Monkey Valley - Now Open!

Adventure into Monkey Valley at ZSL London Zoo

Our colobus monkeys have leapt into their soaring new home!

ZSL London Zoo’s landmark Monkey Valley is now open to visitors, with the iconic Snowdon Aviary newly transformed into a walk-through exhibit that soars an incredible 80ft above the London skyline. 

Transporting visitors to the lush mountainous forest of Central Africa, against the backdrop of a 30ft waterfall and peaceful lagoon, be one of the first to step into Monkey Valley and experience our troop of gravity-defying, 'high-flying' colobus monkeys leaping, lounging, swinging, and snoozing, in their new tree-top inspired habitat.


The walk-through may be closed at certain times throughout the day for a limited period of time to allow our monkeys to rest, however visitors can still explore the surrounding area or come back later to experience the walk-through. Monkey Valley is currently open to walkthrough tours from 10am - 12pm and 1.30pm - 4pm (last entry at 3.55pm). Opening times are subject to change at short notice and we apologise for any disappointment caused. 

Soaring 80ft above the Primrose Hill skyline - the height of six London double-decker buses - the new walkthrough in Monkey Valley features a range of monkey upgrades, including multi-level sunny and shaded basking spots for the ten troop members to lounge in, more than 800 metres of rope to swing on, 1,347 new plants and trees to leap amongst and a 30ft waterfall.

Visitors can walk alongside these incredible monkeys before learning to translate ‘colobus speak’ in Colobus Corner, and practising colobus leaps - which can span 50 feet – in Colobus Park.  Discover the Grade II* listed structure’s fascinating history and relax in our quiet zone.

The Snowdon Aviary was a landmark innovation in design when it was constructed in the 1960s, harnessing a combination of structural tension and balance to create an enormous space for birds and people to share.

The Grade II* listed former aviary is now enjoying a new lease of life in Monkey Valley, a new home for ZSL's eastern black-and-white colobus monkeys. The redevelopment was made possible by a £4 million grant from the National Lottery Heritage Fund.

Meet the Eastern black-and-white colobus

These fluffy-tailed monkeys are currently housed right next to London Zoo's Gorillas. Born entirely white, they change colour as they age, developing patches of black across their bodies. Expert climbers, look our for them swinging around on your next visit.


Icon for visual impairmentThere are four audio descriptions about Monkey Valley, developed for visually impaired visitors.

You can listen to the audio descriptions on your personal device as you walk around Monkey Valley or listen online using the links further down this page

They describe different areas of the exhibit, the colobus monkeys and their way of life. Each description is associated with a tactile object. You can listen to them in any order, as they are not an audio described tour around the site. 

Clear signage is used to signal the location of the 4 audio descriptions within Monkey Valley. The signs contain a QR code and a weblink which you can use to open the audio file.

We recommend bringing headphones, so when monkey sounds are played they will be for your ears only and not upset the real animals.

In the meantime, If you would like to join an audio described tour at the Zoo, please see dates and details on the link below:

Monkey Valley Information

Monkey Valley is home to eastern black-and-white colobus monkeys. They roam and leap through the iconic Snowdon Aviary, a structure originally built for birds in the 1960s, but now transformed to meet the needs of these tree-top dwelling monkeys.

There is a tactile and large print map on the Zoo’s West Footbridge, which leads over a canal to Monkey Valley. The location of the audio descriptions is marked on the map.

Occasionally the walkthrough section of this exhibit needs to close, to allow the monkeys to rest. You can still access the description outside the entrance and staff can inform you when it will reopen. Sometimes guides will also be there, leading small groups of visitors through the walkthrough.

Landmark new home for colobus monkeys unveiled ahead of August opening 

A colobus leaps from a rope ladder in the Monkey Valley walkthrough exhibit

ZSL London Zoo unveiled its landmark new Monkey Valley walkthrough exhibit this morning (July 28), revealing the iconic former Snowdon Aviary's transformation into a new home for Eastern black and white colobus monkeys – the first of its kind in the UK. 
ZSL Members Cat, Mason and Austin Avery were invited to a sneak peek at the unique walkthrough experience, ahead of its official opening on Monday 15 August - while keepers treated the lively colobus troop to an al fresco breakfast. 
Inside the soaring new canal-side walkthrough, visitors will be transported to the lush, mountainous forests of central Africa, and treated to 360-degree, panoramic views of the colobus troop, as they leap from tree to tree.
Soaring 80ft above the Primrose Hill skyline - the height of six London double-decker buses - the new walkthrough features a range of monkey upgrades, including multi-level sunny and shaded basking spots for the ten troop members to lounge in, more than 800 metres of rope to swing on, 1,347 new plants and trees to leap amongst and a 30ft waterfall, flowing into a peaceful lagoon. 
The exciting new attraction is also home to Colobus Park - a peaceful picnic spot, where parents can relax while little ones practise their own colobus leaps - and an interactive Colobus Corner, where visitors of all ages can learn to translate ‘colobus speak’, deciphering what their unique clicks and grunts really mean.

ZSL London Zoo’s Chief Operating Officer Kathryn England said: “We’re excited to welcome visitors to Monkey Valley this summer - after seven years of careful planning and restoration, new life has been breathed into the former Snowdon Aviary, a remarkable piece of the nation’s architectural history.  
“Colobus monkeys are nicknamed the ‘high-flying monkeys’, because of their impressive leaps - as they drop from branch to branch, with their arms outstretched, it's believed they use the long hair on their body and tails as makeshift parachutes. It’s truly a sight to behold, and we can’t wait to share this and more about these incredible primates with our visitors.”   
The Grade II* listed Snowdon Aviary’s restoration and transformation into the Monkey Valley walkthrough involved 35,000 hours of sensitive construction: abseiling experts carefully replaced over 1115sqft of aluminium mesh wrap, before deep cleaning the four towering tetrahedrons that create its distinctive shape and replacing 37 cables to provide the tension that famously holds the structure in place.   
The historic renovation will allow generations of future visitors and schoolchildren to get even closer to the amazing animals at ZSL London Zoo while forming a new conservation breeding centre for the troop - part of a collaborative European-wide breeding programme focused on the preservation of the species, which is threatened by deforestation in the wild. 
The ultimate immersive family adventure this summer, the Monkey Valley colobus monkey walkthrough experience will exclusively open to ZSL Gold Members, Fellows and Patrons from Saturday 30 July, followed by a public opening on Monday 15 August. Visit for more details.
