Start around 11:00 at Fethiye Fish Market, where the central market hall is at its liveliest and the seafood selection is usually best. Walk around the counters, choose fish or prawns, then take your purchase to one of the surrounding restaurants to have it grilled with salad and bread. Allow about 1½ hours and roughly ₺600–1,200 per person, depending on your seafood choice and drinks. It is an easy walk from most central hotels; taxis are inexpensive if you are staying farther out, though parking near the market is limited.
After lunch, wander through Paspatur, the old town’s cool, shaded lanes, looking out for Ottoman-era wooden details, small craft shops, spice stalls, and traditional lokantas. Keep this unhurried—this is the best part of the day for browsing rather than following a strict route. From Paspatur, Fethiye Museum is a short walk toward the town centre. Spend about an hour with its Lycian and Roman sculptures, inscriptions, and coins; opening hours can change seasonally, so check locally, and expect a modest admission fee, generally around ₺100–200. The museum is most comfortable before the intense afternoon heat.
Take a taxi or walk uphill from the museum to the Amyntas Rock Tombs—the climb takes roughly 15–20 minutes on foot, but a taxi is worthwhile in August. Allow an hour, wear proper shoes, and carry water: the uneven steps and exposed stone become very hot. The tombs are usually visited until around sunset, with an inexpensive entrance fee, and the elevated view over Fethiye is particularly good in the late afternoon. Afterwards, return downhill toward Fethiye Marina—about 10 minutes by taxi or 20–25 minutes on foot—for a relaxed waterfront stroll and sunset over the bay. Choose a waterside drink or a simple dinner nearby, but book ahead if you want a table with a direct harbor view; August evenings are busy.
