there is no bank in katelios. That is not a problem though as the car rental changes travellers cheques, and the mini market down the road give you cash back with well know cards
as you walk down and on to your right follow the rubble road past the taverners you will pass a small fresh water pond with ducks, geese and fresh water fish. Carry on down the road there is a beach there at first glims it does not look much but i thought it was very nice. you can also hire a boat for the day to get to beaches that are off limets to a car.
I'M SORRY TO SAY THIS BUT NO !!! THERE ARE BUSES ON THE ISLAND BUT NO TIME TABLES.
I USED A VISA CARD WITH NO PROBLEM. WE HAD A GREAT TIME THERE SOME OF THE RESTAURANTS DID EXCEPT VISA BUT A LOT PROFFERED CASH AND I DO MEAN A LOT
as there is no bank in this area i used a visa card to get cash back at one of the two shops
i do hope you have a great time there
