“One of the nicest trails in the Chicago Area.”— Matthew Rodriguez
The logged trail begins at the Swallow Cliffs - South forest preserve. It begins near the Brown Trail, but this loop follows the yellow blazes for its remainder. The trail crosses several creeks via bridges. Smaller streets are crossed, but for US-45/Lagrange Road, the trail passes through an underpass. After periods of substantial rain, there may be standing water in these underpasses.
In warmer months, proper precautions should be taken for mosquitoes and ticks. Poison ivy is found just off the trails.
