Greenock is not a huge town, so it is fairly easy to get around the place on foot. However if you wish to wander around in the hills above the town to take advantage of the spectacular view of the mountains across the Clyde, then using a car to get to those places wouldn't be a bad idea. Taxi's are available all over greenock and are really cheap. The start fare is between £2 and £2.50. A trip from Greenock to Gourock will cost you less then £10.
The roads in Greenock are pretty easy to find your way around on, but you should definitely bring a streetmap. Also, watch out as the very centre of the town is governed by a quite awkward one-way system.
The locals are friendly despite what you may have heard and will gladly point you in the right direction.
