Plan your daily river and stream crossings.
Most river and stream crossings on the OT are completely safe. Some large rivers have bridges, and other smaller streams can usually be waded without any problems.
However, during periods of heavy rain, some rivers and streams can become dangerous to cross, even at low-water crossings or bridges. Use caution and wait if the water level is too high or the current is too strong. Creeks usually subside within a few hours or a day.
You can also bring sandals to make wading easier and keep your shoes dry.
NAVIGATION: MAPS AND APPS
The OT is generally well marked with blue lights and trail markers. Mile markers are arranged from west to east (Oklahoma to Arkansas) and this is also generally the more popular direction to hike.
Despite the many markers and signs, the trail is overgrown in many places and, if it is covered with fall leaves, it can be difficult to find. Therefore, it is important to always have a map with you.
Guthook Guides (iOS & Android) or Arkansas Hiker (Android only) are two of the most popular hiking apps in the OT. The Guthook and Arkansas Hiker apps are usually accurate, up-to-date, and include waypoints for shelters, trailheads, trail junctions, and water sources.
Note that this changes along the way, but Verizon seems to have the best coverage.
