Mariusa National Park

Mariusa National Park (Parque Nacional Mariusa, also called Delta del Orinoco National Park) protects about 331,000 hectares of tidal channels (caños), mangrove swamps and flooded forest in the Orinoco Delta, Delta Amacuro state, Venezuela. Established on 5 June 1991, it lies in the middle of the delta between Caño Macareo and Caño Mariusa, running out to the Atlantic, and forms part of the Delta del Orinoco Biosphere Reserve, which joined UNESCO's network in 2009. Mariusa is the Warao name for the area.

The park is the home of the Warao people, who live in stilt houses (palafitos) along the channels and travel by dugout canoe. There are no towns, roads or power grid inside the park; all movement is by boat.

The climate is hot and humid all year, with average temperatures of 25–33 °C. As of October 2026 the UK government advises against all but essential travel to this part of Venezuela, and against all travel to the area south of the Orinoco in Delta Amacuro state.

By Plane

No scheduled flights land in the delta. The nearest airports with domestic flights from Caracas are at Maturín and at Puerto Ordaz (Ciudad Guayana); from either, continue by road to the delta gateway town of Tucupita.

By Train

Limited Information available

By Car / Road

No roads enter the park. Roads end at Tucupita, the state capital, and at small river ports on the delta's edge. The roads are paved but may have potholes — drive carefully. Fuel availability can be unpredictable, so fill up in Maturín or Ciudad Guayana. Driving after dark is not recommended.

Bus: Long-distance buses and por puesto (shared car) services run to Tucupita from Maturín, Ciudad Guayana and Caracas. Fares are modest, usually USD 2–8 for regional routes.

By Boat

Boats are the only way into the park. Tour operators and lodges in and around Tucupita arrange river transfers and multi-day trips into the delta channels.

All transport inside the park is by water: outboard skiffs between lodges and Warao settlements, and dugout canoes (curiaras) for narrow channels where motors cannot go. Walking is limited to lodge walkways, village paths and guided treks in rubber boots. Arrange everything through your lodge or tour operator.

• Caño Mariusa and Caño Macareo — The main delta channels bounding the park, lined with mangroves.

• Wildlife — Delta birdlife, river dolphins, monkeys and caimans along the channels; early morning and late afternoon boat trips are best for sightings.

There are no restaurants inside the park; lodges and tour operators provide meals, typically river fish with rice, plantain and cassava bread (casabe). Tucupita has small restaurants and street food serving Venezuelan staples such as arepas, empanadas and cachapas.

Fresh fruit juices (jugos naturales) and papelón con limón (sugarcane syrup with lime) are common in Tucupita. Tap water and river water are not safe to drink. Bottled or purified water is essential; lodges supply it.

• Delta lodges: Stilt-built jungle lodges on the channels sell full-board packages including boat transfers and excursions.
• Tucupita: Basic guesthouses (posadas) and small hotels in the state capital for nights before or after a delta trip.

There are no shops inside the park. Warao communities sell moriche-fibre hammocks, baskets and carvings. Buy supplies, cash and water in Tucupita or before you reach the delta.
