Edinburgh Zoo's new penguin enclosure is being opened to the public on Thursday following a £750,000 revamp.
The outdoor pool, called Penguins Rock, offers improved viewing areas for people visiting one of the zoo's most popular species.
For the penguins themselves, the attraction has mock sandy beaches and rocky areas, a waterfall feature, a water shoot and a diving board made out of carved rock. The development also includes a "state-of-the-art" filtration system for the 1.2 million litres of water it holds.
Colin Oulton, team leader for birds at the zoo, said: "The new enclosure is a wonderful addition to our visitor attraction and perfect for our penguins.
"The birds, both returning and new, have settled in very quickly to the Penguins Rock. In fact, breeding season will shortly be here and many of our returning birds are already claiming their favourite nesting spots."
Zoo bosses said the existing pool had served the zoo's large colony of penguins well for more than 20 years but it was starting to need some work behind the scenes, so it made sense to combine it with a visual overhaul.
Darren McGarry, head of living collections, said the animals have been getting used to their refurbished enclosure in recent weeks.
"Our penguins have been reintroduced back into their home over the last few weeks, with the 28 gentoos and 27 rockhoppers that remained at Edinburgh Zoo going in first," he said.
"It was a pleasure to see the birds start to interact with the new features of their enclosure - trying out the water slide and sticking their beaks into their new waterfall. The waterfall has actually proved to be a real hit with the gentoos."
He added: "It is the opportunity to feel so close to the birds due to the new lowered sightlines, and glass barriers and wood perimeters, that we particularly hope people will be thrilled with."
