Not too sure about the Segways etc but the little train would have been perfect for us during our holiday in Koca Calis. One week before our holiday our daughter dislocated her knee so walking into Calis, like we usually enjoy doing, was out of the question. We relied on taxis because the dolmus runs straight to Fethiye from where we were staying but the train would have been a fun way of getting around! Having said that, we spent more evenings at the beach restaurants in Koca Calis which we loved.
