This is a great weekly workout hike.
You can hike about half way up, to the Welsh Woods picnic area and back (about 2.5 miles) or the entire length of the park and back - 5 miles.
To get to the park, take I-90 to E. 185th Street; exit south. E. 185th becomes Nottingham, and after you cross Euclid Ave. (approx. 1/2 mile) it becomes Highland Rd. Euclid Creek Reservation will be on the right. Turn right onto Euclid Creek Parkway, then turn left into the Highland Picnic Area parking lot.
If you click on Cleveland Metroparks above, you will be able to click on Directions and enter your starting point for directions.
I originated this particular hike to be a WORKOUT* hike, and have described it as such. If you prefer to "stroll," that's fine; the paved trail in this park is a linear trail alongside the creek all the way, so you don't need to worry about getting lost.
*Workout: a session of vigorous physical exercise or training.
