• Welcome Moment - Meet Your Expedition Leader and Group

Step onto a boat heading down the Chao Phraya River toward Tha Tien Pier to begin your morning. Walk to the grand grounds of Wat Pho to see the massive Reclining Buddha, then take time to wander the bustling food stalls nearby. In the afternoon, board a traditional longtail boat to navigate the historic waterways, slipping from the main river into the quiet, wooden-built canals of the Thonburi district. Here, daily life unfolds right along the water's edge: laundry dries in the sun, kids splash from docks, and vendors paddle past, showing you a grounded, local side of the city before you head back for a free evening.

Leave the capital behind and head toward Kanchanaburi, where the Khwae Noi and Khwae Yai rivers meet.

Venture into the lush canopy of Erawan National Park to find the famous seven-tiered waterfall.

After a morning at the falls, travel across the green plains to the ancient capital of Ayutthaya. As dusk falls over the old city, climb aboard a beautifully converted 1930s rice barge for a dinner cruise. Drift past ruins and riverside villages while sharing a traditional meal, watching the stars come out over the water before checking into your hotel.

Step into the home of a local family for a Khantoke dinner, passing platters of sticky rice, rich hang-le curry, and crispy pork with chilli paste. After dinner, walk through the garden, sip tea, and learn more about rural Thai life before checking into your hotel.

Dive into the smells and colours of the neighbourhood market this morning, picking out fresh ginger, lemongrass, and chillies alongside local shoppers.

In the afternoon, meet with monks at Wat Suan Dok temple, before riding a cable car up the mountain to Wat Phra That Doi Suthep. Listen to the monks' evening chanting, then join a talk at the International Meditation Center with a teaching monk about Buddhist life, the remainder of your evening at leisure.

Step aboard a traditional longtail boat on an excursion with a community-run enterprise, supported by G Adventures. Cruise the waters of the Andaman Sea, heading for the Hong Island archipelago. Spend your day exploring four islands: Hong, Pakbia, Lahding, and Paradise. Sink your toes into white sand, share a quiet picnic lunch surrounded by limestone cliffs, and snorkel in clear waters teeming with colourful marine life. It is a day defined by the simple rhythms of the sun and sea, offering plenty of time to swim, relax, and absorb the natural beauty of the coast before heading back to Krabi for a free evening.

• Island hopping by longtail

Begin the morning by crossing the Krabi River on a longtail boat to explore quiet rural communities. Hop on tuk-tuk to wind through farming villages, meeting residents and learning about daily agricultural life and the customs of the predominantly Muslim community. In the afternoon, travel to Khao Sok National Park, where you will join a local guide for a walk through the rainforest. Arrive at a secluded jungle clearing for a bamboo cooking experience, helping to prepare a feast of green curry, barbecued chicken, and rice inside freshly cut bamboo tubes, dining as the forest comes alive with evening sounds.

Today is yours to shape as you wish, with optional excursions that let you dive deeper into this ancient rainforest. Choose to set out on a guided jungle trek to spot wild orchids, towering bamboo groves, and signs of native wildlife along the leafy trails. Alternatively, opt for a peaceful canoe tour down the gentle Sok River. Whatever you choose, spend a slow-paced day connecting with one of Thailand's most biodiverse wilderness areas.

Discover how delicious southern Thai dishes go from plot to plate at Kao Thep Pitak farm and restaurant, a G Adventures supported community-run project. Walk through organic orchards and a nearby rubber plantation, learning how this self-sustaining initiative supports more than 140 local families. Share lunch prepared by village members, then travel to Don Sak pier to board the afternoon ferry to the tropical island of Koh Samui. Arrive on the island and settle into your hotel for a relaxed evening.

• Harvesting local traditions

Set out on a day of discovery across Koh Samui, travelling beyond the beaches to see the island's interior. Wind past coconut plantations, wander jungle sanctuaries, and stand before waterfalls and island temples. Along the way, take in sweeping panoramic views from high mountain lookouts and stop to feel the soft sand of quiet Silver Beach. This journey offers a balance of culture, local life, and natural beauty, ending with a relaxed evening at your leisure.

• Hidden corners of Koh Samui

Spend a free day taking in Koh Samui at your own pace. Choose to spend the day relaxing on the sun-warmed beaches, dipping into the Gulf of Thailand, and browsing local seaside markets.
