Sandoval Lake: Discover the Tambopata Reserve in the Peruvian Amazon

Immerse yourself in the Amazonian biodiversity at Sandoval Lake, one of the most popular destinations in the Tambopata National Reserve in Madre de Dios, Peru. This destination attracts thousands of visitors every year. Our specialized travel agency takes you to discover this Amazonian paradise in a comfortable, safe, and exciting way.

Where is Sandoval Lake located?

Sandoval Lake is located in the Peruvian Amazon, within the Tambopata National Reserve (Madre de Dios). It is situated on the banks of the Madre de Dios River, east of the city of Puerto Maldonado. The lake measures approximately 125–127 hectares and is an ancient oxbow lake formed from a former meander of the Madre de Dios River. It is one of the most visited corners of Tambopata due to its easy access and impressive wildlife.

How was Sandoval Lake formed?

The geological formation of Sandoval Lake occurred when a tributary of the Amazon River changed its course, leaving behind an isolated section that is now this lake. Sandoval Lake is an ancient oxbow lake with clear waters that became a unique habitat for local wildlife. Due to its fluvial origin, the waters are rich in fish (such as the introduced arapaima) and surrounded by aguaje palm swamps, wetland areas filled with moriche palms that give the lake its characteristic beauty.

Location and access from Puerto Maldonado

The lake is only 30 minutes by boat from Puerto Maldonado (after navigating the Madre de Dios River). From there, you must walk approximately 3 km along a trail to reach the lake shore. During the river journey, you already begin to feel the surrounding jungle. The official site of the Tambopata Reserve indicates that the Sandoval sector is accessible through a half-hour river ride followed by a moderate hike. The entire route is signposted, and along the way you will find an Interpretation Center and an observation tower offering panoramic views of the lake.

How to get to Sandoval Lake?

To visit Sandoval Lake, you must first arrive in Puerto Maldonado. If you are coming from Cusco, the overland journey takes about 10 hours (465 km). From Lima, it is common to take a 1 hour and 20 minute flight. Once in Puerto Maldonado, entrance to the protected area requires hiring a tour with tourism operators authorized by SERNANP. Your journey continues by boat along the Madre de Dios River to the Sandoval Reserve port.

• From Puerto Maldonado: You board a boat and navigate downstream for about 30 minutes toward the lake access point.
• Entrance to the Reserve: Access is only permitted with authorized guides (see official list). Tours include permits and entrance fees.
• Arrival at the Lake: After the 3 km walk, you will arrive at Sandoval Lake. Along the trail you will see the Interpretation Center and, at the end, an observation tower to admire the lake.

Tips for Visiting Sandoval Lake

• Weather and season: May–October is the dry season; bring lightweight clothing and insect repellent. In November–April (rainy season), bring a lightweight rain jacket.
• Luggage: Small backpack with water, snacks, camera, and binoculars. If your tour departs from Cusco, leave heavy luggage in storage.
• Safety and health: Recommended vaccinations (yellow fever, tetanus). Do not forget boots or closed-toe shoes.
• Environmental respect: Do not feed animals or collect plants. Follow the guide’s instructions on the trails.
• Children and seniors: There is an accessible trail for children and older adults. Bring a hat and sunscreen.

Best Time to Visit Sandoval Lake

• Dry season (May–October): These are the ideal months. The weather is drier and the trails are easier to walk, making hikes to the lake more accessible. Mornings are cool and afternoons are hot. There are fewer mosquitoes than during the rainy season, and cameras work better without so much humidity.
• Rainy season (November–April): Although it rains daily, the forests look greener and the rivers rise. During the rains, river dolphins travel farther upstream, but hiking can become difficult. If you travel during this period, be prepared for short but intense rainfall. Many people prefer to avoid this season because of logistics, but it is also the time when the jungle flourishes most.

In general, we recommend planning your trip to Sandoval Lake between May and October to avoid heavy rains. However, even during the rainy season, tours operate normally (with ponchos and flexible schedules).
