Changi Airport consists of four passenger terminals and Jewel, a nature-themed entertainment and retail complex surrounded by and linked to one of the passenger terminals.
In March, Changi was named the best airport in the world for the eighth consecutive year by airport evaluation group Skytrax.
The 40-meter-high Vortex HSBC Rain waterfall (pictured), the tallest indoor waterfall in the world, is in the Jewel area.
The location is open to visitors for free. Surrounding the waterfall is the Shiseido forest, with 2,500 tall trees and 100,000 shrubs of all kinds that help regulate the air.
The skytrain connects Terminal 2 and 3 and takes a ride past the waterfall.
In the evening, the waterfall will change color, combining music to create a beautiful light and sound show.
Tourists pose for photos on Canopy Bridge, a 50-meter long glass paneled bridge, suspended 23 meters above the airport.
Foreigners can buy sightseeing tickets at S$13.90 (US$10.40) for adults and S$11.90 for children.
This picture was taken at Hedge Maze on the top floor of Changi Airport at Canopy Park on Level 5.
It is known as Singapore's largest hedge maze, with hedge walls standing at 1.8 m high. An elevated watchtower gives visitors a panoramic view of the maze.
Admission tickets are the same price as at Canopy Bridge.
One of the impressive highlights at Jewel shopping center is Changi Experience Studio that uses technology to tell stories, combine interactive games, image projections, sound and light so that visitors do not feel bored when visiting.

Changi Airport has seven themed gardens such as sunflower garden, cactus garden, crystal garden.
Pictured is the butterfly garden that is home to over 1,000 butterflies. Located in Terminal 3, it is the first of its kind in an airport and features a 6 m tall grotto waterfall.
At Terminal 3, passengers can visit the Candy Snow House area on the first floor to experience the minus 10 degrees Celsius cold in a tropical airport.
Inside the snow house are miniatures such as snowmen, ice slides, reindeer sleighs and bowling and skiing games. Entry tickets cost S$18 for a one-hour experience.
Before entering the snow house, visitors are equipped with life jackets and thermal gloves.
From early November, Changi Airport fully reopened Terminal 2 following a massive 3.5-year expansion project.
In the transit area, a garden dubbed Dreamscape features 20,000 plants selected from about 100 species from ferns to shrubs.
The garden has a transparent platform over a fishpond, accompanied by the sounds of nature in the form of recordings of local wildlife taken from different parts of Singapore, including PulauUbin.
The fishpond is home to cichlids and aquatic plants.
A 14-meter-high digital waterfall is also the highlight at Terminal 2.
Surrounded by a vertical garden, “The Wonderfall” is located in the departure hall and cascades over megalithic boulders.
This virtual waterfall is made up of 892 pieces of flat and curved tiles, along with an LED screen showing an endless flowing waterfall with constantly changing colors.
