Anhinga Trail, Educational trail in Everglades National Park, Miami-Dade County, US.

Anhinga Trail is a roughly 0.4-mile (about 650 m) loop in Everglades National Park that starts at the Royal Palm Visitor Center, 4 miles from the park entrance. It first follows a stretch of the former Old Ingraham Highway, then leaves it after about 400 m and crosses Taylor Slough, a freshwater sawgrass marsh, on wooden boardwalks that curve back to the old road. Several observation platforms along the way are used for watching alligators and birds such as the anhinga.

The trail follows part of the Old Ingraham Highway, the former road from Florida City to Flamingo, replaced by the current park road in the 1960s and since open only to walkers and cyclists. It was listed on the U.S. National Register of Historic Places on November 5, 1996.

The trail follows part of the Old Ingraham Highway, the former road from Florida City to Flamingo, replaced by the current park road in the 1960s and since used only by walkers and cyclists. The anhinga, or snakebird, gives the trail its name; viewing platforms along the boardwalk are set up for watching it and the alligators.

The loop starts at the Royal Palm Visitor Center parking area, reached by a turnoff a few kilometres past the park entrance from Florida City. The first stretch follows the former Old Ingraham Highway, then boardwalks curve through the marsh; allow about 45 minutes with wildlife stops. The 600 m Gumbo Limbo Trail also leaves from the same parking area.

In 2003 visitors watched an alligator fight a Burmese python for 24 hours on the trail; a larger alligator joined and the snake escaped. Video of the fight spread widely and drew attention to pythons as an invasive species in the Everglades.
