About MT Amazon Expeditions

We were founded in 1983, and have been offering Peruvian Amazon expeditions ever since. The company official name is Margarita Tours, Inc.*, after Margaret, the original owner, but when it was turned over to a long-term employee on 7 Sept 1994, we elected to revise the name we commonly use. Too many prospective clients had visions of non-stop alcoholic drinks in wide glasses with a slice of lime and salt on the rim.... While we might enjoy a Margarita from time to time ourselves, it isn't what we're all about!

What are we proud of? 

  • Our permanent commitment to the Amazon - both to the environment and to the people.
  • Our unflagging support of Project Amazonas, a non-profit organization that was born out of Margarita Tours in 1994. 
  • Our clients. These are people who want to really experience the Amazon ("bugs", humidity and all), and who keep coming back!  From 20-30% of the participants on any given expedition are repeat clients. Many also become regular donors to Project Amazonas. 
  • Our staff. Our Peruvian staff are top-notch, and work very hard to make very Amazon experience memorable in all the right ways. 

What are we passionate about? 

  • Getting out into the field! MT Amazon's owners, trip leaders and Peruvian staff all love getting off the beaten track in the Amazon. 
  • Finding new cool things - each and every expedition - we're constantly learning!
  • Providing young people and students of all ages a horizon-broadening life experience. 
  • Mark Twain. Huh? Sure! Who else had the wit to note “I have found out that there ain’t no surer way to find out whether you like people or hate them than to travel with them.” (Tom Sawyer Abroad - 1894). Engaged or soon-to-be engaged couples take note - we will offer you a discounted rate!

Our clients come from all walks of life and have ranged from 8 to 80 years of age. Repeat clients always receive a discounted expedition rate, and the 10th expedition is completely complementary. Stop snickering - we've made good for a 10th expedition! About 60% of our clients are from the USA, 10% from Canada, 20% from Europe, and 10% from scattered locations around the globe.

Michael Barber (Tropical Fish Expert)

Michael has been a fish enthusiast and keeper for more than fifty years. His journey started with his parents’ gift of a five-gallon stainless steel and slate aquarium with box filter and stainless incandescent hood. As he grew and endured spun fiberglass embedded in his fingers and unexpected electrical groundings, he graduated from live bearers to breeding Pearl Gouramis before the age of ten and Discus before twelve.

His passions are Calichthydae, Apistogrammas and Apistogrammoides pucallpaensis. He has had nearly fifty species of Corydoras, Brochis and Aspidoras in his “Testanzonia”, a large room dedicated to fish, in which at any time he maintains sixty to one hundred tanks. He has bred over fifty species of Calichthydae, dozens of Apistogramma species and many, many more.  He is an expert in the biology and chemistry of breeding cycles, and regimens for the transport and quarantine of imported Amazon fish. 

He ventures to the Amazon basin frequently to collect fish and thoroughly enjoys being a mentor introducing others to their first Amazon expedition with co-leader, Devon Graham. In 2014, he began facilitating shipping fish caught on these trips. In 2015, in partnership with Ian Fuller, they established a new fish collecting venture, GoWildPeru, in Puerto Maldonado, Madre de Dios, Perú.

Michael is an active member of many fish organisations including: Potomac Valley Aquarium Society (PVAS – current treasurer and past president), Greater Washington Aquatic Plant Association (GWAPA), the Capital Cichlid Association (CCA), James River Aquarium Society (JRAS) and the Catfish Study Group. He is past Co-Chair of the All-Aquarium Catfish Convention. Another membership of note is The American Begonia Society, Potomac Branch.

Michael is available to present to fish clubs about collecting trips with MT Amazon Expeditions. You can contact Michael here.
