Due to the sensitivity of the habitats and the endangered species, the refuge is not open to unsupervised use by the public. However, refuge staff and local educators conduct on-site environmental education efforts through special events and monthly guided tours, typically the second Saturday of every month. Volunteers also regularly assist refuge staff with habitat restoration projects and endangered species surveys.
