The adventure
Pack your bags — this is Southeast Asia, done your way. Over Thailand, Cambodia, Vietnam, and Laos you’ll hike with Thailand’s hill tribes, watch the sun rise over Angkor Wat, and dive headfirst into Siem Reap’s buzzing nightlife. Cruise through vibrant cities, taste street food that hits harder than takeout, and hop night markets where adventure feels endless. Between the big moments, there’s plenty of free time to chase your own vibe — whether that’s temple-hopping, café-hopping, or bar-hopping. By the end, you’ll leave knowing you didn’t just visit Southeast Asia, you lived it.
Arrive at any time and welcome to Siem Reap, Cambodia!
Tonight, meet your CEO and get to know fellow travellers as you cheers to new adventures.
Watch the sun rise over the majestic and mystifying ruins of Angkor Wat. Then, taste all manners of salty, sweet, spicy, and sour with a delicious Khmer meal at a restaurant kickstarted by our non-profit partner, Planeterra, or with a local family. Later, head to the infamous Pub Street, where the party goes round the clock. Grab a bite to eat (deep-fried tarantula, anyone?) and let the beats move you through market stalls and bars.
Travel to Phnom Penh, Cambodia’s busy capital nestled along the mighty Mekong River. Get your bearings on an orientation walk and spend the rest of the evening at leisure.
Spend the day diving deep into Phnom Penh's culture and history. Opt to reflect on one of Cambodia’s darkest periods with a visit to the Tuol Sleng Prison and the Killing Fields. Or venture to the Silver Pagoda or Royal Palace for a more peaceful experience. Later, discover the foodie side of this city on a street food crawl.
Ride in style to Sihanoukville and board a boat to your own private beach on Koh Rong island. Take the afternoon to taste local seafood, or sit back and relax with a drink before hitting the warm waves.
Enjoy your last full day on this pristine island. Do anything you might have missed the day before, like fishing, hiking, or kayaking.
Head back to the mainland and journey to Chambok Village where you’ll spend the night and get to know the local people over a delicious Cambodian home cooked meal. Immerse yourself in the community and wander around this remote region.

Take this chance to visit the Ben Thanh Market for souvenirs and handicrafts before taking in the buzzing nightlife. Choose to venture to one of the many rooftop bars for a panoramic view and live music.
Feel the pulse of Vietnam’s biggest city on a CEO-led orientation walk, with free time after to double back to your favourite spots. Shop 'til your heart's content, immerse yourself in local culture, or just wander the streets to take in the city's unique vibe. Tonight, catch up on sleep on an overnight train to Nha Trang.
You’ve arrived! Welcome to the eastern sea. Take this morning to explore local shops and markets, rejuvenate in a therapeutic mud bath, relax on the beach, or visit nearby historical sites before an evening street food crawl.
It’s not over yet. There’s more free time to explore Nha Trang today, so soak it all in. Then, hop on an overnight train to continue to Hoi An, stopping first in Da Nang for a short transfer.
Hoi An’s excited to meet you. See why on an orientation walk of the city before spending free time in the afternoon. Dig even deeper and choose between a cooking class, cycling to the beach, visiting a tailor, or exploring old town. Tonight's the night for your big night out, to reminisce about your favourite adventures so far. Then dance the night away!
Noodles might be fun to eat, but they’re even more fun to make. Find out how during a visit to G Adventures-supported Oodles of Noodles. The rest of the day is yours, so see what you can discover. Choose to visit the ancient ruins of My Son, a UNESCO World Heritage Site, or cruise down the Thu Bon River.
Head north to the Imperial City of Huế. There’s lots to do here, with options to visit the indestructible Royal Citadel and tombs, cruise along Perfume River, or jump on a motorbike and ride around like the local people.
Your second day in Huế comes with more free time to enjoy the city. In the afternoon, travel through Vietnam's stunning countryside to the green rocky mountains of Phong Nha-Kẻ Bàng National Park.
Today, opt to head underground to explore the awe-inspiring caves of Phong Nha-Kẻ Bàng National Park, where the oldest karst mountains and longest cave in Asia are found. Then it’s an overnight train to Hanoi.

Feel like you've gone back in time with an orientation walk through Hanoi’s Old Quarter. Then stop for a drink at Bia Hoi Corner, a spot that serves bia hoi, a local beer made of rice and wheat - and costs a mere $0.25USD per glass!
A short flight brings the group to the capital city of Laos. Opt to visit temples, see the golden stupa of That Luang, or scour the markets.

Trek 2-3 hrs and, after lunch, head to a Karen village to see how to make traditional baskets and scarves. Continue trekking another few hours to the next village for the night.
