Mandalay National Wildlife Refuge, National Wildlife Refuge in Terrebonne Parish, United States.

Mandalay National Wildlife Refuge covers 4,619 acres of freshwater marsh and cypress-tupelo swamp in Terrebonne Parish, about 5 miles southwest of Houma. It is one of eight refuges in the Southeast Louisiana National Wildlife Refuge Complex. The marsh is soft enough that foot travel is extremely difficult; boats are the way in.

Mandalay National Wildlife Refuge was established in 1996 in Terrebonne Parish, 5 miles southwest of Houma, as one of eight refuges in the Southeast Louisiana National Wildlife Refuge Complex. Its 4,619 acres of freshwater marsh and cypress-tupelo swamp were set aside as habitat for waterfowl, wading birds and neotropical songbirds. The Friends of Louisiana Wildlife Refuges, a non-profit membership group, supports the complex through grants, fund-raising and weekend volunteer work days.

The refuge is managed within the Southeast Louisiana National Wildlife Refuge Complex, one of eight refuges in the group. The Friends of Louisiana Wildlife Refuges, a non-profit membership organisation, sponsors several of the refuge's annual events, obtains grants for refuge projects, raises funds for environmental education and runs weekend volunteer work days to help the Fish and Wildlife Service maintain facilities and programmes.

Visiting the refuge requires a boat, as there is no road access to the interior and it can only be reached by water. It helps to go with someone familiar with the waterways, as the channels and routes can be confusing for first-time visitors.

The refuge covers 4,619 acres of freshwater marsh and cypress-tupelo swamp, and foot travel is extremely difficult because the marsh ground is so soft. Access is by boat only, so most visitors see the waterfowl, wading birds and neotropical songbirds from the water.
