We invite you to join the 2021 SAVE THE FROGS! Costa Rica Osa Ecotour! The tour takes place June 5th to 12th, 2021.

This research focused adventure will take us to the amazingly biodiverse Osa Peninsula in southwest Costa Rica, where we will enjoy the beaches and rainforests and have an abundance of opportunities to find and photograph amphibians.


Costa Rica’s Osa Peninsula is a remote corner of the country far from the more famous tourist-filled destinations. It has well-protected rainforests, serene beaches, poison dart frogs, sea turtles, tapirs, fabulous waterfalls and an incredible biological research station. There are lots of frogs to be found, making the Osa Peninsula a perfect place for a SAVE THE FROGS! Ecotour.


Please complete the expression of interest form if you would like to join the tour.

Dart Frog Tadpoles

A Lot More Than Just Frogs

The ecotour has a frog focus, but is much more than just frogs! We will see and learn about a variety of wildlife, including sea turtles, snakes and monkeys. We will even be joined by a professional bird guide for the entire tour, so if you love waking up at the break of dawn to spot colorful birds, bring your binoculars and expect to see a lot of amazing birds!


While our nights will be filled with frogs, daytime offers a range of activities, including hiking to waterfalls; swimming at beaches and learning about the range of scientific activities taking place in the Osa Peninsula.


We will meet many biologists and local wildlife guides who will educate us about tropical ecology, wildlife, ecotourism, and the threats and opportunities facing Costa Rica in the modern era.

In short, even if you are not a frog fanatic (yet!), as long as you love nature and wildlife, you will have an incredible time on this ecotour.

We hope to see you in Costa Rica!

This Tour Is For Adults - We Have A Separate Tour For Families

In the past we have led tours that had a mix of ages from kids through retirees. This year we are leading multiple tours to Costa Rica:

  • This Osa tour, which is adults only and requires a sufficient level of fitness and physical exertion for daytime hikes in hot humid tropical weather.
  • The SAVE THE FROGS! Costa Rica Ecotour For Families, a family-friendly and family-focused ecotour designed to be fun, safe and interesting for travelers of all ages. Kids, parents and grandparents are all welcome on that tour.

Meet Your Amphibian Guide

Marina Garrido

The 2021 SAVE THE FROGS! Costa Rica Osa Ecotour will undoubtedly be an amazing experience because we have amphibian expert Marina Garrido joining us! Marina is a biologist who conducts research at Osa Conservation, where she has worked full-time for almost three years. Living in the middle of the rainforest she couldn’t help but fall in love with amphibians. She is currently creating the first ever Conservation Action Plan for Phyllobates vittatus, an endangered species endemic to southwest Costa Rica. Recently, she joined the Department of Wetland Ecology of Doñana Biological Reserve, studying amphibians’ plasticity. She cannot wait to go back to the rainforest to see her hopping poisonous friends!
