Euclid Creek passes beneath Cedar Road to enter the Acacia Metropark, one of the Cleveland Metroparks located in Lyndhurst, Ohio, in the United States.

The United States Geological Survey places the headwaters of the main branch of Euclid Creek between Fairmount Blvd. and Fairwood Court in Beachwood, Ohio (about one mile due south of the entrance to the park). The Division of Surface Water of the Ohio Environmental Protection Agency places the headwaters on the Acacia Reservation just before the creek leaves the park for good. (This about 545 feet due west of Acacia Trail, just after Euclid Creek reenters the park briefly.)

Using the southern headwaters, the creek travels just under 1.5 miles (east of I-271, north along I-271, threading through Monetfiore and Menorah Park, then west along Cedar Road) before passing under Cedar Road via a culvert to reach Acacia Reservation.

Here the creek finally finds rest, in a natural setting.
