Places We Protect

Cypress Island Preserve


Discover the Cypress Island Visitor Center, exciting wildlife viewing, and boardwalk.


Beginning in late January, thousands of Great Egrets, followed by Little Blue Herons, Cattle Egrets, Snowy Egrets and Roseate Spoonbills make their nests and rear their young in the rookery. Great Blue Herons and Neotropic Cormorants may be seen in the distant tree tops. Expect a spectacular rookery view from March through June. The 2.5-mile walking levee trail is open from the fall to the spring and is suitable for children. Because this remarkable natural area is easily accessible and affords visitors with incredible wildlife viewing opportunities, our Cypress Island Preserve receives thousands of visitors a year from all over the world. Please visit our boardwalk and Visitor Center with picnic pavilion where Rookery Road meets LA Hwy 353.

The Visitor Center is generally open from 10:00 am until 4:00 pm on weekends year-round and during the week from Wednesday through Sunday during the busy springtime. Please call first for current hours at (337) 342-2475. Please contact us if you are interested in volunteer opportunities at the preserve, including working with a team of docents to staff the Visitor Center. 

What the Conservancy Is Doing

The Nature Conservancy of Louisiana's goal is to restore 20,000-acres of natural cypress-tupelo swamp and bottomland hardwood forest, in order to support a diverse array of indigenous species of plants and wildlife. We offer a community gathering place and education about the natural wonders of Louisiana in the Visitor Center.

The Visitor Center is staffed by volunteer Docents weekend days from 10:00 am until 4:00 pm all year round and from Wednesday through Sunday during the busy springtime. We are often open during the week, but please call before your visit to make sure. The preserve is open during daylight hours. The walking trail starting along the levee is closed during alligator nesting season, June through October. The rookery area in the southern end of Lake Martin is closed to all boat entry from February 1 through July 31 for breeding bird season. You may drive along Rookery Road all year round.

What to See: Plants

This cypress-tupelo swamp and bottomland hardwood forest habitat is a relic of the mysterious swamps of the past, with old-growth live oaks and cypress covered with Spanish moss.

What to See: Animals

The preserve is home to a spectacular wading bird rookery that supports thousands of nesting birds each spring. Nesting White Ibis, Anhinga, Cormorant, Snowy Egret, Little Blue Heron, Green Heron, Great Egret, Roseate Spoonbill, Tri-color Heron, Yellow-Crowned Night Heron, Black-Crowned Night Heron, and Great Blue Heron may be observed. The walking levee trail on the preserve is also a superb place to observe trans-gulf migratory songbirds. As you visit the preserve, keep an eye out for the many reptiles and amphibians that call this area home, including all sizes of American alligators.
