the one in hisaronu on monday is pretty much the same as the one in fetiyhe on a thursday.
the later is a lot bigger and a lot hotter,i found the best deals were had later in the day about an hour before the market shuts,so there is no need to rush there at the crack of dawn it will be less crowded as well.

hisaronu is on mondays and fethiye on tuesdays , fethiye is much bigger with lots more stalls but you can get plenty of stuff in either , i was there just last week ( got back yesterday)and it was fab i'm missing the place already

we love Gocek market on sundays .Get on a boat from fethiye takes about an hour spend about 2 hours in Gocek.Then back on the boat which stops a couple of times so you can swim in the sea.A lovely day and not to busy

thanks for the advice, im a bit confused now on which day fethiye market is...tuesday or thursday? what time do the markets end?

fethiye definately on tuesdays

fethiye market and hisaronu markets start packing up at about 4ish but there are still a few there at 5 just make sure you check the prices in the village or fethiye before you go as they are not always cheaper and with the village shops you can always return or change items
