The currency in Thailand is Baht and the exchange rate is approximately $1 USD = 30 Baht.

Getting a tourist sim card for your trip to Thailand is very simple. You can obtain a sim card upon arrival at the airport or from a 7-Eleven store. The cost of a tourist sim card for 8GB of data is around $15.


When planning a trip to Thailand, it’s good to know that it can be visited all year round as the climate can vary.

However, the best time to visit is in the cool dry season between November to early April.

Broadly speaking, Thailand’s wet season is April – October, with the wettest months being August – October.


Thailand currently offers visa-free entry to nationals of 57 countries. The free visa on arrival is valid for 30 days in Thailand. For more visa information visit www.thaiembassy.com.


There are a few ways of getting around Thailand and that is with either bus, boat, taxi, train, plane, or motorbike.

In my experience, the cheapest and most convenient way of getting around Thailand is by bus. The most reputable bus/boat company is Lompraya transport.

I always use 12Go Asia to search and book all of my transportation within Thailand.

Koh Tao is my favorite island in Thailand and one of the best tropical destinations in all of South East Asia!

Koh Tao is the famed diving haven in Thailand and attracts scuba divers from all over the world. Ultimately, it should not be missed on your southern Thailand itinerary.

I highly recommend taking a day trip from Chiang Mai to Chiang Rai to visit the famous White Temple and more.

Chiang Rai is worth visiting for so many reasons, and you’ll easily understand why.

I organized my Chiang Rai day trip with a tour company called Take Me Tour which includes all transport, entrance fees, lunch, and an experienced tour guide!

The Chiang Rai Tour was surprisingly one of the best days I had while backpacking Thailand.

I chose the Chiang Mai to Chiang Rai tour package which includes Mae Kajan Hot Spring, The White Temple, lunch at Salungkham restaurant, Doi Tung Botanic Gardens, The Royal Villa, and a visit to the Akha Hill village tribe.

The Chiang Rai tour starts at 7 am with a hotel pick-up in Chiang Mai and returns back to Chiang Mai between 8 pm – 9 pm.

Back to Bangkok to enjoy the last day in Thailand! You can choose to go shopping at one of the malls or hit up Koh San road for some street food and cheap beers. Either way, it’s worth celebrating having just completed your Thailand backpacking route!

If you don’t want to travel all the way back to Bangkok from the north of Thailand, there’s the option to depart the country from Chiang Mai International Airport.
