Unless you are very comfortable on a scooter / motorcycle, are able to control them well on bumpy roads and don't have a nervous disposotion at all, stick to Taxis!
The car and truck drivers in Goa like to honk their horn, it seems just to see if it still works and like to drive close enough to people to have a conversation.
Taxi journeys get the adrenaline flowing but if you want a real thrill then hire a bike....it also seems helmets are optional!
The easiest and most efficient way to explore the surrounding area and maybe even Panaji and Old Goa is to rent a small motorbike. It's cheap and funny but, of course, can be dangerous so drive carefully (on the left!) and don't forget the helmet.
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.
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.
I have driven in America, and other countries, but I really never thought I would dare drive in India, after seeing all those videos of beeping and honking, pushing in and cars going in all directions.
After hiring a car of a local in Colva, we were off. We didnt know where we were going, only that we werent staying in Colva. We didnt give Colva much of a chance to be honest, but first impressions and all that.
After about half an hour, all of a sudden we were in Margoa, in the city centre, and I though, oh crap, straight into that crazy traffic you see on TV. But it was weird, it was as if we had a force field around us. As you move, other vehicles move with you and around you. You let people move, and they let you move.
Not like in the UK where if someone cut you up, you would curse at them or some might try to run you off the road if they thought you had cut them up. Oh no, this was so easy, you just move with it all, look ahead to where you want to go, and just gently merge and flow with the people and the traffic, it really is that easy.
Honestly, you will crap yourself for a few hours at first, but then will love it. And this is how you are really going to get to see Goa at it's best.
You'll see everyone whiz past on two-wheelers or scooters. Rent one for a week/duration of your stay but make sure to be safe, ride two to a scooter, and watch out for crazy driving! You'll need to watch the fuel tank and fill up before you return, so make note of the closest gas station since in most areas they are few and far between.
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.
