Beach and water
Icmeler beach is the more family-friendly of the two: a wide imported-sand crescent that has held the Blue Flag every summer since 2009, water that shelves gently for fifty metres, and lifeguards in summer. Marmaris beach is longer but more urban; the central section is paved seafront fronting hotels rather than a continuous sand strip. For under-tens, Icmeler is the obvious pick.
