Overseas Adventure Travel (OAT), the Boston-based tour operator specializing in small-group experiences for travelers aged 50 and older, has expanded its portfolio with two new itineraries spanning Southeast Asia and South America. The programs, available for 2026 and 2027 departures, blend land exploration with privately chartered small-ship cruising—a format the company has refined over decades.
Mekong River: Vietnam to Cambodia in 15 Days
The new Mekong River itinerary takes guests aboard the RV Indochine II, a 62-passenger vessel, for a 15-day journey from southern Vietnam into Cambodia. Highlights include the floating markets of Cai Be, the royal palace and temples of Phnom Penh, and the UNESCO World Heritage site of Angkor Wat. The trip is priced from $6,695 per person, including round-trip airfare from the U.S., and features a low-cost single supplement—a key selling point for solo travelers in this demographic.
OAT caps group sizes at 16 to 25 travelers, ensuring personalized attention and access to less-visited destinations along the Mekong Delta. The itinerary is designed to provide intimate cultural immersion, with local guides leading excursions to villages, markets, and historical sites.
Chilean Fjords: Santiago to Patagonia in 13 Days
In South America, OAT introduces a 13-day adventure combining the cultural vibrancy of Santiago with the natural grandeur of Patagonia. Travelers will hike in Torres del Paine National Park and embark on a five-night cruise through the Chilean fjords aboard the MV Skorpios III. The cruise portion navigates the intricate waterways of Patagonia, offering views of glaciers, waterfalls, and wildlife such as penguins and sea lions.
Priced from $8,499 per person including airfare, this itinerary also offers a low-cost single supplement. The land component includes guided tours of Santiago’s historic neighborhoods and wine valleys, while the ship serves as a mobile base for exploring remote fjords that larger vessels cannot access.
OAT’s approach mirrors the growing trend of small-ship cruising favored by operators like Azamara, which emphasizes destination immersion over onboard scale. The company’s decision to pair land programs with chartered vessels allows it to control the guest experience end-to-end, a model that appeals to seasoned travelers seeking authenticity without the crowds.
Expansion Across Four Continents
These two itineraries are part of OAT’s broader expansion strategy, which now spans four continents. The company has long focused on off-the-beaten-path destinations, and the new offerings reinforce its commitment to combining cultural depth with active exploration. Bookings are open now, with departures scheduled through 2027.
For travel advisors, OAT’s low-cost single supplement is a notable differentiator in the 50-plus market, where solo travelers often face steep premiums. The all-inclusive pricing—covering airfare, accommodations, most meals, and guided excursions—simplifies the booking process for agents and clients alike.
As the adventure travel sector continues to rebound post-pandemic, OAT’s investment in new itineraries signals confidence in demand for small-group, multi-modal experiences. The company’s focus on mature travelers aligns with demographic trends: the 50-plus age group holds significant disposable income and travel intent, particularly for trips that combine comfort with discovery.
Travel professionals can access detailed itineraries and commission structures through OAT’s trade portal. The company also offers group booking incentives for agents who organize multiple travelers on the same departure.
