Sabal Palm Sanctuary, Protected nature reserve in Cameron County, Texas.

Sabal Palm Sanctuary is a 557-acre (225-hectare) nature reserve and bird sanctuary in Cameron County near Brownsville, Texas, at the delta of the Rio Grande Valley. It protects one of the last groves of sabal palms in the valley, with about 5 miles (8 km) of signed trails through the palm grove, an oxbow lake turning into a wetland resaca, a butterfly garden and the river shore.

The site originated as a sugarcane plantation from the 19th century, complete with a Victorian mansion built during that era. That historic house now operates as the visitor center and serves as a reminder of the land's earlier use.

The sanctuary keeps the name of the sabal palm, whose edible heart was prized by pre-Hispanic inhabitants and noted by early explorers. The Rabb family's 1891–1892 Queen Anne mansion, remodeled in 2013, now serves as the visitor center, so a building from the sugarcane era frames the entrance to the palm grove.

The best time to explore is early morning when temperatures are cooler and wildlife is most active. Wear comfortable walking shoes and be prepared for wet areas along the trails, as well as insects in warmer months.

More than 300 bird species use this area, including rare types that are difficult to spot elsewhere in the country. The location serves as a critical stopover point during migration seasons, drawing many ornithologists and birders.
