Koh Samui Flights

The islands of Thailand are known for their natural beauty, and Koh Samui doesn’t disappoint. Located around 700km south of Bangkok in the Chumphon Archipelago, this unique island offers sunshine and clear skies during the mainland’s wet season, and bursts with greenery when the rest of Thailand is in its dry season. Because Koh Samui just had to be different.

With an interior covered in rainforest and white sand beaches fringed with palm trees, Koh Samui is big enough for any island adventure you can dream up, and still small enough to make it around in a single day. So fire up that app with rainforest sounds to set the mood during lastminute.com.au’sflights to Koh Samui and get ready for the real thing!

Getting Around Koh Samui

Once you land, getting around the island is easy. It’s just a 20-minute minibus ride to Chaweng. You could also grab a taxi or one of our car hire options. Need more excitement? Try a motorbike instead and zip around the island with the wind in your hair. Maybe don’t tell Mum about that last bit.

When You Land…

Are you onKoh Samui flightsthat land in the morning? Spend the day at Namtok Hin Lat waterfall. Touching down in the afternoon? Check out Old House, a 200-year-old Chinese-style home.

If you land after dark, check out the mummified monk on display at Wat Khunaram Ko Samui. After that, it’s okay to sleep withthe lights on in your Koh Samui accommodation. We won’t tell anyone.

Live Like a Local

While the most developed stretch of shoreline is Chaweng Beach, the locals know that the northern beaches of Mae Nam and Bophut are far more peaceful.

Hungry? Try the village of Ban Lipa Yai, known for growing delectable fruits like mangosteen, langsat and durian. And you won’t even have to break your diet.

The secret to a great Koh Samui getaway might be quiet beaches and fresh fruit, but the secret to booking cheap flights to Koh Samui is lastminute.com.au. Add a hotel and to create personalised Koh Samui holiday packages, or just wing it when you get there. See you on the beach!
