Various ways of travelling too and from Ahmedabad in India i.e. flying there, using Indian Railways or by car.
Flights to Ahmedabad.
The fastest way is obviously by air - there are several flights each day out of Mumbai and it's also worth noting that at time of writing there is a direct daily flight to Goa on Spicejet. (Check this for changes of course).
Other commercial domestic airlines which utilise the airport are Air India, IndiGo Goair and Jet Airways - offering direct flights to destinations such as Delhi, Mumbai, Pune, Chennai, Kolkata, Jaipur, Bangalore, Bhopal and Hyderabad. There are also several international airlines using the airport - Singapore Airlines, Emirates, Etihad, Turkish Airlines and Qatar Airways.

Ahmedabad's airport is very spacey, modern looking and clean and has the impressive name of Sardar Vallabhbhai Patel International Airport
- it is situated around 8kms from the city centre.
Alternatives: Although flights between cities in India are still relatively cheap - perhaps surprisingly it can be even cheaper to hire a car and driver
if there are two or more of you travelling. Considering that the roads are being improved all the time now in many parts of India this can be a good alternative and not make much difference in travel time if you are going maybe 300 or so kms. Also of course with a car and driver you can perhaps pick out a few places to stop and look around on the way.
Indian Railways: Ahmedabad
actually has half a dozen railway stations but the main station is within the walled city to the east of the river at Kalupur - and is therefore known generally as Kalupur station. There are trains available to quite a few of India's cities - some of the trains even go relatively quickly! - amongst the cities served are Bangalore, Chennai, Delhi, Hyderabad, Indore, Kolkata and of course
Mumbai. Generally speaking travelling on Indian Railways remains quite a slow process but it certainly is a cheap way of getting somewhere. The more popular destinations are often heavily booked and the
ticket booking process - if done online - is a little involved to start with as you have to set up a user id.

After a day of sightseeing and perhaps before settling down for an evening meal etc. taking an auto-rickshaw out to Kanaria Lake can be a good idea. The lake is one of the largest in Ahmedabad and it's more or less due east of Sardar Bridge - the main entrance gate to Kankaria Lake is located at the end of Kankaria Road.
The circular Lake was constructed during the reign of Sultan
Qutbuddin during the 15th century - a quite wide walkway (2.3km long) goes right round the lake and there are various facilities such as food and drink stalls at regular intervals. There are rides available on a miniature railway plus paddle and power-boat rides and other children's activities and so on. This makes the lake extremely popular for Ahmedabad's residents who turn up in the early evening in huge numbers to take a stroll round and enjoy the activities.
By
1700hrs the queues for entrance tickets can be enormous - women have one ticket booth and men a different booth although tickets can be brought in one go for both sexes (tickets are 10rs). As dusk falls the entire edge of the lake is lit up with coloured lights - certainly worth the effort to go and see it all.
