Aripo Cave (Aripo Main Cave) is a cave in Trinidad and Tobago's Northern Range. With a length of 862 meters and a depth of 160 meters, this cave is the longest accessible cave in Trinidad & Tobago and among Most Impressive Caves in Trinidad and Tobago. It's one of a number of caverns formed by recrystallized limestone. The cave is a well-known bat roost, and bats produce significant volumes of guano, which supports a large number of cave-dwelling invertebrates.

The Oilbirds are one of the Aripo Cave's most known residents. These are the world's only night fruit-eating birds. They graze at night, using echolocation to navigate in the same way that bats do. The Aripo Forest is vividly ornamented with the fiery orange blossoms of the mountain immortelles during the month of February ( Erythrina poeppigiana ). The immortelle trees were initially planted to offer shade for the cocoa, and it is thought that when they bloom, it marks the beginning of the dry season.

Crusoe Cave, one of the Most Impressive Caves in Trinidad and Tobago, is a marine cave on the island of Tobago in Trinidad and Tobago, located near Crown Point. The cave is called after the titular protagonist of English writer Daniel Defoe's 1719 novel Robinson Crusoe. Crusoe is stranded on an unknown island mentioned as being within sight of Trinidad in the novel; others believe Crusoe's island was modeled after Tobago. This name has been used to refer to the cave since 1890.

Cumaca Cave is a major cave system in Trinidad's northwestern region, which is part of the Northern Region. Oropouche is another name for this cave. Bats and oilbirds can be found in the caves ( Steatornis caripensis ). These are the world's only night fruit-eating birds. They search for the night by echoing in the same way as bats do, but with a higher click that people use. In the cave, there are also hypogenic fish.

The conjugal catfish, Rhamdia quelen, often known as the South American catfish, was once thought to be a different cave species and was given the name Caecorhamdia urichi. However, it is currently known as the troglobite variant of Rhamdia QUELEN, because it has a lower eye size and a reduced pigmentation.

The Tamana Caves (or Tamana Cave) are a cave system in Eastern Trinidad that is located on the northern slope of Mount Tamana. Mount Tamana is a 307-meter-high flat extension of the Guaracara limestone and Tamana Formation in the eastern Central Range's Miocene epoch. The main cave, according to Julian Kenny, is divided into 18 sections. Two chimneys and a walk-in chamber were documented by him.

The walking chamber was linked to the bat chamber, which was heavily frequented by bats, as well as a crawl hole that led to the remainder of the cave system. There was an underground stream and a tunnel leading to the chimney region behind the crawl hole. The passages continued to fall after that, ending with what Kenny referred to as the "new deep" and "long deep," places that had not been investigated before he was released.
