Lae is Papua New Guinea's second city, after the capital Port Moresby and its main economic hub as most of the production from the country's Highlands area is exported through the city, transported along the Highlands Highway. With no road connections between Port Moresby and much of the rest of the mainland, Lae's port is also the main way by which food from the Highlands (potatoes, sweet potatoes, cabbages, etc) reaches the capital. Coastal shipping from Lae also offers a cheaper transport option for those who cannot afford to fly to Port Moresby. Known as the "gateway to the Highlands", this does Lae a disservice as it has much to offer in its own right.
In the 1920s, Lae was the busiest airport in the world - it was there that aviators in the gold mining industry first proved that it was commercially feasible to ship cargo (and not just people) by air. Lae was the last known stop of aviator Amelia Earhart on her attempted around-the-world air journey in 1937. She did not reach Howland Island, her next planned refueling stop. During World War II, Lae was a major base for Japanese troops.
Lae's airport is at Nadzab, about 40km north of the city. This was a major US base towards the end of the war. It is served by:
- Air Niugini has several daily flights from the capital Port Moresby, as well as connecting Lae with several other centers in PNG. 
- Airlines PNG has flights from Goroka, Mt. Hagen and Port Moresby and a wide range of other towns in the country. It also has flights to Brisbane and Cairns in Queensland.
Lae can be reached by car from most cities in PNG's Highlands, via the Highlands Highway, and also from Madang on the north coast.
It is possible to get a berth on a coastal freighter from Port Moresby.
Take care when driving around Lae as, although the roads are improving, there are many pot holes.
It is advisible to leave a good space between yourself and the car in front of you so you can make a quick getaway if need be.
- Lae Botanic Gardens. Right in the heart of Lae city the gardens give a good appreciation of some of PNG's vegetation and attract a wide range of birds.
- Lae War Cemetery. Contains 2,818 Commonwealth burials of the Second World War, 444 of them unidentified.
- Morobe Show. This is held on the "weekend closest to the full moon in October". It is both an agricultural and industrial show as well as a cultural event that attracts many tourists, with emphasis on the culture of Morobe province. 
- The Rainforest Habitat. This is a self-funding display on 10 hectares at the Lae University of Technology and has a large collection of animals and birds, including a dozen of the 30 species of Bird of Paradise found in Papua New Guinea. The Habitat has around 80 Birds of Paradise, many on display in a 3,000 square metre rainforest enclosure.

- Lae Travellers Inn, Vee Street.
- Melanesian Hotel, 2nd Street (opposite the GPO). Check-in: Noon, check-out: 10.00.
It is inadvisable for a tourist to wander the streets of Lae alone, even in crowded shopping areas (crime). But for little or no money, a hotel guard may accompany a lone traveler for a short walk to go shopping or to the bank.
- Umboi Island. Once a week, a small ship leaves Lae for Umboi (stopping for cargo at Finschhafen). Many Papua New Guineans use the two small ships that make this tripe; few foreign tourists use the ships as they are spartan and used partially for cargo. Nevertheless, this is the only regular way to get to Umboi Island, the claimed home of the legendary "ropen", said to be a pterodactyl.
- Salamaua. Two hours south of Lae by boat, this was a popular weekend destination for the colonials in the pre-WWII era. They used to fly in to its small strip in their private planes. The area has some stunning beaches and good dives and quite a few Lae residents have weekend cottages there. Salamaua is just waiting for someone to build a hotel but for the time being you will either have to take a day trip or arrange for someone in the village to provide you with a bed.
- Bulolo and Wau. A few hours drive to these pre-War Gold Rush towns, now major centers for the timber industry and starting point for several important treks.
