Thane (also called Thana) is a city in Konkan, Maharashtra. It is the headquarters of Thane district. Its biggest claim to fame is that the first railway line laid in India was from Bombay VT to Thane station.
Thane city, for all practical purposes is a suburb of Mumbai. But it is worth mentioning for the 30 lakes located within and around the city, earning it the sobriquet of Lake City. Apart from being a source of water for Thane and its larger neighbour, the lakes are also tourist attractions. The areas surrounding the city are beautiful. The scenic locales, old forts, boat rides and resorts make Thane a great getaway from Mumbai.
The nearest airport is the Chhatrapati Shivaji International Airport , Mumbai. Once you get off, you will need to take a taxi or hire a car. The distance to Thane is about 36 kilometers (22 miles), the drive can take between 45 to 75 minutes depending on the traffic.
Mumbai's taxis are allowed into Thane. The prepaid taxi service available at the airport is the recommended hassle-free way of getting to Thane. The fare you pay at the counter includes the toll you need to pay when you leave Mumbai.
The best way to get to Thane from Mumbai using public transport is to take the local train service. If you are coming from the airport, take an auto-rickshaw to Andheri station which is served by the Western Railway and buy a ticket to Thane. You need to take a southbound train towards Churchgate, get off at Dadar (which is the interchange point), get on the Central Railway Line and then take a northbound train to Thane. This method is recommended only if you are adventurous at heart and are not carrying any luggage.
Thane is also well served by long distance trains, many of which stop at Thane station en route Mumbai.
Two main roads enter the city from Mumbai. The older one is the Lal Bahadur Shastri Marg (commonly abbreviated as LBS Marg) and Eastern Express highway. Both of them are toll roads - the toll gate (called naaka) for the former is called Teen Hath Naka while that for the latter is called Check Naka. The toll at both the naakas is 25 rupees one way which is somewhat unfair because there is a huge difference in the condition of the two roads.
LBS marg is invariably congested, encroached upon and potholed. It goes through the heart of Mumbai's Mumbai/Central Suburbs. The Eastern Express highway is wide, well-maintained and smooth. It goes through an uninhabited area where development is prohibited. Use this road to get in, even though the distance will be slightly more. The roads intersect at Marathon chowk ("Marathon square", because that's where the Thane Mayor's Marathon starts from.). LBS marg then goes right through the city, while the Eastern Express highway skirts it and turns into NH - 3 highway to Nashik and Agra.
There are very few BEST buses that go right up to Marathon Chowk (It is known as "Teen Haath naka")- 30 Ltd. 399 and 496 Ltd. Check the BEST site  for more. Once you get off, catch a TMT bus or auto-rickshaw.From this spot Thane railway station is hardly 10-12 min walk if you go by following Gokhale Road , & auto should not cost more than 10-15 Rupees.
Most private buses from various parts of the country will stop in Thane. Maharashtra State Road Transport Corporation (MSRTC) buses will ply from various parts of Maharashtra to Thane.
Note that auto-rickshaws from Mumbai cannot enter Thane city limits. You will have to change over to another one at the toll-gate.
The area around Masunda Lake, called Talao pali ("talao" meaning lake) is the heart of the city. Most of the important landmarks are located here.
Ram Maruti Road, Gokhale Road and LBS Marg are the important roads to criss-cross this area. The other important road is Ghodbunder Road which connects the eastern and western halves of the city and joins the Eastern Express Highway.
Thane Municipal Transport (TMT) runs a bus service through the city.
The most common way to get around in Thane is to hire an auto rickshaw. Payment is by meter. The amount to pay, however, is not the amount shown by the meter, but scaled up by a factor which changes whenever there is a rate adjustment. Check the tariff card for the right fare.
If you are on a day trip from Mumbai, one of the options is to catch a taxi in Mumbai and use it to go around Thane city. You cannot flag down taxis in the city as you won't find any, but you can certainly hire one.
The old shopping areas are the ever busy Ram Maruti Road and the Naupada road towards Thane Station. There you will find shops on the roadside. New malls are coming up on Ghodbunder Road and the Eastern Express highway. Prominent among them are:
In addition, there is a McDonalds close to the railway station, another McDonalds at the Lake City Mall, a Pizza hut at Wonder mall (see Buy) and a Dominos near Hiranandani Estate.
Some of the restaurants listed under Eat have bars where you can have a drink, but Thane is not a place known for its nightlife. The lower end bars tend to be sleazy, so you need to be careful.
Cafe Coffee Day  has two outlets here.
There are many lodges near the railway station, but there is a lack of decent hotels.
