A large portion of the trails are usable to most visitors.
As you come in on the raised boardwalk you will encounter bridge 1 on your left; on the other side of bridge 1 is the beginning of the trail. This trail is usable.
The raised boardwalk provides visitors with a fully accessible route to the Gift shop and Cafe. Both of these facilities are fully accessible.
Although the bridges are accessible, if you proceed past them onto the loop trail you could experience uneven terrain caused by wear and roots under the asphalt. These trails are usable. Please be cautious as you proceed.
