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.
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.
Located besides the Celebes Sea, near to the Semporna Archipelago, Sabah's third city Tawau features some of the state's best seafood and is a more pleasant overnight alternative than Semporna. Bombed by the British colonialists in 1944 to force out the invading Japanese army, much of its historical architecture is gone, but beauty is not far away. Tawau is the gateway to the awesome Tawau Hills Park, the launch pad for spotting pygmy elephants on a private plantation. It's also the starting point for one of the most scenic long-distance drives in Sabah.
Emerald tea plantations unfurl across Malaysia's largest hill-station area. Temperatures in these 1300m to 1829m heights rarely top 30°C, inspiring convoys of weekenders to enjoy tea and strawberries in the restorative climate. Though technically in Pahang, the highlands are accessed from Perak.
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.
Dominating an archipelago of more than 100 islands and islets, Pulau Langkawi is synonymous with sandy shores, jungle-cloaked valleys and bargain shopping. Blonde beaches are the biggest draw, but this 478.5-sq-km island has been duty free since 1987, making low-cost kitchenware a close second.
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.
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.
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.
The Perhentian islands are well developed with resorts and yet still have refreshing, crystal-clear waters that are perfect for swimming, diving and snorkelling. There are hiking trails through jungles that are home to leaf monkeys, and numerous crescent beaches with shimmering white sand.
