Know this before going to Thailand..
1 Currency: Thai Baht (THB) (current exchange rate) Power: 220V / 50Hz (North American plug and round two-tier)
2 Primary Airports: Bangkok's Suvarnabhumi Airport (BKK), Chiang Mai (CNX), Phuket (HKT)
3 water: not safe. But the water served in restaurants in jaggery is always filtered. Use SteriPen or LifeStraw if you can't drink bottled water, especially in rural areas.
4 Internet status: Thai Internet is very reliable. It is not the fastest in the world, but it works, and most cities can also promise good uptime. If your hotel internet does not work, you can find a dozen or more cafes in the city with good speed and delicious coffee. Nomadic Notes has a great collection of WiFi-friendly cafes in many cities in South-East Asia.
5 Visa: Generally, a passport from the U.S., U.K., and the European Union is given a free for 30 days as a tourist if you go by air, and 15 days if you enter overland Huh. Check your visa requirements here. And below I outline how many passengers stay longer on dual-entry and student visas.
6 Festivals of Note: Loy Krathong in Chiang Mai is notable in late fall. Bo Sang Umbrella Festival, Chiang Mai (January). Chiang Mai Flower Festival (February). Songkran Water Festival (April), Hua Hin Jazz Festival (June), Vegetarian Festival, Phuket and Bangkok (September / September)
7 Security: The entire Southeast, is a very safe region of the world. This is actually one of the first places I recommend for solo and new travelers. Thailand has the most developed tourism network in the region and is typically the hub of backpacking trips in SEA. If you are not cautious then opportunistic crimes like theft and pickpocketing will certainly happen, but violent crime against tourists is very rare. There are also scams (see the "Potential issues" section). Traffic accidents are the biggest threat here, not crime. Anything can happen on the road. I am a firm advocate of travel insurance like World Nomads; For a full review, these are my top tips for getting a good travel insurance.
8 Food Ideas: Thailand has amazing food options for travelers from every ilk. You can easily find a vegetarian diet with just a few words under your belt. If you are a meat-eating person, Mark's site is the best guide to eating in Thailand. In addition, you should make a complete plan to eat street food options, so follow these food safety principles. The Personal City Guide has additional restaurant recommendations for vegetarian travelers.
9 Local SIM: Getting service for your phone is a cinch, and it's cheaper to boot. Read this sim card guide for tips on how to get, how to top up, and what the whole process will be like.
10 Accommodation: Links in the city guide go to a hotel booking site below, many are found on Airbnb if you are a member. (Little Adrift readers get AirBnB credit here to give it.) When you're in Southeast Asia, Agoda is the best booking site. When they provide accommodation worldwide, their coverage and reviews are among the best in SEA. Although I use Agoda for a lot of my bookings, Booking.com is a solid backup of options and reviews, and has a discount bonus incentive on your first booking if you sign up via A Little Adrift. If you need some more help navigating where to stay each night, check out my detailed guide to finding good places to stay.
11 Transport: Thailand has a well-developed transportation infrastructure. If you want to go there, you can make sure that there is a way to do this on public transport. There is a network of trains (these are the slowest transport options, but are cheaper), and an extensive network of long-distance buses that carry rockets to every corner of the country. Within the cities, you can take buses, taxis, Geethe (shared public truck-taxis), and tuk-tuk. That being said, traffic accidents are a major problem and have a high death rate. Be careful, especially if you are renting a motorcycle and are not familiar with road customs. Uber works in big cities (although it arrives and local authorities crack down on it). I have a comprehensive page dedicated to transportation in Thailand, which covers how to travel to major cities and sightseeing, as well as other places in Southeast Asia.
12 Budget: Once you're on the ground (excluding flights), backpackers universally charge an average of $ 30 per day, this as both solo and doubles passengers. Every day there are slight fluctuations. Compared to the Thai islands it is cheaper in the north, but the overall basic budget is around $ 30 if you plan to travel. If you are truly going backpacker style. You can do a lot of bang for your buck at an average of about $ 40-50 a day. This means some good digs (probably with A / C), and of course if you eat street food every day.
