Right at the beginning of the Accotink lake trail, this small creek has a nice semi paved trail with a good looking sturdy bridge. Great location for nature hiking, bird watching and biking.

MTB section of the Accotink loop trail, this part has some roots exposed but any MTB bike can handle them, some nature hikers around so mind your speed around turns. Some sections of the trail will let you stop for a quick lake photo.
