Otres Beach's quieter stretch and the remaining independent bars around Serendipity Beach offer a stripped-back version of the Cambodia coast nightlife before the major Chinese-resort development changed the city's character.
Sihanoukville changed significantly between 2016 and 2019, when a wave of Chinese investment transformed the city centre into a construction zone of casinos and high-rise hotels. The backpacker scene that made it famous largely relocated to Otres Beach, a quieter stretch of coastline about 3km south of the main town. Otres 1 and Otres 2 are the two sections: Otres 1 has the most bars and bungalow guesthouses; Otres 2 is calmer and has better-quality accommodation. Both have beach bar scenes that run from midday through midnight.
Serendipity Beach, the original backpacker base closer to the pier, still has a handful of independent bars and guesthouses that survived the transition, though the area is patchier than it was pre-2019. The islands off Sihanoukville — Koh Rong and Koh Rong Sanloem — have their own party scenes, particularly at Koh Tuch on Koh Rong, where beach bars run until the early hours most nights. Ferries from the pier take 45 minutes to Koh Rong and cost $8–$12 return.

Day-by-day breakdown
Otres 1 beach bars set out their chairs from midday. Mushroom Point and the various unnamed beach bars along the Otres 1 strip serve cocktails from $2.50 and beers from $1.50. Sunset from Otres Beach is directly over the Gulf of Thailand: reliably good from about 5:30pm. The beach crowd consolidates into the bar area as the light goes and the music volume rises.
Several Otres 1 bars run bonfire nights and themed events on different weeknights, advertised on handwritten signs along the beach. The parties are informal and mostly free entry. Connecting with other travellers at these is easy: the crowd is small, international, and mostly staying within 500 metres. Last food options are at the beach restaurants until about 11pm; after that, it is drinks only.
