About this trip

Trip inspired by Gap 360's "Thai Adventure - 25 days" route, generated independently with the operator margin removed — not booked with or affiliated with Gap 360. Setting my own date, looking for trip mates to join. Experience the full Thailand loop independently — from the buzzing streets of Bangkok and the cultural heart of Chiang Mai, through the jungle of Khao Sok, and out to the legendary island paradise trail of Phuket, Krabi, Koh Samui, Koh Phangan, and Koh Tao. This self-guided itinerary replaces group tour mark-ups with local transport, self-bookable activities, and handpicked budget accommodation — delivering the same adventure for a fraction of the price. All costs are approximate estimates per person.
