Malaysia's stunning islands, cool highlands and breathtaking coastlines are blessed with gorgeous rainforests. Tucked away inside them are some of the finest tropical resorts in the world.

From a private mansion to VIP suites inside a gated research centre, here are the 10 best places to get away from it all:

Borneo Rainforest Lodge (BRL), Danum Valley, Sabah

Best feature: The Danum Valley canopy walkway

Borneo Rainforest Lodge, known as BRL, is arguably one of the most exclusive, luxurious and secluded resorts in Malaysia. Set deep within the Danum Valley Conservation Area, the nearest town is a 4 to 5 hour drive away.

The entire complex is built on wooden stilts with walkways raised above the ground to preserve the forest floor. The 30 chalets are perfectly positioned for privacy, yet everything is kept simple. That means no air conditioning, since BRL's cottages are cooled using an ingenious traditional method.

Best features: Pygmy elephants and an abundance of birds

As an exclusive resort within the Tabin Wildlife Reserve, Tabin Wildlife Resort places a strong emphasis on conservation and eco-friendly practices.

The beauty of this 30-year-old rainforest resort lies in the sheer number of endangered animals living in the reserve, making it one of the best places to watch Borneo's wildlife in its natural habitat.

Maliau Basin Conservation Area, Sabah

Best features: The Maliau sky bridge, the treetop walk and hiking.

Also known as Sabah's Lost World, the Maliau Basin Conservation Area covers 58,840 hectares (588.4 square kilometres). It has been declared a protected forest by the government and is one of the few relatively untouched wild areas left in the world.

The villa sits within the main research centre, where standard air-conditioned twin rooms and dormitories are also available.

Most facilities are open to visitors, but entry into the Maliau Basin requires prior permission from Yayasan Sabah or a tour operator offering packages to the basin.

Guests should also bear in mind that the Maliau Basin is a remote, isolated area with limited access, communications and security. It's ideal for any keen nature lover and outdoor enthusiast.

Best feature: Secluded, peaceful and beautiful nature walks (the list goes on).

If revered British wildlife broadcaster David Attenborough owned a luxury villa, it might well resemble the prestigious Datai Langkawi.

Nestled in dense rainforest in a secluded corner of Langkawi island, the Datai's 125 rooms and villas offer incredible views of the forest and the Andaman Sea.

Around for many years now, the repeatedly award-winning Datai is no longer a "best-kept secret," but it remains one of Malaysia's finest rainforest resorts, delivering world-class service and amenities.

The attention to detail at the Datai is unmatched. Guests won't regret splurging on the Villa Hutan Datai, a 550-square-metre retreat set apart from the main resort grounds, with separate pavilions for each of its three rooms plus dedicated dining and living areas.

Permai Rainforest Resort, Santubong, Sarawak

Best feature: Treehouses. Enough said.

The eco-resort Permai Rainforest Resort sits in pristine forest at the foot of the mystical Mount Santubong. Carefully designed to minimise its impact on the environment, it has been offering visitors a distinctive experience since the 1990s.

An hour's drive from Sarawak's capital, Kuching, Borneo Highlands Resort hides away in a mountain rainforest, 1,000 metres above sea level. It's well known among golfers thanks to the 18-hole Hornbill golf course. But there's plenty here for just about any visitor.
