Aquarium Near Me in Mandai: River Wonders and Its Amazon Manatees

River Wonders at 80 Mandai Lake Road is Singapore's river-themed wildlife park, opened as River Safari in 2013. Its Amazon Flooded Forest tank holds manatees, arapaima and giant river otters, and adult non-resident tickets are S$45.

River Wonders opens daily from 9am to 6pm at 80 Mandai Lake Road, Singapore 729826, with last entry at 5pm and non-resident tickets at S$45 for adults and S$33 for children aged 3 to 12. For anyone in the north of the island typing aquarium near me, this is the freshwater answer: Mandai bills its Amazon Flooded Forest as the world's largest freshwater aquarium, a tunnel of manatees, arapaima and giant river otters, inside a 12-hectare park of river habitats.

Plan a Mandai River Day

From River Safari in 2013 to River Wonders

The park soft-opened as River Safari on 3 April 2013, built between Singapore Zoo and Night Safari as Asia's first river-themed wildlife park. Australasian Leisure Management reported the attraction cost US$160 million and that the Amazon Flooded Forest viewing window measured 22 by 4 metres, holding 2,000 cubic metres of water. Back then an adult ticket cost S$35, and the boat rides were not ready yet. The park was officially opened on 28 February 2014.

On 13 October 2021 the Mandai Wildlife Group renamed River Safari as River Wonders, in the same rebrand that gave the relocating Jurong Bird Park its new name, Bird Paradise. Today the official site counts over 11,000 land and aquatic animals from 260 species, calling it one of the world's largest collections of freshwater vertebrates. The galleries still keep the river-by-river layout, with zones named for the Congo, Nile, Ganges, Mekong, Yangtze and Australia's Mary River alongside the Amazon.

Inside the Amazon Flooded Forest Tunnel

The Amazon Flooded Forest recreates the season when forests along the Amazon sit under more than 10 metres of water, and the animals feed among drowned trunks. Manatees are the stars. Eva, born in 1991, weighs about 1,200kg and has mothered eight calves; Pedro, born in 1979, is the oldest male, recognisable by his long, lanky frame. Canola, born in 2014, was hand-raised by aquarists on puppy formula and goat milk laced with canola oil.

The same habitat holds arapaima, black-finned pacu, discus, altum angelfish and an electric eel capable of 800 volts. Mandai says its giant river otters were the first displayed in Asia, and its otter breeding, coordinated under the European EAZA programme, was another Asian first. Look for Chico and Carla or their younger siblings through the tunnel glass, then climb to the upper sandbank, where the family naps through the afternoon. Listen closely. Giant otters use nine different calls.

The 3:30pm Amazon Flooded Forest Keeper Guided Trail starts at the discus tank and ends at the otter exhibit on the upper level, covering the manatees, otters and electric eel. Manatees here graze on Chinese cabbage, banana leaves and elephant grass, eating up to 7% of their body weight daily. The 12:15pm Amazonia trail, by contrast, is a lunchtime feeding of silver arowana, white-faced saki and Azara's agouti.

Mekong Giants, Gharials and the Panda Biodome

The Mekong River exhibit is a tank the size of four double-decker buses, holding Mekong giant catfish that grow to 3.2 metres, giant freshwater stingrays that can reach 600kg, and Siamese carp. The 2:15pm Rivers of the World trail runs from the elephantnose fish near the Congo River exhibit to the catfish tank. The Ganges zone has the Indian gharial with its narrow, tooth-lined snout, and River Gems shows tetras, rasboras and rainbowfish.

The Pavilion Capital Giant Panda Forest, open from 9:30am, is a 1,500-square-metre climate-controlled biodome kept at 50 to 60 percent humidity for Kai Kai and Jia Jia, the parents of Le Le, Singapore's first panda cub. Through the kitchen windows you can watch keepers prepare bamboo, served in 5kg batches every two to three hours. Red panda Karma lives here, while Yaffa, born in 2015 and newly arrived from Taipei Zoo, lives in the Yangtze River zone.

S$45 Tickets, the S$5 Boat and Booked Show Seats

Non-residents pay S$45 per adult and S$33 per child. Children under 3 enter free with an adult. Residents with a free WildPass pay S$35 on weekdays and S$40 on weekends for adults, and seniors over 60 pay S$25. The Amazon River Quest boat costs S$5 per rider, last ride at 5:30pm, with a 1.06m minimum height and a child-swap system. Its route passes a Brazilian tapir, a giant anteater and a jaguar inside a dark cave.

Once Upon a River runs at 11:30am, 2:30pm and 4:30pm at Boat Plaza, and you cannot just queue: seats must be booked online from two hours before showtime, toddlers count as a headcount, and you must be there 15 minutes early or your seats are released. Flash photography is banned, since it startles the animals. Strollers rent for S$15 and wagons for two children for S$18, and Entrance Plaza lockers cost S$12 for the first three hours.

Who Comes, and When to Skip the Boat

The facilities show who the park is built for: wagons for two children, nursing rooms in four zones, and a Kids' Learning Adventure Guide. On 17 and 18 October 2026 the park opens at 8am for Quiet Mornings, an early hour for guests sensitive to crowds and loud sounds, with an activity booth running until 1pm. One visitor quoted on Mandai's site summed up the appeal: it feels like an outdoor aquarium, with pandas and a simple yet interesting ride.

One honest call: do not buy the S$5 Amazon River Quest on a stormy afternoon. Mandai suspends the boat when weather affects safety, and ride tickets are not replaced if that happens. Its animals also hide in vegetation, so a short dry-weather ride is the better bet. The plan B is the rest of the park, which is mostly under shelter, though staff ask guests to head indoors when lightning starts.

M2 Khatib Bus or Bus 138 to Mandai Lake Road

River Wonders sits at Mandai Wildlife EAST, the same entrance complex as Singapore Zoo and Night Safari. The quickest public route is the M2 Khatib Bus from Exit A of Khatib MRT on the North-South Line, a roughly 20-minute ride for S$2.50 by EZ-Link or contactless card, with buses every 15 minutes from 8:30am. Children under 7 ride free. Bus 138 from Ang Mo Kio or Springleaf, and 927 from Choa Chu Kang, stop at Singapore Zoo (48131).

Tree Frog's Hangout and the Mandai Boardwalk

Just left of the River Wonders entrance, the Tree Frog's Hangout gate leads onto the free 3.3km Mandai Boardwalk, open 7am to 7pm, which skirts the park and Singapore Zoo along Upper Seletar Reservoir. Stop at Iora's Nest, a lookout over the reservoir and grasslands, or Eagle's Perch for wider water views, and watch for white-bellied sea eagles, Malayan water monitors and wild smooth-coated otters, a neat contrast with the giant otters indoors.
