Find yourself a good taxi driver at the start. On your first day ask a few drivers how much they would charge to take you somewhere or to hire for the day adns ee who gives you the best price. Then keep them for the holiday. Book your next trip each time you finish the last because then you are not having to go through the whole price thing every time. Also agree the price before you set off on a trip then you know where you are and there no surprises.
Use your taxi driver for excursions. the tour operators charge a fortune and your taxi drive will be able to take you for a fraction of the price. Also if you get a good one he will even do some haggling for you and ward of the beggars.
Don't hire a scooter unless you are extrememely brave. I did see some tourists on them but I have never seen roads so crazy and they leave only an inch gap when passing if necessary, if that! My partner is very experienced at driving a scooter in the craziest of places but even he was put off.
Tuc tuc's are a cheaper form of transport. The motorised rickshaws but are only good for short journeys as they are very bumpy and not too comfortable.
A cheaper means of short travel than taking a taxi is to use a three-wheeler tuk-tuk which is an interesting experience.
They zoom around even faster than the taxis and most of the tuk-tuk drivers have one hand on the outside horn to blast at everyone who is remotely around the road in front of them.
Many people don't use buses when they holiday abroad, especially in areas like India, Africa and the like.
Not using the local bus ca be missing out on a great part of the general holiday experience. Generally they are clean and well operated "No Standing - No Spitting" and by far the cheapest way of travelling around.
Goan Taxis and Taxi Drivers are generally really friendly and great value. Make sure you agree a price before you travel and if you are happy with the journey - book another journey or leave a rounded up tip. Sometimes the taxis may ask you if you want to visit a shop. If you arent in a rush - you could do this as the driver can receive tokens for prizes. Generally though - we found these shops to be a complete rip off compared to the markets and the shops around the beaches.
We also took a return taxi to Old Goa, Arpoora and Anjuna - which wasnt too expensive - and the drivers Angelo and Jack looked after us well.
These little motorised scooters buzz around Goa like busy bee's. Definately an experience worth doing but I'd suggest only for local journeys.
The jeeps in Molem are the only vehicles allowed to go to the falls. They can - and do - charge what they like. Save money by waiting for others to join you to share the cost.
the road to south goa passes besides the mandovi river.
this beautiful stretch of road is seen just after you descend down from the bridge over mandovi and turn left towards south goa.
There are several motorcycle rickshaws (Tuk-Tuk) in Goa. And it is easy and cheap to travel around with them. You pay 50-100 rupies for a trip.
