Places of interest within an hour of Lafayette.
To the west:
The Potholes, about 45 to 60 minutes depending on your route. Owned by the Nature Conservancy, the Potholes (link) is one of the most unique natural areas in the state. Etched sandstone holes in a sandstone ravine are the source of the nickname. Formally known as Fall Creek Gorge, Fall Creek feeds into scenic Big Pine. Although Big Pine is too low to canoe this time of year, a ride along the stream is time well spent as a scenic drive. Free.
Leaving the Potholes to the south is Williamsport Falls, the tallest waterfall in Indiana (link). Free. Not much water right now, but similar sandstone carvings to the Potholes. Take the back road from Williamsport to Portland Arch for a beautiful scenic drive.
Portland Arch, about 45 minutes from SR25 and US231 going through Attica to US41. This is nature preserve overseen by Indiana DNR, but is a national natural landmark. (link) This nature area is a bit different from the Potholes, showing the progression of the glaciers in Indiana. Free.
To the east:
Adams Mill, about 35 minutes from I65 and SR26. Adams Mill dates back to 1845 and is the 3rd mill on the site. There are weekend hours for the museum in the mill. Fee charged. (link) Adjacent to the mill is the Oxbow Nature Area and the C.J. Baker Memorial Trail (link). The DNR Fish and Wildlife Div. owns land across the road providing access to the North Fork of the Wildcat Creek. The mill is on both the yellow and red Carroll County scenic routes (link).
