“Portland Arch should be the Mt. Rushmore of Indiana nature preserves,” said Cliff Chapman, President and CEO of the Central Indiana Land Trust (CILTI). “It’s got it all in one little spot.”

Spring, summer, fall, or winter, this preserve is bursting with interesting topography, plants, and history. From legends about Tecumseh and Lincoln to botanist Charles Deam’s explorations of “Bear Creek Canyon,” the history of the former resort and later Boy Scout camp reflect centuries of attraction to this unique area. Portland Arch is a true Indiana treasure.

The North and South Trails each begin at a parking lot. Both trails are moderately rugged. When wet or snow-covered, several spots can be especially slippery. In addition to the arch, the views are spectacular from the bottom of the canyon.

Winter is a great season for a view of the preserve’s topography. Sandstone cliffs, native pines, the microclimate canyon, and an abundance of biodiversity allow for hours of discovery. Even in winter, green dots the landscape. Visit in spring when wildflowers adorn the landscape.

Coming to a hilltop expanse of white oak trees, Chapman came close to dancing. “You just want to go in and Julie Andrews,” he exclaimed. The majestic stand, dotted with a few black oak and shagbark hickory trees, is a reminder of the value of preserving Indiana’s natural heritage.


Portland Arch was named a National Natural Landmark in 1973 by the National Park Service. Birding is a popular activity at the preserve. Two hours is enough time for a quick walk on both trails, or you can spend hours on each trail, soaking in the beauty of any season.
A guided hike is another great way to learn about the unique biodiversity and history of the property.
