places best for stay ("unbelivable pools")

MARINA BAY, SINGAPORE:-

This massive infinity pool in Singapore sits atop the 57-story Marina Bay Sands hotel, with sweeping views of the city-state’s skyline. The 490-foot pool is cantilevered over the hotel’s north tower. Only hotel guests are allowed to swim and sip their cocktails by the pool, but others can purchase a ticket to the observation deck to soak up the view.

SELJAVALLALAUG, ICELAND:-

In southern Iceland, this 82-foot pool built into the side of a mountain goes largely unnoticed by travelers. A half hour rocky hike through a river valley is necessary to reach the outdoor geothermal pool, Iceland’s oldest, built in 1923 to teach locals how to swim. Now it’s operated by volunteers and open to the public. But so few visit, you may have a wild swim (watch the algae), with its views of snowy mountains, all to yourself.

FREGATE ISLAND, SEYCHELLES

:-

 Each of the 16 villas on Fregate Island in the Seychelles has its own infinity pool, hot tub, and private veranda. There’s also a shared freshwater pool. After you dry off, you can hop into the Indian Ocean for snorkeling and scuba diving, and maybe catch sight of a dolphin or whale shark.

KOH SAMUI, THAILAND

:-

The Library hotel's swimming pool certainly makes a bold statement with a mosaic of deep red tiles contrasting against the white sandy beach of Chaweng. The hotel’s signature library offers a collection of more than 1,300 books to read poolside.

BUDAPEST, HUNGARY

:-

Effervescent mineral baths fill this thermal pool, opened in 1918 as part of the Gellert Hotel in Hungary’s capital. But bathers have sought out the healing waters that fill the spa on and off since the 13th century. The pool water naturally reaches up to 104 degrees Fahrenheit. Eye-catching architecture of the indoor pool includes Art Nouveau mosaics, marble sculptures, and columns under a stained glass skylight.

BALI, INDONESIA

:-

Guests staying at the Hanging Gardens Bali hotel in the Balinese jungle can take in gorgeous sunsets and possibly spot a monkey in the trees as they take a dip. The two-tiered infinity pool seemingly hangs in the treetops over the lush rainforest and the Ayung River below

SWEIMEH, JORDAN 

:-

It only rains about 15 days a year at the Kempinski Hotel Ishtar, about an hour’s drive from Amman, but if you want to get wet there are plenty of options. The resort is located on the banks of the Dead Sea, the lowest point you can stand on Earth, where the water is 10 times saltier than the ocean. You can slather on dark mud and float in the mineral rich waters of the salt lake. Then you can check out nine freshwater outdoor pools, lined with palm trees and a pool bar.
