Choosing between a holiday on Phuket or a trip to Koh Samui is like choosing between a pot of gold and a pile of money – you can't really go wrong. Package holidays to Phuket and Koh Samui offer you the chance to immerse yourself in Thai culture, experience an outdoor adventure, or simply relax on some of the most beautiful beaches in the world.

We would never leave the decision up to you, so the experts at Expedia Australia have done the research for you. Here are some unforgettable impressions to help you choose between these two enchanting islands.

Phuket, connected to the Thai mainland by the Sarasin Bridge – an attraction in itself – is an incredibly popular tourist destination, and rightly so. One day you can soak up the sun on a secluded beach like Nai Harn or Kata Noi, and the next day join other holidaymakers for the local festivals on Patong Beach. For those seeking a bit more adventure, you can hop on a stand-up paddleboard or rent a pontoon boat and head out to one of the rocky reefs in the Andaman Sea.

Afterwards, rent a scooter and explore Phuket in search of local culture. Easily visit museums that illuminate Thai history, as well as Buddhist temples with their colorful, intricate statues. Later, experience how culture and performing arts merge in the graceful movements of Thai dance. You can watch a performance or try a few steps yourself.

If you truly want to get to know the warm and welcoming people of Thailand, volunteer at a language school during your visit. Who knows, you might even get some insider tips for delicious southern Thai cuisine. Another tip: A traditional Thai massage – ideally on a western beach at sunset – is a wonderful way to experience the local culture firsthand.

Koh Samui lies off the east coast of Thailand in the Gulf of Thailand and is the country's second largest island. Although only recently developed for tourism, it offers a rich Thai history and a variety of outdoor activities. Hike through the rainforest – or take an elephant ride if you prefer – and discover hidden waterfalls or the Secret Garden, a collection of Buddha statues carved by local farmer Uncle Nim.

Koh Samui is a tropical island, and you'll most likely spend your time on secluded beaches like Silver Beach and Lamai Beach. If you're looking for a bit more excitement, check out the shops, restaurants, and nightclubs on Chaweng Beach in the northwest of the island. Or, learn about Koh Samui's history by spending time with a local fisherman. They still fish using the same methods as generations have, and you'll have the opportunity to support the fishing village's conservation efforts.

Speaking of fishing: Koh Samui boasts some of Thailand's best seafood. Be sure to try the pickled and fried Pla Som Tod. Looking for local art for your home? Take a batik painting class and create your own Thai masterpiece. If you need inspiration for your own creative projects, visit the Big Buddha at Wat Phra Yai or the 18-armed Guanyin at Wat Plai Laem.

Both islands are so beautiful that you'll probably be just as undecided as before. But that's no problem. You can visit both – after all, you don't have to choose just one!
