Hamm's Holiday Harbor in Chillicothe offers one of the few deep-water harbor facilities along this section of the Illinois River. Located at 16106 N Holiday Harbor Lane, the marina features a protected basin accessible via a narrow channel marked by green and red buoys—exercise caution when entering, as depths can shallow to 5 feet in the approach. The facility includes covered and open boat slips, fuel dock access, and a 36-ton travel lift for haul-out services.
The Illinois River at this location is a major waterway with significant flow characteristics: expect an average current of 4.3 feet per second and flows around 27,000 cubic feet per second. With a gentle average gradient of 0.3 feet per mile, this section is suitable for motorboats, canoes, and kayaks, though paddlers should respect the current and plan accordingly. The area is within walking distance of local restaurants and amenities, making it a convenient access point for day trips or longer river expeditions.
