Malaysia

One of the contributions the Japanese made to Borneo during WWII, Poring Hot Springs has become a popular weekend retreat for locals. The complex is part of the Kinabalu National Park, but it's 43km away from the park headquarters, on the other side of Ranau, with its own accommodation options.

If there's a more thrilling cocktail of Asian cultures than in Penang, we've yet to find it. Penang has long served as the link between Asia’s great kingdoms and an important outlet to the markets of Europe and Western Asia. At its heart is diverse, cosmopolitan George Town, Penang Island's main city and an urban centre that delivers old-world Asia in spades, from trishaws pedalling past watermarked Chinese shophouses to blue joss smoke perfuming the air. The freshest aspects of modern culture are present, too, in the exceptional art scene and free-spirited carnivals, all fed by an infectious local enthusiasm for Penang's long history and kaleidoscope of cultures.

For many visitors, a journey to Peninsular Malaysia's largest state begins and ends on the enchanted isle of Tioman. Between its exhilarating diving, brilliant beaches, vegetation-choked jungle treks and spirited villages, its tropical-island allure is impossible to resist.

The northernmost major city in Malaysia is also one of its most devoutly Muslim and it is deeply grounded in traditional Malay heritage. Kota Bharu has all the energy of a midsized city with the compact feel and friendly vibe of a small town. There are excellent markets and ample opportunities to taste superb local cuisine. There is also a good spread of accommodation options from backpacker hostels to business hotels. This is a logical overnight stop between Thailand and the resort islands of neighbouring Terengganu: Perhentian and Redang.

Perak's second-largest town is defined by water and greenery. Locals laud it as the 'City of Peace' for trailblazing Malaysia’s first museum, first railway and first newspapers in English, Malay and Tamil. But it’s Taiping’s ‘Rain City’ title that has stuck. Taiping has the biggest volume of rainfall in Peninsular Malaysia: all the better for its verdant lake gardens (and the pastime of 'rain betting', where locals take a punt on what time downpours will start and stop).

Sitting like an emerald dragon guarding the translucent waters of the South China Sea, Tioman Island offers every possible shade of paradise. There are cascading waterfalls, rigorous jungle hikes that take you past hibiscus blooms under an evergreen canopy, and a wide range of laid-back villages facing idyllic beaches. And then there's the gorgeous sea of greens, blues and chartreuse swirls that beckons you to paddle, snorkel, dive and sail.

A visit to the world's most famous place to see orangutans in their natural habitat is all the more compelling thanks to the outdoor nursery for orangutan youngsters in the same complex, and the nearby Sun Bear Conservation Centre and Rainforest Discovery Centre. In addition, the Labuk Bay Proboscis Monkey Sanctuary is only a short drive away.

Sabah occupies a relatively small chunk of the world’s third-largest island, Borneo, yet what a punch it packs: the treasure of turquoise-fringed desert islands with coral reefs swarming with marine biodiversity; trekkers' paradise Mt Kinabalu reaching 13435ft (4095m) into the clouds; and jungles pulsing with a menagerie of bug-eyed tarsiers, gibbons, pythons, clouded leopards and huge crocs. Around 55% of Sabah is forest, and protected areas such as the Maliau Basin and the Danum Valley Conservation Area are more accessible than ever.

Also known as the Gunung Mulu World Heritage Area, this park is one of the most majestic and thrilling nature destinations anywhere in Southeast Asia.

Sarawak makes access to Borneo’s natural wonders and cultural riches a breeze. From Kuching, the island’s most dynamic city, pristine rainforests – where you can spot orangutans, proboscis monkeys, crocodiles and the world’s largest flower, the rafflesia – can be visited on day trips, with time in the evening for a tasty meal and a drink by the waterfront. More adventurous travelers can take a ‘flying coffin’ riverboat up the 'Amazon of Borneo', the Batang Rejang, on their way east to hike from longhouse to longhouse in the cool environs of the Kelabit Highlands, or to the spectacular bat caves and extraordinary rock formations of Gunung Mulu National Park. For the best chance of seeing an orangutan in the wild, venture to the Batang Ai region.
