3 Weeks in Thailand Budget

Before you travel around Thailand in 3 weeks you need to make sure you have a good budget in mind. Keep in mind you need to include food, water, drinks, nightlight, tours, day trips, souvenirs, planes, buses, and grab rides.

The budget for a three-week Thailand itinerary can vary depending on your travel style, accommodation choices, activities, and food preferences. However, here’s a general breakdown of the costs you can expect:

Stay, Food, Transportation, & Activities for Three Week Thailand Itineraries

• Accommodation: The cost of housing in Thailand is always affordable. But can vary depending on your preferences. You can find budget guesthouses and hostels for as little as $10-$15 per night, mid-range hotels for $30-$50, and luxury hotels are still affordable for around $100.
  
• Food: Thai street food is affordable and delicious, and you can find a meal for as little as $1-$2. If you prefer to dine in restaurants, you can expect to pay $5-$15 for a meal. Western food and fine dining restaurants are a bit more expensive. You can get a full meal with drinks and spend about $20 per meal.
  
• Transportation: Renting a scooter is the most popular way to travel around Thailand. If you are not into that vibe next are Tuk-tuks and taxis. Grab, Maxim, or Bolt are the best ride-sharing apps. You can expect to pay about $2-$7 for a short ride. The downfall of a car is that you will sit in more traffic than a bike. Pro tip- downland Grab BEFORE you get to Bangkok, and put in your banking information.
  
• Activities: The most expensive part of your trip will be the entrance fees to popular attractions like temples and national parks. These fees can range from $1-$10 depending on what you like to do.
  Activities like cooking classes, elephant sanctuaries, and island hopping tours can cost anywhere from $30-$100 or more. It is best to book them now so you can budget better for your trip.

Overall, a budget of around $1,500-$2,000 per person (excluding international flights) should be a good start for traveling around Thailand for 3 weeks. Assuming you go with affordable accommodation, local food, and a few activities.

Best Ways to Travel Thailand in 3 Weeks

So this is kind of personal, and depends a lot on your budget, and how spontaneous you want to be. There is a great site called 12go.asia that will help you plan out your movements for your Thailand travel itinerary 3 weeks.

There are long overnight buses to take from Chiang Mai to Krabi, or Bangkok to Chiang Mai. These will take up more of your time during your 3 week travel itinerary Thailand but will save you some money.

A quick way to travel is with domestic flights which can cost anywhere from $10-$80. The sooner you book the better the price is.

Long-distance buses can cost around $10-$20, you can book these buses online before you come, but I have found it better to find a little “travel booth” and just ask them what they have available. In most places, wherever you rent your bike from should be able to help you.

The same methodology goes with booking your boat tickets. You can book them before or do it when you get islands. I have done both and the prices seem a bit cheaper in person, but when you book online you have a sense of mind that it is all done.

See Bangkok in 4 days

We will start your 3-week Thailand itinerary from Bangkok. Plan to spend 4 days here to really get the feel for everything. Bangkok is amazing and you will love the feeling of this giant city.

Day 1 in Bangkok: Arrival and Exploring the City

• After arriving in Bangkok, check in at your hotel and freshen up before heading out to explore one of the biggest cities in the world! I always take a grab from the airport. If you are flying into BKK the Grab pickup station is on level two where all the taxis meet, you cannot miss it. You can also book a private pick-up, which I have also done a few times and can recommend.
  
• Start with a visit to the Grand Palace, which is located in the heart of Bangkok. The palace is the official residence of the Kings of Siam and includes several buildings, temples, and courtyards, all adorned with intricate and colorful decorations.
  
• Next, visit Wat Phra Kaew, the most important Buddhist temple in Thailand, and home to the famous Emerald Buddha. The temple is located within the grounds of the Grand Palace and is a must-visit attraction in Bangkok.
  
• After exploring the Grand Palace and Wat Phra Kaew, take a walk around the nearby Rattanakosin Island. The island is home to several other historic sites, such as Wat Pho, the Temple of the Reclining Buddha, and Wat Arun, the Temple of Dawn. If you wanted to book a temple tour, this one comes highly recommended.

Day 2 in Bangkok Boat Rides

• Start the day with a leisurely breakfast at your hotel, and then take a boat ride along the Chao Phraya River. The river runs through Bangkok and is an excellent way to explore the city’s sights and sounds from a different perspective. Book a tour for a historic boat ride!

• After returning to Bangkok, spend the afternoon shopping at the Chatuchak Weekend Market. This is the largest open-air market in all of Thailand. You will find a wide variety of products. From new and used clothing, the cutest accessories, home decor souvenirs, street food, and even antiques. It’s a great place to shop to grab your loved ones’ authentic gifts.

Day 4 Bangkok to Chiang Mai

Today is a travel day, so I always like to leave those days light. Grab some local food or splurge and order grab straight to your hotel room and just take it easy before your travel day. To get to the airport or bus station, I always book a grab. Do not let them tell you to pay the tolls, or that you have to use the meter.

Where to stay in Bangkok
