The technicality of the Biology Trails at White Oak range from easy to extremely difficult and are most appropriate for intermediate to strenuous and technical. It offers a stacked loop system, with the easiest trails closest to the parking lot and the hardest trails further away. Expect lots of roots, rocks, and pebbles offering poor traction on most trails. The trail system drains VERY well, which makes it a great option directly after a rain. The top of the ridge is the rockiest, most technical section, but it also offers incredible views into the Ooltewah valley. It’s also a great location for night rides in the winter since the trails stay open until 10 PM daily.
