Guide to Pacaya Samiria: Peru’s Explosive Jungle of Mirrors

Pacaya Samiria is one of Peru’s most extraordinary natural treasures, a vast protected area that showcases the raw beauty and biodiversity of the Amazon Basin. Located in the Loreto region of northeastern Peru, the park is often referred to as the “Jungle of Mirrors.” The name is derived from its flooded forests and calm waterways that reflect the sky and surrounding greenery.

The park lies between the Marañón and Ucayali rivers, two major tributaries that later join to form the Amazon River. Its landscape is dominated by seasonally flooded forests, oxbow lakes, rivers, and wetlands, which change dramatically between the dry and rainy seasons.

During the high-water months, large areas of forest are submerged, allowing visitors to travel deep into the jungle by boat. In the drier months, exposed riverbanks and trails make it possible to explore on foot, revealing a different side of the ecosystem. Here’s our comprehensive guide to Pacaya Samiria National Park;

Overview of Pacaya Samiria National Park

Spanning an impressive 8,042 square miles, Pacaya Samiria National Park is one of Peru’s largest protected natural areas. It encompasses parts of the Loreto, Requena, Alto Amazonas, and Ucayali provinces. Established in 1982, the park takes its name from the Pacaya and Samiria rivers that traverse its vast territory. A defining feature of the park is its seasonal cycle of rising and falling rivers.

During the rainy season, extensive flooding transforms much of the forest into waterways, reaching a peak known as the crescent in May. As the rains subside, water levels gradually drop until their lowest point in August. Left behind are a network of smaller bodies of water that sustain a rich array of aquatic life.

The park’s humid, tropical, and flooded forests create a self-contained ecosystem, dotted with oxbow lakes such as Lake El Dorado, where fish and other wildlife thrive. The dry season concentrates fish into smaller areas, creating fertile feeding grounds for the park’s diverse bird population.

Humans also benefit from this seasonal rhythm, as the estimated 42,000 residents of the park rely on its resources for sustenance. During the dry months, exposed riverbanks and beaches allow locals to cultivate crops such as rice and beans. The same sandy areas serve as nesting grounds for the park’s two large species of river turtles.

Best Time to Visit Pacaya Samiria National Park

Pacaya Samiria National Park offers two very distinct seasonal landscapes shaped by the Amazon’s rhythm of water. Between October and April, the region experiences heavy rainfall, with water levels in rivers and creeks rising dramatically. During this high-water season, the park earns its nickname, the ‘Jungle of Mirrors,’ as the calm black waters reflect the sky and surrounding forest, creating stunning visuals.

Motorboat travel becomes the most obvious option, allowing visitors to navigate deep into the flooded forests. Wildlife adapts to these conditions by taking refuge in elevated areas that remain dry, making sightings less concentrated but still possible.

From May to September, the low-water season transforms the park. As the rains subside, water levels gradually retreat, reaching their lowest in August. This exposes dry patches that make trekking feasible, while remaining creeks and lakes concentrate fish and other wildlife. Large sandy beaches also emerge, providing crucial nesting grounds for species such as the charapa and taricaya turtles.

Getting to Pacaya Samiria National Park

Accessing Pacaya Samiria National Park requires joining a guided tour, as independent travel into the reserve is not permitted. Most tours depart from either Iquitos or from the nearby town of Nauta, which is a few hours’ drive away. For travelers starting in Lima, the journey begins with a flight to Iquitos, typically lasting around one and a half to two hours.

Upon arrival in Iquitos, the tour operator will arrange overland transport, often a taxi or pre-booked transfer, to reach Nauta. The port town is located about two hours away along a paved road. From Nauta, the adventure continues by boat, navigating the rivers that thread through the reserve, such as the Marañón.

Depending on the chosen destination, like the Yanayacu Pucate Basin or the more remote Pacaya Basin, this river journey can take anywhere from 3 hours to a full day. Guided tours generally handle all stages of the trip. Some provide meals, entrance fees, and other small incentives like bottled water.
