Ottawa Beach, Public beach in Ottawa County, United States.

Ottawa Beach is a beach in Ottawa County, Michigan, on the shore of Lake Macatawa, which connects to Lake Michigan. The source places it about 900 km southwest of Washington, D.C., in a hemiboreal climate where August averages 20 °C and February averages −13 °C.

This location came into use during the early 1900s when residents discovered the recreational opportunities offered by the shoreline. Over time it evolved from a simple access point into a managed beach facility with permanent infrastructure.

Ottawa Beach lies on Lake Macatawa, which drains into Lake Michigan through a channel at Holland. The beach takes its name from the Ottawa, the Indigenous people of this part of Michigan. Summer visitors swim, picnic and walk the water's edge, and the surrounding Ottawa County shoreline draws people from the Holland area.

The beach remains easily accessible during warm months and provides ample parking along with designated swimming zones. Visitors should check water conditions and weather before entering the lake, as seasonal lifeguard coverage affects safety planning.

Several shore bird species nest in protected areas along this stretch, making spring and summer months particularly rewarding for birdwatchers visiting the site. These species form an important part of the local ecosystem that visitors often discover while spending time by the water.
