The beach at Misano Adriatico is the typical Adriatic setup: fine sand, shallow water that warms up quickly in summer, and rows of private lido operators renting out sunbeds and umbrellas. The water is calm and safe for children.
Most of the beach is managed by private concessions (stabilimenti balneari), so you will pay for a spot. A small stretch of free beach (spiaggia libera) exists but fills up fast in August. The water gets crowded during peak summer weeks; May, June, and September offer a more relaxed experience with the sea still warm enough to swim.
The Porto Verde area at the southern end of town has a somewhat different character — the marina rather than the open beach is the focus there, and it tends to attract a slightly older crowd.
