Costa Rica: Natural Parks & Tropical Forests

Overseas Adventure Travel offers unique small group adventures worldwide to Americans over 50. By land and sea, we explore on—and off—the beaten path with a resident OAT Trip Leader, immersing ourselves in local cultures, sampling unique modes of transportation, and staying in authentic lodgings that reflect the essence of your destination. Grand Circle Small Ship Cruises serves both our GCT and OAT brands with an award-winning fleet known for exceptional value and high-quality experiences in Europe, Asia, Africa, and South America. Custom-designed according to our travelers’ specifications, our fleet includes 50+ small river and ocean-going ships that we own or privately charter.

Grand Circle Corporation is a global enterprise—comprised of a family of travel companies—committed to changing people’s lives by offering high-impact experiences to our travelers and building local communities through philanthropy, social entrepreneurship, and volunteerism.

Simply by traveling with OAT, you support the work of the nonprofit Grand Circle Foundation, which was created with the mission of changing people’s lives through travel—both those of our travelers, and of the people who welcome us so warmly into their homelands.

Journey with the Leader in Adventure Travel and Watch Your Dreams Take Flight: It is the stuff of dreams: gazelles bowing to lap at a glassy pool in the Serengeti as the vast sky turns purple with night, the tiered splendor of the Himalayas, rising behind a Tibetan monastery. Dreams like these are everyday realities for OAT travelers, thanks to the principles which ground every OAT adventure: value, choice, discovery, and carefully paced itineraries.

Our Value puts your travel dreams within reach: OAT can help you realize your travel dreams for a lot less than you thought possible. Together with our regional offices located throughout the world, we’ve been able to establish long-term relationships with many local vendors and hotels. Buying direct brings down our costs—and allows us to pass the savings on to you. And negotiating directly for hotel space also allows us to secure as many single room allotments as possible for our solo travelers. That way, we can also extend our great value to solo travelers. In fact, we offer the best value for solo travelers, guaranteed.

The Choice is yours: You’ll always have plenty of choices with OAT. We offer you a breadth of awe-inspiring travel destinations—from the peaks of the Andes to the sweeping desert sands of the Sahara to the rugged natural beauty of Iceland. You'll also enjoy more trip extension choices than ever before—like hiking to ancient monasteries in Bhutan or discovering the Moai monolithic rock statues on Easter Island. You have plenty of choices within each adventure, too, including several interesting optional tours. And the free time we’ve woven into our itineraries allows you plenty of opportunities for independent exploration. You can shop, unwind, perhaps linger at a sidewalk café, visit an interesting gallery or museum, or explore a cobbled street that caught your eye earlier in the day. You can do as much or as little as you want on an OAT adventure—the choice is yours.
