The Land of Smiles is a beautiful country with an incredibly diverse culture and an affordable food scene. It’s easy to see why Thailand is consistently one of the world’s most visited destinations.
If you’re thinking of travelling to Thailand in 2026, check out our guide for a clear roadmap on what to organise before you leave, what to pack, when to travel, and how to shape an itinerary that makes your getaway smooth and memorable.
What to Sort Before You Fly
Thailand has introduced a key change for visitors: from 1 May 2025, all foreign travellers must complete the Thailand Digital Arrival Card (TDAC) online. It must be submitted within 72 hours before arrival, replacing paper arrival cards and promising to speed up immigration checks.
British tourists benefit from visa-free entry for stays of up to 60 days, making holidays and extended trips easy to manage. However, you must meet other entry requirements. Your passport must be valid for at least six months from your date of entry, and you may be asked to show a return or onward ticket. Immigration officers can also request proof of funds, so it’s best to have recent bank statements or evidence of accommodation bookings on hand.
Review the latest UK government travel guidance before you fly, as entry rules or safety information may change. Organising essentials early prevents last-minute surprises at the airport and ensures a smooth arrival.
When and How to Go
Thailand is famously a year-round destination, but the best time to visit is from December to March, thanks to its comfortable temperatures and low rainfall. It’s also peak season, meaning flights and hotels cost more and major destinations get busier. The heat intensifies from April to June, while the monsoon varies by region (roughly from May to October).
Since Thailand holidays vary by season, checking climate patterns helps manage expectations for crowds and trip costs. Pay attention to health and safety advice, including any regional alerts on weather, political events, or travel restrictions, before travelling. Thailand is generally safe for visitors, but awareness is key to avoiding disruptions.
Must-see Destinations & Experiences
Most travellers start with Bangkok, a vibrant gateway with temples, markets, rooftop bars and easy connections to the rest of the country. Spend two or three days exploring highlights like the Grand Palace, Wat Arun, glistening malls, and the city’s famous street-food neighbourhoods.
For culture and scenery, Chiang Mai and Chiang Rai in the north offer temples, night bazaars, elephant sanctuaries and mountainous landscapes. If beaches are a priority, head south to islands such as Phuket, Koh Samui, Koh Phi Phi or Koh Lanta. Each has its own atmosphere (some lively, some quiet), so choose based on whether you want nightlife or peaceful lounging.
If you prefer something more offbeat, islands like Koh Yao Noi, national parks such as Khao Sok, or historic towns like Ayutthaya add depth and variety to your trip.
