Cheapest way of getting around is using the dolmus minibuses. These are 11 seaters which travel the main road in Marmaris and Icmeler, the neighbouring resort. The fee is 1.50 TL anywhere in Marmaris and 2.50 TL between Icmeler and Marmaris. Marmaris dolmuses have a green band across them and orange for Icmeler. Other dolmus services serve Armutalan which is a suburb of Marmaris. The Armutalan dolmus has a blue band across them.
You can pick them up from the side of the road by hailing for them and they will stop wherever you want on the route.
Other buses are frequently available and compete with dolmus services. They are slightly cheaper and are council owned buses which are similar in concept but slightly larger than dolmus minibuses.
Taxis are also available on the meter or arranging prices up front but are very expensive prices are negotiable.
