This guide reflects current authoritative sources and the main points covered by pages that rank today, while keeping the tone friendly and useful for travelers.

Everglades at a Glance (Quick Facts)

• Where it is: Southern Florida, flowing from the Kissimmee River and Lake Okeechobee south toward Florida Bay. Wikipedia

• Why it matters: The Everglades provides drinking water for more than 7 million people in South Florida. U.S. Geological Survey

• Size: Everglades National Park protects ~1.5 million acres; the greater ecosystem is larger. National Park Service

• Unique globally: It’s the only place on Earth where American alligators and American crocodiles coexist in the wild. USGS

• Biodiversity: Home to 350+ bird species and 36 threatened or endangered species including the Florida panther and West Indian manatee. National Park Service

• Special designations: UNESCO World Heritage Site, Biosphere Reserve, and Ramsar Wetland of International Importance; the park is also the largest wilderness in the eastern U.S. and the largest mangrove ecosystem in the Western Hemisphere. UNESCO World Heritage Centre

• Established: The national park was designated in 1947—the first U.S. national park established primarily for its biodiversity. National Park Service

Map of the Florida Everglades

The green area of the map of the Everglades shows the extent of runoff of three rivers from central Florida.

Any and all of these lands are affected by what we call the Florida Everglades. The underlying water moves at a pace of one-half mile per hour.

The significance of the aquifer surrounding these wetlands cannot be underestimated. The water gives life to the plants, trees, and wildlife for 100 miles south.

Hydrology & “River of Grass” Facts

1. The Everglades is not a swamp—it’s a slow-moving river that once spread ~100 miles long and ~60 miles wide in a very shallow sheetflow toward Florida Bay.

2. Early measurements show sheetflow moving roughly tens of meters per day (about 34 m/day on average), emphasizing just how gently this river moves. 

3. The Everglades’ elevation changes by only a few feet; the slight southward slope is what drives the sheetflow. 

4. Water levels and habitats follow two main seasons: a wet season (May–Nov) and a dry season (Dec–Mar) that concentrates wildlife along sloughs and ponds.

5. Alligator holes act as life-saving refuges during droughts, concentrating fish and providing nesting habitat—alligators are a keystone species here. 

6. The Everglades recharges the Biscayne Aquifer, the region’s primary drinking-water source. 

Habitats & Landscapes

7. The park safeguards nine distinct habitats, including sawgrass marsh, mangrove forests, sloughs, marl prairies, cypress domes, pinelands, and hardwood hammocks.

8. It contains the largest continuous stand of sawgrass prairie in North America. 

9. Its mangrove estuaries are the largest in the Western Hemisphere and a critical nursery for fish, crustaceans, and wading birds.

10. More than one-third of Everglades National Park is saltwater (think Florida Bay and coastal estuaries). 

Wildlife You’ll Actually See (and a Few You Might Not)

11. Crocodiles & alligators share this ecosystem—the only place on Earth where that happens in the wild. Crocs prefer brackish/saltwater; gators favor freshwater. 

12. Birding paradise: Over 350 species of birds use the Everglades, including roseate spoonbills, wood storks, snail kites, herons, egrets, and anhingas. 

13. Florida panther: Only about 120–230 adult panthers remain, mostly in Southwest Florida—spotting one is extremely rare. 

14. Manatees, river otters, bottlenose dolphins (in coastal zones), raccoons, deer, and bobcats are also part of the scene. 

15. Invasive Burmese pythons have devastated small mammal populations; over 23,500 pythons have been removed statewide since 2000.

16. New research and tools—from python challenges to robotic marsh-rabbit decoys—aim to increase removals. 

Conservation, Threats & Restoration

17. The Comprehensive Everglades Restoration Plan (CERP) (authorized in 2000) is a multi-decade federal–state effort to restore more natural flows. 

18. A headline project: raising and bridging parts of the Tamiami Trail (U.S. 41) to let water pass south again—repairing a historic choke point. 

19. The upcoming Everglades Agricultural Area (EAA) Reservoir will store and clean water before sending it south to the park and Florida Bay, helping support the Biscayne Aquifer. 

20. Florida Bay—one-third of the park—depends on healthy freshwater flows; past hypersalinity events harmed seagrasses and fisheries. 

21. Sea-level rise, saltwater intrusion, nutrient pollution, and invasive species remain pressing threats—but restoration is showing pockets of progress. 

People, Place & Identity

22. Long before the park, Seminole and Miccosukee peoples lived in and around the Everglades, shaping and being shaped by the landscape. 

23. In 1947, the same year the park was dedicated, Marjory Stoneman Douglas published The Everglades: River of Grass, cementing the ecosystem’s modern identity.

24. Today, about one million visitors experience the park each year via centers near Miami/Homestead, Shark Valley, Flamingo, and Everglades City. 

Visitor-Friendly Facts (Plan Smarter)

25. Best wildlife viewing: Typically during the dry season (Dec–Mar) when water recedes and animals congregate along sloughs and ponds.

26. Top first-timer stops: Shark Valley (tram, biking), Anhinga Trail (close bird & gator views), Flamingo (manatees, crocs), and the Gulf Coast (Ten Thousand Islands).

27. Safety: Keep distance from wildlife (and never feed). For quick ID: gators have broad, U-shaped snouts; crocodiles are more V-shaped. 

Everglades by the Numbers 

28. 1,542,000+ acres in Everglades National Park. 

29. 36 threatened or endangered species in the park; 350+ bird species documented. 

30. >7 million people rely on the Everglades for drinking water. 

31. World Heritage, Biosphere Reserve, Ramsar designations underscore global significance.

32. Sheetflow speed: roughly dozens of meters per day (varies by habitat and season).

60 More “Fun” Facts About the Everglades

• Origins & Flow – The system’s headwaters begin near Orlando in the Kissimmee River, flowing into Lake Okeechobee before spreading south. 
• Raised roadbeds and canals historically blocked natural flows—today’s bridges and culverts are restoring them. 
• The Everglades’ elevation rarely exceeds 8 feet above sea level—yet that’s enough to create an entire river system. 

Interesting Facts About the Florida Everglades Habitats

• Hardwood hammocks are tree “islands” slightly higher than surrounding marsh, sheltering tropical species at their northern limits. 
• Pinelands grow on porous limestone ridges and depend on frequent, low-intensity fire. 
• Cypress domes form where trees grow taller in deeper center water, creating the dome silhouette. 
• Wildlife
  The snail kite relies on apple snails and is tightly linked to water levels and restoration. 
• Roseate spoonbills act as indicators of healthy estuaries. 
• Manatees often graze in brackish estuaries and warm waters near Flamingo/Florida Bay. 
• American crocodiles are more salt-tolerant and primarily occupy coastal areas near Florida Bay. 
• Alligator nesting helps create peat and even provides nesting sites for certain turtles—one reason gators are considered keystone here. 
• Wading birds’ historic rookeries declined dramatically in the 20th century due to drainage and plume hunting; restoration seeks to rebuild populations. 

Invasives & Management

• Burmese pythons can exceed 16 feet and lay 50–100 eggs per clutch. 
• Contractors and citizen programs (Python Challenge, PATRIC) continue to scale removal techniques. 
• Innovative tools (e.g., robotic rabbit lures) are being tested to improve python detection. 

Restoration & Water Quality

• 

  CERP investments aim to restore timing, quantity, and distribution of freshwater after a century of drainage. 
• The EAA Reservoir will store and clean water before sending it south, reducing harmful discharges elsewhere and improving flows to Florida Bay. 
• Florida Bay health is tied to upstream flows; hypersalinity events trigger seagrass die-offs and fishery impacts. 
• The park’s international designations reflect its status as a global stronghold for wading bird breeding. UNESCO World Heritage Centre

Visitor Essentials

• Four main visitor centers serve typical entry points; hours and programs vary by season—check NPS before you go. 
• Shark Valley’s 15-mile loop is a classic for seeing alligators, anhingas, and herons up close (safely).
  54) The Anhinga Trail is famous for boardwalk birding in the dry season.

• Flamingo is your best bet for crocodile sightings and manatees in winter months. 
• Ten Thousand Islands (Gulf Coast) offers kayaking and boat tours through mangrove labyrinths. 
• Keep 50+ feet from wildlife when possible; never feed animals. (NPS wildlife ethics & safety.)

History & Culture

• The Everglades was long misbranded a “useless swamp” until Marjory Stoneman Douglas’s 1947 book reframed it as a river worth saving. 
• The park’s dedication in 1947 was a turning point in U.S. conservation—biodiversity, not scenery, was the main reason for protection. 
• Restoration today is as much about people and water security as it is about wildlife. 

About Everglades National Park System

There are 5 visitor centers scattered throughout the Everglades National Park. Each is designed to cover a portion of the wilderness and offer assistance to visitors.

The Everglades National Park Visitor Centers are:

The Gulf Coast Visitors Center, in Everglades City.

Shark Valley Visitor Center, along the Tamiami Trail.

Ernest F. Coe Visitor Center, Homestead, Florida

Royal Palm Visitor Center, on Rt. 9336 on road to Flamingo.

Flamingo Visitor Center, Flamingo, Florida, deep in the Everglades.

If you visit all of these visitor centers, you will have seen much of the Everglades. 

(Tip for readers: if you’re road-tripping, the Tamiami Trail is the most scenic east–west crossing for wildlife viewing; I-75 Alligator Alley is faster but less scenic.)
