Visiting Goa : Some non-trivial information

I assume you have visited few sites already before coming here so I am putting information which I think is non-trivial and not available on other places ,
but is quite useful ,specially if you are having a packed schedule and want to save as much money as possible.

Goa is actually a state and not a city. Its got two districts, North Goa and South Goa. River Mandovi does the bifurcation.
South goa is more for family and leisure kind of place like temples, churches, ancient and historical buildings(Old Goa), museums etc though its got beaches also like Colva ( Kind of beaches in Goa ). Panjim which is capital of Goa is also part of south Goa though its almost at boundary of it.Major casinos of Goa are in Panjim. Main city of south goa is Madgaon which has got railway and bus
stations. If you are reaching Goa by train or bus, mostly you will land to Madgaon .
North Goa is more youth and happenig with beaches like Baga, Chandolim , Calangatge( queen of beaches ). Most of the night clubs are near Baga beach.

Goa Bus Services:
--------------------------
Taxis in Goa are NOT cheap, and in peak season they are quite costly. I was there for xMas and from Colva beach (south goa) if I had to go to Baga beach(north goa), they would charge me minimum 1600 to 1800 Rs. Return fare would be 2000 to 2500 Rs.
Because its ~60 KMs. Easier approach is to take city buses. Few facts about them
1. they operate till 8 pm only.
2. From south goa , you have to go to Madgaon bus Station to catch bus.
3. From north goa , you can catch bus on major roads, near beaches. Ask any shopkeeper/police man there and they would tell you. There are NO dedicated bus stops as such. Just raise your hand and they would stop the bus.
4. There are NO buses directly from North to South goa or Vice versa. You have to go to Panjim and change there.
5. If you are in South Goa , go to Madgaon by Auto/Taxi or Local Bus , go to counter which says NonStop buses to Panjim. Take a ticket and reach Panjim in 30-40 mins .From Panjim , take bus going to Calangate beach , chandolim beach would come on the way. Last stop is Calangate and Baga beach.
6. If you are in North Goa , catch a Bus going to Panjim from the road, reach Panjim bus stop in 20 mins time. From there go counter which says non-stop service tp Madgaon , grab a ticket ( ~22 Rs) and reach Madgaon. From there , ask for local buses at enquiry to go to place of interest.

Buses are cheap and quite fast.
