With beautiful, glacial-relic stands of eastern hemlock and Canada yew flourishing on cool, north-facing slopes, it’s no surprise that Big Walnut was dedicated as a state nature preserve in 1985. Exceptionally large trees, including the largest known hemlock trees in Indiana, are scattered across the preserve along with one of the few remaining stands of a beech, sugar maple, tulip, poplar climax forest growing in west-central Indiana.
Spring brings a carpet of wildflowers including spring beauties, anemones, Virginia bluebells, and large-flowered trilliums, and the emergence of cerulean, worm-eating and hooded warblers and great blue herons. The rare-plant seekers won't be disappointed at Big Walnut either; eastern hemlock, Canada yew, Clinton's woodfern, Goldie's fern, and bristly sarsaparilla—among other uncommon plants—can be found in this amazing preserve.
During the summer, the forests of Big Walnut offer a cool retreat from the urban heat.
As fall approaches, the summer colors fade to red, orange and gold. Once the leaves fall, Big Walnut is still entrancing, and you may find yourself the only one in the forest.
When winter arrives, snow and ice blanket the area, making it a welcome respite for visitors seeking the peace and quiet of the season.
Many of our preserves allow deer hunting from October through the first week of January, so wearing blaze orange is suggested when hiking in these areas during hunting season.
