Spend the morning hiking and exploring the Hidden Hollows of the Grand River. We’ll visit two special properties, one open to the public and one private, to explore the unique microhabitats that persevere in these special hollows of the Grand River gorge areas. The isolated and rough terrain of these hollows protected them from the saw and made one of them a local stop on the underground railroad. Afterwards, we’ll head to a near by tavern for lunch. (Optional-not included in fee). Moderate/difficult, walking off trail on hilly terrain.
