Khao Sok National Park in Surat Thani Province looks like it’s right out of Jurassic Park. Covering about 739 square kilometres, Khao Sok is home to lush rainforests, deep valleys, sparkling lakes, mysterious caves, and a whole lot of wildlife.
Ever wondered what a 160-million-year-old rainforest looks like? Khao Sok is one of the world’s oldest – even older than the Amazon. The park boasts a rich variety of flora and fauna, including rare species and unique ecosystems. Plus, don’t be surprised if you catch sight of wild elephants meandering near Cheow Larn Lake, all set against towering limestone mountains.

Besides sightseeing, there are heaps to do here for adventure lovers. Think jungle trekking, canoeing on Cheow Lan Lake, and exploring caves. But don’t worry about planning your trip – you can book a guided tour to make the most of your visit.
A popular option is the 2-day Khao Sok Jungle Safari tour. It includes a 3-hour trek through the rainforest, an overnight stay in a cosy bungalow, a canoe ride down the Khao Sok River, and even a visit to a hilltop temple. At S$544.50 per person, with transfers from and to Krabi included, it’s a pretty sweet deal for a full-on adventure.

For those who prefer to carve out your own adventure, here’s a tip: plan to spend at least 2 days at Khao Sok to soak it all in. You can even opt for a unique overnight stay at one of the floating raft houses, only accessible by longtail boat.
One popular choice is The Laguna Chiew Larn (฿13,000/night), about a 45-minute boat ride from Cheow Lan Dam Municipal Pier. Their Sea View rooms, which fit up to 4 people, and canoe rentals make for a laid-back afternoon on the lake.
Getting to Khao Sok National Park: Book a quick 1-hour and 35-minute flight to Hat Yai with Singapore Airlines or Scoot, then catch a bus from Hat Yai to the park.

Lampang, the capital of Lampang Province, is a charming city located about 100 kilometres southeast of Chiang Mai. Known locally as “Mueang Rot Ma” or the “Horse Carriage City,” it still offers rides in its traditional horse-drawn carriages – a nostalgic nod to simpler times that adds to its unique appeal.
But if you’re up for a stroll instead, Lampang’s old town is incredibly walkable. Wander through streets lined with centuries-old temples, quirky museums, and lively markets, each whispering stories of the once-mighty Lanna civilisation.

If you only have time to visit one attraction, let that be Wat Phra That Lampang Luang. It’s known as one of Thailand’s most revered temples. This masterpiece of early Lanna architecture features open-sided assembly halls with gold lacquered pillars and vibrant murals that showcase traditional craftsmanship. The temple is a key pilgrimage destination, especially for those born in the Year of the Ox, since it was constructed during that very zodiac cycle.
No entrance fee is required, though donations are appreciated. To get there from Lampang town, take a horse-drawn carriage (around ฿300), grab a taxi (roughly ฿170-220), or rent a scooter or car. The journey takes about 25 minutes one way, making it an easy and worthwhile visit.

Another must-visit, especially for animal lovers, is the Thailand Elephant Conservation Centre. This unique facility is dedicated to caring for and rehabilitating elephants – serving as both an elephant hospital and a training hub. It offers visitors a rare insight into the ongoing efforts to protect these majestic creatures. Psst, there’s even a 3-day mahout training course (฿24,060), where you can learn more about the elephants alongside their trainers.

One of the top attractions here is Chiang Dao Cave.

Kanchanaburi is a popular resort town in western Thailand. It’s best known for the Bridge over the River Kwai and the 130km-long Death Railway. Built during World War II by Allied POWs and Asian labourers under brutal conditions, this railway was meant to transport troops between Thailand and Burma, costing over 100,000 lives.
Fun fact: the Death Railway has been featured in literature and film – including the famed 1957 classic The Bridge on the River Kwai, although that was filmed in Sri Lanka.
Besides its historical lore, Kanchanaburi is a haven for outdoor enthusiasts. One spot you can’t miss is Erawan Waterfall, tucked away in Erawan National Park, famous for its 7 tiers of cascading water and refreshing emerald ponds. The park, named after the legendary 3-headed white elephant of Hindu mythology, even features a top tier that some say resembles an elephant head.
Erawan National Park isn’t just about waterfalls – it’s a mix of mixed deciduous forests and dry evergreen woodlands, with limestone hills, plains, and meandering streams. The park also boasts several caves scattered throughout the area for the more daring ones to explore.

For those who prefer a bit of hiking with a view, head over to the John Suwan Viewpoint. Located at the southernmost tip of the island, this viewpoint offers panoramic scenes of Koh Tao, with Chalok Baan Kao Bay on one side and Shark Bay on the other.
The hike is a moderate 500m climb that takes about 15 to 20 minutes. You’ll need to navigate some rock scrambling near the top, but ropes are provided to help with the steeper parts. Entrance is just ฿50-100 per person, which is all worth it for the views you get.
Getting to Koh Tao: 1-hour and 55-minute flight to Koh Samui via Scoot or Bangkok Airways, followed by a ferry from either Bangrak Pier or Maenam Pier to Koh Tao. The ferry ride takes about 1.5 to 2 hours.
If, like us, you’ve always wanted to be part of The Wild Thornberrys growing up, Koh Yai National Park is a great nature park in Thailand to add to your bucket list. This UNESCO World Heritage Site spans roughly 2,168 square kilometers, featuring tropical seasonal forests and grasslands, including one of mainland Asia’s largest intact monsoon forests.

Once the capital of the Kingdom of Siam, Ayutthaya is now a UNESCO World Heritage Site brimming with historical ruins. Often seen as Thailand’s alternative to Cambodia’s Angkor Wat, this ancient city offers a fascinating glimpse into a once-thriving metropolis that ruled for over 400 years.
Explore Ayutthaya Historical Park by cycling or strolling among its ruins. The park sprawls across an island surrounded by the Chao Phraya, Pa Sak, and Lopburi Rivers and is dotted with 425 archaeological sites, including temples, palaces, and crumbling monuments.

An essential stop is Wat Phra Si Sanphet, a former royal temple that once held the title of the holiest site during the Ayutthaya period. Its 3 towering chedis perfectly capture the classic architectural style of ancient Siam and are a real treat for any history buff.
Don’t miss the Chao Sam Phraya National Museum, which houses an impressive collection of artifacts recovered from Ayutthaya’s temples and palaces – ranging from exquisite Buddha statues and ceramics to royal regalia and golden offerings. Entrance costs just ฿30, but it’s the perfect treasure trove of ancient Siamese art and culture.
Getting to Ayutthaya: A 2-hour and 25-minute flight to Bangkok, then hop on a train or bus from Hua Lamphong Train Station to Ayutthaya – usually about 1.5 to 2 hours, with departures throughout the day. If you prefer a more direct ride, a taxi or ride-sharing service will get you there in roughly the same time, traffic permitting.
