Lautoka is in Fiji.
Bus or taxi from Nadi or Nadi Airport. There are a lot of companies which provide a car rental service. It takes approximately 1 hour to get to Lautoka from Nadi by car.
Lautoka has a robust public bus transport network operated by private companies and the service is run on scheduled timetables from the central bus station.
Local buses are cheap and reliable. You'll probably be the only non Fijian person on the bus but don't let this deter you. It can get very crowded: men usually take vacant seats next to other men, and same for women.
Yellow local buses are FJD $1 (some pay when you get on, others pay when you get off!). Air conditioned coaches are FJD $2.
There is also taxi and carrier service available which is useful for those in a hurry. Although costs are based on stages travelled and set by the government fares should be agreed to before travel to avoid later disputes.
Lautoka feels very far from the ultra-touristy island life. If you're sick of everyone yelling 'Bula!' and want to observe some locals and eat some cheap Indian food, check out this town about 20km from Nadi. It has a significant industrial and administrative element - there is a large sugar cane factory just south of town and lots of banks. For an unforgettable experience, visit the Hunters nightclub: fights at 9pm, grotesque graffiti, good music.
The Hare Krishna temple is a friendly place. If you happen to be there on a Sunday, then pop in and they may invite you to stay for lunch.
Lautoka's Sugar Mill is also a great place to see. People there are very friendly and will help you to get to the main gate in case you've never been there before. There are 4 or 5 gates and it is necessary to get to the main one in order to be let in. It's necessary to make an appointment before your visit and take proper shoes (boots). The Sugar Mill trip does not cost anything and is really worth seeing.
The Botanical gardens have a large variety of tropical plants most of them labelled with the botanic and common names. If you visit around midday on a working day you may see the horticulturist Shri on site who has a wealth of information on the plants. The park opposite the gardens is a favourite playground for children, and there are toilet facilities.
Note: Chinese in Fiji is actually more spicy than Thai in Fiji.
