Ron Seman, a dedicated trail leader known for his extensive work guiding hikes through Indiana Dunes State Park, passed away unexpectedly in his sleep at his home in Chesterton. He was 64. Seman’s family reported his death occurred late Thursday or early Friday.
Seman had led a strenuous 16-mile “monster” hike through the dunes the day before Father’s Day. The following day, he experienced what he thought was indigestion. After seeking medical attention at Franciscan Health Michigan City on June 22, he was diagnosed as having had a heart attack and received a stent before being discharged. Seman later shared a message on social media stating he was feeling better and expressed gratitude for the support he had received.
A lifelong enthusiast of the Indiana Dunes, Seman’s passion began in childhood when his family, lacking a car, would bike to the dunes for day trips or camping. After a successful career in computer technology, he moved to Chesterton and started frequenting the dunes daily from 2005 onward, often accompanied by his golden retriever, Aslan.
His interest in local plant life led him to pursue answers for questions posed by fellow hikers. Around 2016, he began organizing group hikes to share his knowledge and love of the area. Seman estimated he guided approximately 4,000 people annually on these outings, which attracted a diverse range of participants—from rural farm residents to urban high-rise dwellers.
Seman’s hikes were more than just physical challenges; they fostered community and personal growth. He often emphasized the therapeutic benefits of nature and organized weekly hikes for individuals in recovery. His wife, Susan Seman, recalled that Ron believed nature had the power to heal a variety of troubles.
In addition to leading hikes, Seman sometimes held informal “Church on the Trail” gatherings, where he discussed spiritual topics with participants. His regular hikers praised him for his kindness, accessibility, and ability to bring people together. Tiffany Yorek of Chesterton, a frequent participant, recounted Seman’s attentive nature and recalled an incident where he quickly transported her to a hospital during a medical emergency, even though he had another hike to lead shortly afterward.
Seman was known for his tireless enthusiasm, often venturing out in rain or snow, adhering to his belief that “There is no bad weather, there are just ill-prepared hikers.” His constant presence on the trails, active social media engagement, and warm personal interactions helped create a vibrant community around the Indiana Dunes.
He is survived by his wife, Susan, his son Christian, and his daughter-in-law. Funeral arrangements have yet to be announced. Seman’s legacy endures in the many people he inspired to appreciate and protect the natural beauty of the Indiana Dunes.
