Did you know? Our Rainforest Expeditions guests find the relatives of these shy, eight-legged creatures on night hikes!


The Brazilian Wandering Spider is the name of many spider species in the Phoneutria genus. They are large, intimidating, and infamous for being the most toxic spider venom in the world. These spiders actually occur in many areas outside of Brazil, from Costa Rica to Argentina. Nevertheless, the Brazilian Wandering Spider (Phoneutria nigriventer) is the best-known member of this group of eight species. This is because it lives near humans and occasionally bites people. It is a familiar spider in many parts of Brazil. It actively searches for prey instead of waiting at a spider web. That is where it gets its name: Brazilian Wandering Spider.

The Brazilian Wandering Spider doesn’t actually occur in the Tambopata rainforest. However,  there are at least two other closely related species that live in the Peruvian jungle around the Rainforest Expeditions lodges. Despite the hype that the Brazilian Wandering Spider receives from the press, this creature rarely bites people. The species in the Tambopata rainforest do their best to stay hidden at all times. The wandering spiders of Tambopata are food for large birds and peccaries. Thus, they would much rather hide in the leaf litter than rush out and bite someone.

Guests of Posada Amazonas, Refugio Amazonas, and the Tambopata Research Center usually encounter wandering spiders on night hikes in the rainforest. Getting bit by one is extremely unlikely unless you try to pick the spider up or stick your hands into leaf litter, bromeliads, or under fallen logs.

Brazilian Wandering Spider Fun Facts



  • Most toxic spider venom is known: The venom of at least one species of Phoneutria is much more toxic than the Black Widow Spider and can easily kill mice with one bite. Human fatalities in Brazil are an extremely rare occurrence.

  • No web: Unlike many other spiders, the wandering spiders don’t build webs but actively search for their prey.

  • The banana spider: Wandering spiders occasionally turn up in shipments of bananas! One such stowaway actually bit a man in England in 2005. He survived but spent a week in the hospital!

  • Understory predator: These spiders are active, aggressive predators that feed on large insects, small lizards, mice, and frogs.


How to plan your Amazon jungle travel to see Brazilian Wandering Spiders and other jungle wildlife



  • Go on a night hike: These large spiders are most active at night. We have nightly hikes in the rainforest with trained guides so you can see wandering spiders and other nocturnal jungle animals.

  • Make science happen with AmazonCam: even if Amazon Travel is not in your short-term plans, you can connect with Amazon wildlife!

  • And of course, if you´re thinking (or even dreaming) of Amazon jungle Travel, drop by to chat with the Amazon Travel experts. We will help you get there.

We had an excellent 5 night stay at TRC with two couples. The remote Lodge and accommodation are unique especially with the open walls to the jungle in the rooms. The guides were first rate with superb knowledge and their ability to spot fauna in the dense jungle was incredible. We saw many species of monkeys; macaws, parrots, tapirs, etc.. even lucky enough to spot a jaguar. Food and service was really good. While not cheap it was I think very good value for money. We really enjoyed all the hikes and citizen science activities as well, he trips on the river and the clay licks. Overall amazing experience! As it’s the jungle not a zoo, you can’t guarantee that you’ll see everything all the time so allow enough days to properly explore. Read all

A once-in-a-lifetime experience in the middle of the rainforest. From airport pickup in Puerto Maldonado to the lodge and back, everything was exceptionally well organised. Communication was clear throughout, with the team always explaining what would happen, where to be and what to take care of. The staff at both HQ and the lodge were incredibly attentive, making the entire stay feel completely carefree. At this price point, this is the level of service you expect, but it is still impressive to experience it in such a remote setting. The food was another highlight: very well curated and balanced, with plenty of options at every buffet and, surprisingly, we never had the same dish twice. Read all

This was an excellent experience!! Highly recommend if you’re interested in visiting the Amazon Rainforest and Tambopata region. Especially happy with our guide Miguel, who was highly professional, informative, and organized. It was an immersive adventure and we got to see so many unique plants and animals. 10/10! Read all

Amazing experience at Refugio Amazonas. Rooms were comfortable and clean. Great buffet spread every day. Staff were friendly and attentive. Our guide Alan was very informative. Overall would definitely recommend a visit! Read all

We stayed 3 nights at Posada Amazonas during our summer trip to Peru, and it was definitely one of the biggest highlights of the whole journey. The staff were incredibly warm and welcoming. Our guide, Joss, was professional, friendly and amazingly knowledgeable. Sometimes it honestly felt like he could communicate with the animals — he could spot black caimans or giant river otters from hundreds of metres away! The excursions were unforgettable. We saw beautiful macaws, giant river otters, capybaras, sloths, tarantulas, an anaconda, different species of monkeys, toucans and so much more. I especially loved the rainforest walks and joined both the daytime and night walks. Every walk felt completely different, and you never knew what you might find. What also made the stay special was the lodge’s involvement in scientific and environmental projects. There was a talk every evening, and we learned a lot about the rainforest and its wildlife. We also joined the “Discover New Species” activity and helped search for possible new species of tiger moths — such a fun and memorable experience. The lodge itself is definitely rustic luxury rather than a city-style 5-star hotel. There is no air conditioning or hair dryer, but the hot shower, fan and hammock in the room were all very comfortable and suited the rainforest setting perfectly. And surprisingly, the internet connection was excellent — even the boats had Starlink! One of the things I appreciated most is that Posada Amazonas is a collaboration between Rainforest Expeditions and the local Indigenous community that owns the land. Many community members are directly involved in running the lodge, and you can really feel how much the staff care about and are connected to this rainforest, which is part of their ancestral home. If you are looking for an authentic, educational and truly memorable Amazon rainforest experience, I highly recommend Posada Amazonas. We absolutely loved our stay. Read all

The Tambopata Research Center (TRC) offers a well-organized immersive rainforest experience within the Tambopata National Reserve. The TRC and its accommodations put a spin on the term creature comforts by keeping guests comfortable while they commune among the creatures within the rainforest. I appreciated, through what I observed and the interactions I had, the attentiveness of the TRC team members. They knew their guests and seamlessly organized a lot for our benefit. The center assigns guests to a small group with a dedicated guide. In my case, Erick Arguedas was a superb ambassador for all things living in the rainforest, in part because it was the environment in which he grew up. His role was to ensure we got the most out of our visit. Being a long-term TRC guide gave him the expertise he needed to easily fulfill this role. Read all

Our stay at Refugio Amazonas was a great experience from beginning to end. The entire trip was very well organized, and having a tour guide with you throughout the experience made everything easy and enjoyable. Our guides, Dennis and Tuto, were excellent. They both spoke English very well and did a fantastic job explaining the different birds, trees, plants, and animals we encountered. Their knowledge really made the excursions much more interesting and helped us appreciate the Amazon on a deeper level. The expeditions were definitely a highlight. I highly recommend the clay lick, sunset cruise, observation tower, river boat tour, and night walk. Each activity offered something different, and we were able to see so much wildlife. The food was also excellent. Everything was fresh and tasted great. I especially enjoyed the protein dishes, fresh fruit, and yuca potatoes. Considering how remote the lodge is, we were very impressed with the quality of the food. The rooms are very open to nature, which is part of what makes the experience so unique. We saw monkeys right from our room, along with many birds and lizards. We even had a frog visit our room at night—which was definitely an interesting Amazon experience! 😂 One thing to be aware of is that the walls between rooms are quite thin, so you can hear your neighbors at times. Overall, the entire experience was absolutely worth the trip. If you’re visiting the Peruvian Amazon, I would strongly recommend Refugio Amazonas. The wildlife, guides, excursions, food, and being completely immersed in nature made this one of the highlights of our Peru trip. 🌿🦜🐒 Read all

Our stay here was one of the favorite parts of our trip to Peru. One of the most memorable parts of the stay is how wonderful the guides were. We had two different guides during our stay: Jos and Jorge. Jos had an amazing connection with the birds, knowing all the bird sounds by ear, he could imitate most of them. His passion for the birds was evident when we went out to see them, and during a visit to look for macaws at the clay lick, he moved locations just so we would have the opportunity to see them. When we viewed them up close through a new blind that had been built, his joy was as much as ours, delighting as if it was his first sighting. Jorge had a beautiful spirit that he shared with us during our time with him. Growing up in the community there, he had so much knowledge about the plants and trees. He introduced us to a medicinal plant, and had stories about some of the different trees. We felt well cared for by both guides. We also enjoyed the nightly science talks, teaching us about some of the ongoing projects which helped us feel more connected to the area. The food was wonderful, and all the staff were extremely helpful throughout our stay. Read all

Amazing location and truly deep jungle. This organisation has three lodges and this is the nearest to Puerto Maldonado but don’t think that the wildlife here is any less than the lodges further along the river. We saw a LOT of different animals, birds and variety of colours. Well worth the stay. Read all

We stayed last february for 4 nights in the TRC lodge. I never could have imagined that I would explore the amazon in such confortable and immersive way. The lodge itself is such a luxurious place, in the middle of nowhere! The food was nicely curated everyday to offer new bits and pieces of the Peruvian cuisine. The absolute highlight of our stay here was for sure the activities and our guide Carmen, who accompanied us everyday! We were able to choose our everydays activities with our very reduced group and our guide. Carmen guided us on very activity, spotting and explaining what animals we saw and interesting facts about our surroundings. Her knowledge and excitement were so infectious that it would even make the sightings even more special! Read all

One of the most unique experiences we’ve had! You are deep in the heart of the Amazon and truly feel immersed in nature. Our guide Dino was awesome and taught us so much about the rainforest-he is like a walking encyclopedia, and his love for the forest really shows. Also very unique to listen to nightly talks from the research team-it really adds to the experience. Food was great and staff very friendly. Bring lots of bug spray and an adventurous spirit!

The lodge was fantastic; they were very attentive to our needs. The dining staff brought special bread for my wife because of her celiac disease and offered to prepare dishes specifically for her to meet her dietary needs. The lodge guides were truly knowledgeable and went out of their way to help us see all the local wildlife. I especially loved the mosquito net service they provided. I was worried we’d be eaten alive, but their setup is fabulous; I had no concerns once I saw how they installed the impenetrable nets and curtains. The meals were as good as—or better than—anywhere else we ate in Peru. We saw the following animals: macaws, parrots, parakeets, pale-winged trumpeters, tamarins, caimans, capybaras, and a ton of insects on our night hike. Read all
