Southeast Asia Itinerary – Starting In Thailand

June 17, 2025

Bangkok is a huge flight hub in Southeast Asia with good connections to Europe and London. You can also fly to Bangkok cheaply and easily from just about anywhere in Asia on the budget airlines. It’s the perfect place to start your explorations of Southeast Asia. Here we’ll give you a three-week itinerary to see the best of these three countries.

This is just one possible itinerary for Southeast Asia, there will be many more on this site!

A Thailand, Malaysia and Singapore route is a great introductory itinerary for first-time visitors, giving a good diversity of food and cultures. There are plenty of beach opportunities if you want that, plus travel is easy in these destinations. These are 3 of the easiest countries to travel in Southeast Asia, they are all very modern and wealthy in parts, and they all have direct border crossings.

There are internal and international flights as part of this itinerary, they are short and cheap. Our cheapest flight ever in Southeast Asia was just $12, KL to Krabi. Bargains like this are out there!

Things To Know Before Planning Any Itinerary For Southeast Asia

  1. When’s the best time to visit this region? You’ll want to avoid the worst of the rainy seasons, and times when there may be flooding, and possibly extremely hot times of year. We wrote a full guide to best times to visit all of the countries in Southeast Asia here, briefly, for this itinerary, October is the start of peak season in Thailand, with good weather through to the end of February. You may also want to catch some local festivals, there are a lot, and they’re all worth seeing. The Best Festivals in Southeast Asia are on our list, here. If you’re travelling with young children think carefully about crowds and if your kids can handle them. Christmas is a good time, but hotels will probably be more expensive and booking more difficult. Lunar New Year is early in the year, check the dates. The dry season in Malaysia and Singapore is later, February, March and April being the best months. In Malaysia the dry season is around June. I would probably choose February as the best time to visit all 3 countries, but don’t worry about the weather too much. We have driven all around mainland Malaysia and toured Borneo in February, and saw no rain!
  2. Think about visas in advance. You can check visa regulations for Southeast Asia here at IVISA.
  3. Consider any travel vaccinations you may need, or health advisories, well in advance.
  4. If planning all of this travel sounds like too much hassle, or maybe you’re a solo traveller and would enjoy some company, book a small group adventure tour, there are plenty to choose from in Southeast Asia.
  5. When you book your major international flights, remember that they are often cheapest about 3 months before departure, there is no need to plan further in advance, and you can certainly book everything last minute, or as you go. You do not need a travel agent.

Thailand Itinerary

Dawn over Bangkok Southeast Asia
Dawn over the city of Bangkok. We took this photo on top of “The Golden Mount”. If you can get out for a walk before breakfast, do it!

1. Arrival in Bangkok, Plus 3 Full Days in The City

You will arrive in Bangkok by air at one of the two main city airports, Suvarnabhumi, BKK (pronounced su-wanna-poom) or Don Mueang DMK. BKK is connected to the city by the Airport Rail Link (ARL), DMK is an older airport, and is not, you’ll have to travel into Bangkok by road.

The local budget airlines usually use DMK, international travellers from Europe, the USA and the Middle East are more likely to arrive at BKK, it’s a nicer airport with better facilities. DMK is a little closer to the city centre, 22 km away vs 28 km out.

How will you get from the airport to the city or your hotel? You can take the train, although we never have in the 30 or so times we’ve arrived in Bangkok. Taxis or transfers are easier and usually cheaper for a family. The roads are usually busy in Bangkok. Your taxi driver will ask you if you’d rather use the highway and pay the tolls, or take the extremely slow route. Pay the tolls! They’re inexpensive. You will need Thai Baht in cash for this, get some out at an ATM inside the airport.

If you don’t want to wait your turn at the taxi ranks and would rather use the faster tollway without dipping into your cash, book a transfer. Book a transfer from BKK here, and from DMK here. If you prefer, you can book these through the Asian platform Klook, if you sign up we can send you a 10% discount code.

Allow at least an hour for the journey. Check in at your hotel, if you can, if not, drop your bags and start exploring!

  • Where will you stay in Bangkok? You need a convenient location, near the main attractions. This hotel is a lovely 5-star choice, on the river. For a more moderately priced stay (with family rooms) try here. For a fairly budget stay, check out this gem! We love this location and usually stay in this area ourselves.

Things To Do And See in Bangkok

This is a very short taste of Bangkok, in an ideal world, you should stay at least a week, but to see the main sights, do the following. Remember, this site is family-friendly, so we won’t be including excessive nightlife here. Bangkok is one of our favourite cities in the world, there’s so much to enjoy here!

The major, unmissable sights of Bangkok are the Grand Palace, Wat Po, and Wat Arun. The easiest way to see these, all in one day, is to take a tour. There are hundreds more beautiful places, Wats and Temples in Bangkok. Exploring on foot, just getting lost in the old part of the city, is our recommendation, but time is short, so we book this tour, with a guide. This will take up one full day.

Chinatown Bangkok is home to the biggest solid gold Buddha in Thailand. Maybe visit in the afternoon so that you can proceed to the bustling street food night markets of this part of Thailand. To find the Michelin guide food stalls, you’ll need to book this evening tour.

Floating Markets are a big draw for visitors to Bangkok and there are several nearby. The one most tourists see, Damnoen Saduak, is a bit of a tourist trap but it’s open daily, some of the better ones are weekend markets.
There are loads more things to see and do in Bangkok, for a much longer list visit our sister site for our Bangkok guide.

2. Overnight Train Travel to Chiang Mai (or Fly)

The overnight sleeper train to Chiang Mai is a classic rail journey and an experience in itself. For the budget-conscious, it also saves you the cost of one night in a hotel. If you’d rather fly to Chiang Mai, it’s a very short hop, but we love this train. It gets you to Chiang Mai very early in the morning, you’ll have a full day to explore. You can book the train, a flight, or a bus between Bangkok and Chiang Mai here.

The new train station in Bangkok is close to Chatuchak Weekend Market, this huge market appeals to some, but for us it was very missable, there are better places to shop in Bangkok. There is better shopping in Chiang Mai’s markets, too.

  • Where to stay in Chiang Mai? You should stay within the walls of the stunning old town. Most of the places that you’ll want to see are in this area.

3. Full Days in Chiang Mai

Just ONE of the stunning temples in Chiang Mai. There is an entry fee for this one, but many are free to visit, we’ll give you a quick list of the best below.

Things To Do and See in Chiang Mai

Chiang Mai is famous for incredible temples, some of the most breathtaking in Southeast Asia are here. There is also trekking and Hill Tribe visits, elephant sanctuary daysd, beautiful countryside, cooking classes and many night markets and walking streets. It’s a wonderful place, but not in burning season! Then air quality plummets. At least try to do and see the following.

4. Fly To The Beach

You’ll need to fly south from Chiang Mai and this makes it the perfect point in the itinerary to fly to a beach destination. Phuket, Koh Samui and Krabi have airports and all are popular beach locations. There’s not a huge amount of cultural interest at any of these places, but if you need some sun and sea, just relax for a few days!

Spend as many days as you like at the beach. Both Krabi and Phuket, being on opposite sides of a body of water, give you access to stunning scenery and snorkelling, including Phi Phi island.

5. Onward Flight To Malaysia

You will be flying out of your beach location and on to Kuala Lumpur. While a rail crossing into Malaysia is possible, it’s not normally advised.

Malaysia Itinerary

1. Arrive in Kuala Lumpur By Air, 2 Full Days in KL

2. Ipoh

Ipoh is well-known as a foodie destination in Malaysia. It also has The Lost World of Tambun water park, this may make your kids happy!

We like Ipoh, it’s a nice town with cute colourful shophouses, rock temples and gardens. It’s on the bus route from Kuala Lumpur to Penang, so if you fancy it, stop for a day or two. If not, skip it. But it’s nice to get a more rounded impression of Malaysia and see different places.

We think Ipoh is much nicer than the Cameron Highlands; to us, that place wasn’t worth visiting.

3. Penang (Not Langkawi)

Why Penang not Langkawi? We like Penang, we did not like Langkawi very much. Penang has more to offer, it still has beaches, but also more places of interest like the incredible (live) snake temple or beautiful Kek Lok Si. For a beach vacation stay in Batu Ferringhi, for culture and history lovers, stay in Georgetown. Don’t miss Fort Cornwallis, Little India for food, and the famous street art in Georgetown.

Penang has its own airport, so you could fly back to Kuala Lumpur cheaply on AirAsia, or return by road and travel on south to beautiful Melaka. The island of Penang is connected to the mainland by a road bridge, so you don’t have to worry about Malaysian ferries. We were on one that broke down once.

If you have your heart set on Langkawi, do it, always travel your way, not somebody else’s way. You can fly or take the ferry. You can see

4. Melaka

5. Johor Baru For Legoland Malaysia

6 Bus (or Fly) To Singapore

Singapore Itinerary

If you’re on a tight budget, we’d suggest you keep your time in Singapore short. Hotels here, even on the budget end of the scale, are expensive. Some of the luxury hotels are fairly affordable by some standards. If you’d prefer a 5-star stay, check out The Fullerton Hotel, it’s more affordable than Marina Bay Sands (the boat-shaped hotel high on a skyscraper). The location of each is ideal.

We stayed at The Fullerton ourselves recently (more info on our experiences here) and loved the historic building and rooftop pool with river views.
