Phnom Penh is warm all year, and March to May is the best stretch for a rooftop swim. None of the 13 rooftop-pool hotels on our list sells day passes. Seven are guests-only and six don't publish who can swim.
Our first pick is The Peninsula Phnom Penh, an infinity pool that faces the Tonle Sap River and shares its roof with a sky bar. Its floor, hours and non-guest access aren't published, so ask before you book. Hotel Emion is the easier one to plan around: an 18th-floor pool open 6:00 to 22:00.

Plan around three holidays. Pchum Ben (about 24 Sep to 8 Oct 2029) and Khmer New Year (mid-April 2029) are listed as closure periods, and many shops and services close. The Water Festival, Bon Om Touk, is a book-ahead date at about 20 to 22 Nov 2029. These are lunar dates and may be a day off.

Where to stay: Phnom Penh's rooftop pools by area
Daun Penh (Khan Doun Penh)
Home to the Royal Palace, Wat Phnom and the National Museum, this is the most central area in the city. Central Market, a spot for street food and shopping, is also here. Hotel Emion, Chaiya Palace, Aquarius, Penh House, Wyndham Grand, Harmony and Phnom Penh 51 are all in Khan Doun Penh.
Cheaper ways to swim in Phnom Penh
Garden City Water Park is the cheaper way to swim in Phnom Penh, with an adult day pass at $12.50. It is a water park, not a rooftop, but it is open to anyone who pays.
Garden City Water Park: $12.50. A water park option in Phnom Penh; the source gives $12.50 as the adult day pass price.
Hotels you might expect here, and why they're not
Two hotels people expect here aren't on the list, because no source puts their pools on the roof or a top-floor terrace.
The Balé Phnom Penh by LifestyleRetreats. The hotel's own site describes its main pool as a riverside pool on the Mekong. No source places it on the roof or a top-floor terrace, and no second source confirms a pool at all.
Pavilion Hotel. Hotel sources describe two garden-set swimming pools and private plunge pools in some rooms. None is stated to be on the roof or a top-floor terrace.
Phnom Penh rooftop pools: questions people ask
Can you swim at Phnom Penh rooftop pools without staying?
No hotel on our list sells day passes. Seven are guests-only: Luxcity, Anik Palace, Patio, Wyndham Grand, Katari, Harmony and Phnom Penh 51. The other six don't publish access rules, so ask The Peninsula, Hotel Emion, Chaiya Palace, Aquarius, The Skye or Penh House directly.
Are any Phnom Penh rooftop pools heated or open in winter?
Yes, one: Wyndham Grand is described as a heated outdoor rooftop sky pool. The other hotels don't publish heating. Winter is warm anyway, with average highs of 30.8°C in December and 31.6°C in January.
Which hotel has the highest rooftop pool in Phnom Penh?
Hotel Emion, with a pool on the 18th floor. Three hotels publish a floor: Emion (18th), Chaiya Palace (16th) and Patio Hotel (8th). The rest don't say.
Are Phnom Penh rooftop pools family-friendly or adults-only?
The hotels on our list don't publish an age policy, so check with the hotel first if you're bringing children. Most are stay-only pools, and several sit beside a sky bar, including Patio, Chaiya Palace and Harmony.
How can I swim in Phnom Penh for the least money?
The number to know is $12.50, the adult day pass at Garden City Water Park. None of the rooftop hotels on our list sells a day pass. Anik Palace is the one to try if you book a spa treatment, since its spa package includes free pool access.
Which Phnom Penh rooftop pool should I book first?
The Peninsula Phnom Penh is our first pick, for its infinity pool facing the Tonle Sap River. Its floor, hours and non-guest access aren't published. If you want published details, choose Hotel Emion, with an 18th-floor pool open 6:00 to 22:00.
