The Olentangy River is a 97-mile long tributary of the Scioto River in central Ohio. It originates in Crawford County and flows south through Delaware County and Franklin County before joining the Scioto River in downtown Columbus. The river is part of the larger Ohio River watershed.

Paddling opportunities abound on the Olentangy, with several popular sections catering to different skill levels. The 4.4-mile stretch from Sycamore Run Park to Highbanks Metro Park offers a scenic Class I-II experience suitable for beginners and intermediates. For more experienced paddlers, the 3.7-mile Delaware to Chapman Road section features Class I-II(III) rapids. The Olentangy River Water Trail, an 8.94-mile urban paddle through Columbus, provides a unique blend of natural beauty and city views. The overall difficulty ranges from Class I to II, with some Class III rapids possible at higher water levels. Most sections are suitable for intermediate paddlers, though beginners can enjoy calmer stretches with proper guidance.

Spring and early summer are ideal paddling seasons when water levels are typically higher. Late summer and fall can still offer enjoyable trips, but paddlers should be prepared for potentially lower water levels.

The river corridor supports diverse wildlife, including minks, beavers, and various bird species. Shale banks and wooded areas line much of the route, providing scenic views and habitat for local flora. Key landmarks include The Ohio State University campus, historic Columbus neighborhoods, and several metro parks. The river passes through both rural and urban landscapes, offering a varied paddling experience.

Major access points include Sycamore Run Park in Delaware, Highbanks Metro Park, and multiple locations within Columbus city limits. The Broad Meadows pedestrian bridge serves as the put-in for the urban water trail.

Historically, the Olentangy River played a crucial role in the development of central Ohio. Today, 22 miles of the river are designated as a State Scenic River, recognizing its natural and recreational value.

Paddlers should be aware of several lowhead dams along the urban sections that require portaging. It's essential to check water levels before trips, especially for the more challenging upstream sections. While primarily used for day trips, the river's length and multiple access points could allow for multi-day adventures for those willing to arrange logistics and camping.
