Cueva de los Tayos | Merida

Cueva de los Tayos is a cave system located in the Guiana Highlands region of Venezuela, near the border with Brazil.

Visual Characteristics

The cave entrance is a fissure in a limestone cliff face, approximately 10 meters wide and 5 meters high. The interior consists of karst formations, including stalactites and stalagmites, with passages varying in width from 1 meter to over 20 meters. The rock is primarily limestone, with some areas exhibiting mineral deposits that create varied coloration.

Location & Access Logistics

The cave is situated approximately 150 kilometers south of Mérida. Access requires a 4-hour drive on the Carretera Transandina (Route 7) towards El Vigía, followed by a 2-hour drive on unpaved roads (requiring a 4x4 vehicle) towards the community of San Isidro. From San Isidro, a 3-kilometer hike is necessary to reach the cave entrance. There is no designated parking; vehicles are typically left at the trailhead near San Isidro. Public transport is not available to the cave site.

Historical & Ecological Origin

Cueva de los Tayos is a natural karst cave formed by the dissolution of limestone over geological time. Its ecological significance lies in its role as a habitat for various cave-dwelling species, including bats and insects. The name "Tayos" refers to the oilbirds (Steatornis caripensis) that inhabit the cave.

Key Highlights & Activities

Exploration of the cave's main chambers is possible. Observation of oilbird nesting sites is a primary activity. Guided tours are available, focusing on geological features and the cave's ecosystem. Photography is permitted within designated areas.

Infrastructure & Amenities

There are no facilities within the cave or at the immediate entrance. Basic amenities such as restrooms or food vendors are not present. Cell phone signal is unreliable within the cave and limited in the surrounding remote areas.

Best Time to Visit

The dry season, from December to April, is recommended for easier access due to less rainfall impacting the unpaved roads. The best time of day for observing oilbirds is typically at dusk when they emerge to forage. The cave temperature remains constant year-round.

Facts & Legends

The cave is named after the Tayos, or oilbirds, which are nocturnal birds that nest in large colonies within the cave. Their guano forms a significant part of the cave's ecosystem. Local folklore suggests the cave extends deep into the earth, connecting to other subterranean networks.
