Planning your first trip to Thailand? You’re in for an incredible adventure in the Land of Smiles! 

After spending several months exploring Thailand from the mountainous north to the tropical southern islands, I’ve put together this comprehensive guide to help first-time visitors make the most of their Thai experience.

Having travelled extensively throughout the country, I’ve navigated the bustling streets of Bangkok, meditated in ancient temples of Chiang Mai, and relaxed on the pristine beaches of Koh Lanta. This guide covers everything you need to know – from the best time to visit and ideal trip duration to must-see attractions and practical travel tips.

Whether you’re dreaming of sampling authentic street food, exploring ornate temples, or simply lounging on picture-perfect beaches, this guide will help you create an unforgettable Thai adventure. 

Let’s dive into everything you need to know for your first time visiting Thailand.

Discover how best to spend one day in Bangkok with my itinerary.

When should I go to Thailand

The best time to visit Thailand is any time of the year!

All jokes aside, if you want the best weather, go between November and February.

The temperature will be lower than April, May, and June, and you won’t experience such humid heat. When I visited in April, it was so hot and humid that I found myself taking so many shade breaks that it took away from the trip.

When I visited in September, there were days of rain, and it was gloomy and overcast most of the time.

However, in October we had loads of fine weather and could see it improving day by day.

How much time should I spend in Thailand

There’s no right amount of time to spend on a trip anywhere.

If you have a number of weeks to months, boy are you in for a treat.

Additionally, if you only have a number of days, you can still plan some fantastic outings and see some of the most beautiful parts of Southeast Asia, in my opinion.

Do I need a visa to visit Thailand

You will likely need a visa to visit Thailand.

However, for myself as an Irish citizen, I can enter Thailand for up to 60 days without a visa.

This has changed many times over the last few years due to COVID and the Thai government trying to encourage more visitors to make up for lost time. You need to keep an eye on your country’s government website for the latest information as it’s always changing.

In 2025, another change happened when all foreigners needed to apply for the Thailand Digital Arrival Card 3 days in advance of travel.

The best things to do in Thailand

I spent a few months exploring Thailand and it honestly blew me away. 

Every region has something unique, from stunning beaches in the south to peaceful rice terraces in the north. If you are planning a trip, here are the experiences I think you will absolutely love.

Relax on Thailand’s Beaches

Thailand’s beaches are incredible. This cannot be argued with. 

For me, the best beach was Long Beach on Koh Lanta because of the endless golden sands and stunning sunsets over the Phi Phi Islands. Meanwhile, Koh Phi Phi is totally different. You can expect boat parties, excursions, and water so clear it’s hard to believe it’s real. Another famous island, Phuket, has many good options but is more crowded. 

But you can find peaceful spaces away from the partying backpackers.

Trekking in Doi Inthanon

In the north, trekking into the tallest part of Thailand, Doi Inthanon, was special. 

It’s actually known as “the roof of Thailand.” You can see amazing rice terraces and spectacular views all around the region. I also spotted many waterfalls and bright green luminous snakes, which was fun. 

We also walked slowly through some of the tribal villages, where it was harder to find as many tourists.

Wandering the Night Markets

Thailand has the best night markets in my opinion. Chiang Mai and Ao Nang were my personal favourites.

 I could eat food from all corners of the world, but usually I would eat and recommend you try the sushi. It was great to see it all being prepared and cooked right there in front of me. You can pick up clothes and other handicrafts to take home for memories. Bangkok has so many great night markets too.

Snorkelling and Island Tours

Here is where it gets special. Krabi in particular is the best for snorkelling and scuba diving. 

On my Koh Phi Phi and Koh Lanta tours, we experienced some of the best waters, which gave Indonesia a run for its money. These longtail boats took us out in the morning, where we swam with amazingly colourful fish and could stay on the most exotic beaches afterwards. Make sure you bring a GoPro to capture all of the South’s best bits.

Exploring Rice Terraces

In the Chiang Mai and Chiang Rai region, you can experience some amazing rice terraces. 

It’s not just Bali that has them, folks. Incredibly, these large green fields stretch across the land and offer a peaceful way to spend time in Thailand’s northern region. If you’re tired of Bangkok or Phuket, you can make your way north and find calmness all around in nature. You can even discover how these lands are irrigated and see what life is like here as a local.

Discovering Thailand’s Temples

Thailand and temples go hand in hand. 

When I visited Bangkok, the Grand Palace and Wat Pho were strikingly beautiful. In Chiang Mai, you can see the white and blue temples which are insanely unique. You can expect to see many monks in their orange robes walking around calmly and smiling as they go. Every temple is different, and you can have some nice moments of quiet, which is rare these days, especially in Thailand.

Is Thailand safe for tourists

Thailand is one of the safest countries I have visited.

That includes my travels to another 12 countries in Asia.

The people are full of goodwill and will offer you help and assistance if you need it. Many locals who had nothing to gain have often made me feel welcome, and these warm encounters are commonplace.

How can I stay connected in Thailand

You can stay connected in Thailand easily.

Basically, you have two options:

You can purchase a physical SIM card at any 7/11 and have the staff install and set it up for you. When we did this, it took anywhere from 5 to 20 minutes, depending on how familiar the staff was with the process.

Another option is to get an eSIM. I have been using Airalo for three months in Vietnam and it’s great. It’s easy to set up and you can top up whenever you want.

Preparing for Your Trip to Thailand

Planning a trip is key to its success. Here are a few things that really helped me.

Pack for the Weather

It’s hot in Thailand pretty much any time of the year. 

Bring light and breathable clothes that quickly get rid of moisture. A light rain jacket will be your best ally in the rainy season. Make sure you cover your shoulders and knees when visiting temples, otherwise you won’t be allowed to enter. Oh, and don’t forget sunscreen!

Staying Healthy

You can have the cheapest and tastiest meals on the side of the street. 

But make sure you practice good hygiene when moving through Thailand. Your body may not be used to the atmosphere and it can affect people differently. Always wash your hands before and after eating. Use hand sanitiser. Drink electrolytes when feeling weak. Don’t like mosquitoes? Use repellent when visiting the countryside. All of these little tips can help you feel better and make the trip a success.

Money and Payments

Always carry cash with you. Night markets typically only accept cash payments. 

Fortunately, ATMs are widely available throughout Thailand, making access to money easy. Use your card for larger purchases, but I recommend cash for day-to-day expenses. Be aware that ATM fees in Thailand can be high, with each transaction costing up to six euros.

Getting Around

Tuk-tuks are the most enjoyable and fastest way to get around, while a car may be safer but slower. 

If you’re strapped for time, get a Grab or tuk-tuk. If you want safety and comfort, then get a taxi. I recommend downloading the Grab app, where you can order a motorbike or car and within minutes, you’re on the way to your next location. If you’re staying around the islands, expect comfortable ferries and longtail boats to move between the beautiful islands.

Respecting Local Culture

Don’t offend anybody. It’s up to you to learn about the culture before you go. 

I suggest smiling as much as you can. Number one, it’s nicer, and number two, people will react more positively to you and are more likely to help if you need it. Learning a few Thai words like “sawasdee” for hello and “khop khun ka/kap” for thank you always made locals smile back. When visiting temples, take off your shoes, dress modestly, and move quietly, as these places are sacred.

Final Thoughts/Conclusion

Thailand is an incredible place to travel. If it’s your first time, then you’re going to have your mind blown.

Amazing beaches, super cool temples, gorgeous rice terraces and tons more stuff to see, plus the food is just insanely good. You’re gonna love it!

Each region is different. My personal favourite was the incredible beaches in the south.

That doesn’t mean the rest of the country isn’t worth visiting.
