Malaysia

Miri, Sarawak's second city, is a thriving town that is vibrant and modern. Thanks to the offshore oil, there are plenty of service industries and money sloshing around, so the eating is good, the broad avenues are brightly lit, and there’s plenty to do when it’s raining.

A skyline punctuated by minarets, Mogul-style domes and skyscrapers; colorful, food-stall-lined streets shaded by a leafy canopy of banyan trees – this is Kuala Lumpur.

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.

Whenever you enjoy a sunset off KK, the view tends to be improved by the five jungly humps of Manukan, Gaya, Sapi, Mamutik and Sulug islands. These swaths of sand, plus the reefs and cerulean waters in between them, make up Tunku Abdul Rahman National Park, covering a total area of just over 49 sq km (two-thirds of which is water). Only a short boat ride from KK, the islands are individually quite pretty, but in an effort to accommodate the ever-increasing tourist flow (especially large numbers of Chinese), barbecue stalls and restaurants now crowd the beaches. On weekends the islands can get very crowded, but on weekdays you can easily find some serenity. Snorkelling and diving are the islands' big draws.

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.

The main reason to come to Semporna is to get yourself over to the Semporna Archipelago, a short boat journey away. The dive companies are all conveniently located in the same area, and many have a dive center at the resorts on Mabul Island. If you've booked your dive and stay from KK already, you'll be picked up from the airport by your respective tour company and spirited straight to Semporna's port and onto your end destination, so there's no need to stay a night here.

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.

If you linger in Lahad Datu, and hook up with Bike & Tours, you can learn to cook the Borneo way, dive and snorkel the local reef and shipwreck without the Semporna/Mabul crowds, or go mountain biking up and down Mt Silam for scenic views of Darvel Bay. It's a far cry from the first glance of this little coastal town, which appears to have a lively produce market, dry-goods market, sun-scorched buildings and very little else. Travelers who breeze through en route to Tabin Wildlife Park and Danum Valley, arriving on early morning flights from KK and spirited away immediately, are missing out. Lahad Datu's location, roughly halfway between Semporna and Sungai Kinabatangan, makes it an ideal place to fly into from KK if you're looking to commune both with sea creatures and orangutans.

It's easy to see why the colonialist ruler Raja Brooke chose this spot for his capital. Hugging the curves of the languid Sungai Sarawak, Kuching was an ideal trading post between other Asian sea ports and Borneo's interior. It's still a gateway to both jungle and sea, and Kuching’s proximity to national parks makes it the ideal base for day trips to wild coastal and rainforest destinations.

You don't have to look too hard to find traces of old KL in Chinatown's shophouse-lined streets, which border the confluence of the Klang and Gombak rivers. This is where the city was born, reached its teenage years with the development of Chinatown and celebrated its late 20s with the establishment of the British colonial ensemble around Merdeka Square. The Malay fort that once topped the jungle-clad hill Bukit Nanas has long gone, replaced by one of the city's most recognisable landmarks, the Menara KL telecommunications tower.
