Two tour options are available: The trail is 0.6-mile from the trailhead to the tree (1.2 miles round trip) through a bottomlands forest.   The trail is level, and has several stretches of boardwalk over seasonal marshes.   Marshes are common in April when spring rains encourage flowers such as irises to bloom.   There is a rich diversity of plants, birds and evidence of mammals to see in this forest wetland.   Binoculars, sunscreen, and mosquito repellant are recommended.

At the end of the trail, visitors will arrive at the San Bernard Oak, formerly designated by the Texas A&M Forest Service Big Tree Registry as the largest Live Oak (Quercus virginiana var. virginiana) in Texas. As of 2016, the criteria for this designation was revised and this distinction was awarded to a Live Oak in Colorado County.
