated from motorized watercraft. It serves as a primary access point for both shore-based recreation and non-motorized water activity on Lake Washington. The facility is equipped with permanent restrooms and changing rooms. Parking is provided in a dedicated lot adjacent to the park entrance.
The end of the fishing pier offers a panoramic view looking west across the lake toward the Seattle skyline.
Arrive early on warm weekends as the parking lot frequently reaches capacity by mid-morning.
Bring water shoes if you plan to swim, as the lake bottom near the shore can be rocky.
Check the official city website for current water quality advisories before swimming.
Do not attempt to park on Lake Washington Blvd SE if the lot is full, as this is a high-traffic road with limited shoulders.
Lifeguards are on duty only during the summer season; swimming is unsupervised at other times.
No alcohol is permitted on park grounds; dogs must remain on a leash at all times and are not permitted on the sandy beach area.
