Here at TourScoop, we love sharing our all-human, real-life advice about tour companies. In this article, I’m delving into Overseas Adventure Travel (O.A.T.), an active tour company with a solo specialty that’s owned by Grand Circle. I’m also including the company’s new-for-2025 tours.
Overseas Adventure Travel—casually referred to as O.A.T. (pronouncing each letter as opposed to naming the grain)—is a small-group tour specialist with tours on all continents.
As its name suggests, Overseas Adventure Travel tours tend to be fairly active, so participants should be comfortable with six to eight hours of activity each day, including walking distances ranging from three to six miles.
O.A.T. stands out with its solo guest focus (more on that below), and includes a generous number of no-additional-cost single spots on its tours. It also has women-exclusive departures on many itineraries.

Overseas Adventure Travel itineraries tend to favor accommodations that favor authentic experiences over amenities. Another thing that sets O.A.T. apart is that airfare is often bundled into the up-front price of the tour (unless you specify that you want to book your own travel). O.A.T. is one of the family of Grand Circle Corp. companies, also including Grand Circle Travel and Grand Circle Cruise Line.

Tour types
Overseas Adventure Travel gives all its tours an Activity Level Rating that ranks tours from one (easy) to five (strenuous) to help travelers find the right fit. It has both women-only departures and many no-additional-cost single traveler spots on tours.
There are multi-country and single country tours. On many tours, O.A.T. creates spaces for discussion and learning with its Controversial Topics program that covers topics such as Scottish independence on its Scotland Revealed itinerary and female genital mutilation on its Safari Serengeti: Tanzania Lodge & Tented Safari tour.
Tour guides
Overseas Adventure Travel’s tour guides are called Trip Experience Leaders. All are fluent in English and have a range of skills, certifications, and experience specific to the tour destination and experience. Trip Experience Leaders focus on both the logistical and the experiential, and help connect travelers with destinations by sharing firsthand insight that brings a destination to life.
Inclusions/extras
Inclusions are tour-specific (there’s a “What’s Included” section on each tour’s page), but generally include round-trip flights, many (but not all) meals, transportation, accommodations, activities, and gratuities for local guides, porters, etc. As with most tour companies, gratuities for trip experience leaders is separate.
Typical travelers
O.A.T.’s guests are mostly American travelers aged 50 and older. In the last few years, Overseas Adventure Travel has seen a major jump in the number of solo travelers—more than half of all O.A.T. guests are now solo travelers, and 80% of these solo travelers are women.

And a number of itineraries also have women-exclusive departures.

After booking, travelers have access to all trip details through the “My Planner” section on the website. The section includes details like flight information, destination weather, and itinerary information.
Then, two weeks before departure, travelers receive all their final documents, and are also contacted by their Trip Experience Leader. Any additional questions can be directed to the customer service email or phone number.
