Venezuela contains Angel Falls, the world's highest uninterrupted waterfall at 979 meters. The Canaima National Park, where Angel Falls is located, received UNESCO World Heritage designation in 1994 and covers 30,000 square kilometers of the Guiana Highlands. The tepuis, table-top mountains formed from sandstone over two billion years old, create ecosystems isolated from ground level for millions of years. The fall was measured and documented by American aviator Jimmie Angel in 1933, though indigenous Pemón people knew it as Kerepakupai Merú for centuries before. The water drops from Auyán-tepui in a single plunge so high that much of it converts to mist before reaching the river below.
Los Roques Archipelago consists of approximately 350 islands and cays surrounding a single lagoon of 400 square kilometers. The national park designation came in 1972, making it one of the largest marine protected areas in the Caribbean Sea. The coral reef system hosts 280 fish species, 200 crustacean species, and 140 mollusk species according to surveys by Universidad Simón Bolívar. The islands are entirely coralline and limestone formations with no volcanic origin. Water visibility reaches 30 meters during calm seasons. The archipelago lies 160 kilometers north of the central coast.
Lake Maracaibo covers approximately 13,210 square kilometers, making it the largest lake in South America. The lake is technically a tidal bay connected to the Gulf of Venezuela by a 55-kilometer strait. Catatumbo lightning occurs where the Catatumbo River enters the lake at its southern end, producing an average 260 nights of electrical storms per year. NASA satellite data from 1997 to 2000 recorded up to 280 lightning flashes per hour during peak activity. The phenomenon results from methane and wind interactions in specific atmospheric conditions. Oil deposits beneath and around the lake made Venezuela the world's largest oil exporter by 1929.
The Llanos plains extend across approximately 300,000 square kilometers of central Venezuela into Colombia. During wet season from April to November, rivers overflow and flood vast sections, creating temporary wetlands. Dry season from December to March reduces water coverage by as much as 90 percent in some areas. The ecosystem supports an estimated 50 million capybaras, the world's largest rodent species reaching 65 kilograms. Spectacled caiman populations number in the millions across the wetlands. Cattle ranching has operated in the Llanos since the 1500s on hatos, large ranches that now number over 3,000.
Mérida operates a cable car system called Teleférico de Mérida that was the world's highest and longest when opened in 1960. The system ascends from 1,577 meters in the city to 4,765 meters at Pico Espejo in four sections spanning 12.5 kilometers. The cable car was closed in 2008 for reconstruction and reopened in 2016 with French-built Poma technology. The Venezuelan Andes reach their highest point at Pico Bolívar, 4,978 meters, which lost its glacier cap completely between 2009 and 2011 according to measurements by Instituto Nacional de Parques. The surrounding Sierra Nevada National Park was established in 1952.
Henri Pittier National Park, established in 1937, was Venezuela's first national park and initially named Rancho Grande. The park covers 1,078 square kilometers spanning from Caribbean coast to cloud forest at 2,400 meters elevation. The biological station at Rancho Grande has recorded 582 bird species, approximately 43 percent of all bird species found in Venezuela. The park contains the Portachuelo Pass at 1,130 meters, a migration route for raptors moving between North and South America. Annual raptor counts have recorded up to 3 million birds of prey passing through during October and November.
Orinoco River measures approximately 2,140 kilometers in length, making it the third longest river in South America after the Amazon and Paraná. The river discharges an average 30,000 cubic meters per second into the Atlantic Ocean. The Orinoco Delta covers approximately 41,000 square kilometers and remains largely uninhabited except for Warao communities living in stilt houses. The Casiquiare Canal is a natural waterway that connects the Orinoco basin to the Amazon basin through the Rio Negro, discovered by European explorers in 1744. Alexander von Humboldt traveled the Casiquiare in 1800 and provided the first scientific documentation of a river bifurcation connecting two major watersheds.
