An evening at Arkadia is a must when in Odesa and this is definitely the city's best place to see and be seen. Here you can play old-school arcade games, dress up like a tsar or tsarina for a photo op, or hang out in a variety of cafes, bars and clubs.
The central part of the beach is almost entirely occupied by beach clubs, which have pools and double as nightclubs after sunset. They usually charge 50uah to 100uah for admission and a sunbed, but a lot more to rent a towel.
Arkadia is easy to reach: take tram 5 from the tram stop near the train station, in front of the McDonald's on vul Panteleymonivska, to the end of the line via the lovely tree-lined bul Frantsuzsky, where the crème de la crème of Odesa's aristocracy lived in tsarist times. Enjoy the views of the old mansions and sanatoriums along the way. Public transport to Arkadia gets extremely crowded in summer, so consider taking a taxi (around 40uah).
The crowds begin to thin out and the water gets cleaner as you head south to the area known as Bolshoy Fontan; take tram 18 from the tram stop near the train station.
