There are quite a few things to do & see around Dalyan. Looking back through my diaries, there's:
. boat trips: to Turtle Beach; to the Thermal Springs at Sultaniye; to the market in Koycegiz; to the sulphur springs / mudbaths
. get a rowing boat over the river & walk to the ruins of Caunos
. dolmus to Marmaris for the day (what a contrast!)
. dolmuses to Fethiye (change at Ortaca)
. organised trips to Olu Deniz, Saklikent Gorge, jeep safari, rafting etc. etc.
And my fave: sitting in a riverside bar, watching the boats go by, sipping a vodka and tonic.
Ahhh.
