The route taxis have a pre determined route that they take. Either the beach road to the roundabout (middle of town) or the cliff road to the round about. A route taxi says that it it a route taxi on the side of the car and gives its rates, usually about 100j. No matter where you get in on his route thats what you pay. You can flag one down but usually they slow down and honk to see if you need a ride. Always ask to make sure they are charging you the 100j per person before you get in. The route taxi will stop on its way to pick up as many fares as he can fit in so you might be riding with a few other people. Sometimes if you ask they will take you somewhere else for more money but mostly they just run their route. So basically if you are staying on the beach and want to get to the cliffs, you hop in and go to the roundabout for 100j per person, get out and hop in another and it is another 100 j per person to the cliffs. Or if you are just going to the store you get out at the round about, do your stuff and catch another route taxi back.
