Hidden Valley Park borders the Grand River. Owned and managed by Lake Metroparks, Hidden Valley has a river trail and 
many recreational amenities. One of the most popular activities emerging is steelhead fishing. 

Though not native to the Great Lakes, steelhead have been stocked in the eastern United States for more than a century. 
The Ohio Department of Natural Resources, Division of Wildlife, has stocked tributaries in northeast Ohio for a few 
years. In the fall, these fish gather at the river mouths, waiting for the river to rise. They swim upstream to spawn 
and make the return trip in the spring. 

River banks are some of the best places to witness geological finds. Deposited 360 million years ago when much of the 
earth was covered by a shallow sea, Chagrin Shale is a blend of fossilized mud and siltstone that washed into the sea 
from nearby shores. The shale erodes more easily than the siltstone, creating ridges of siltstone protruding from the 
banks. Chagrin Shale is visible at Hidden Valley Park.
