Kate Middleton and Prince William took a walk on the wild side during the fourth day of their tour of India.

The royals went on a safari at the Kaziranga National Park in Assam, India, to "learn more about the challenges the park's facing from rangers," according to Kensington Palace's official Twitter account.

The couple looked out the roof of their car as they rode through the national park on a safari, spotting a rhino, swamp deer, and several exotic birds. They later visited with park rangers to learn more about the work they’re doing to protect the animals.

For the outing, the pair went more casual, with Middleton wearing skinny jeans, a white polka dotted top, and flats, and her husband wearing jeans and a grey button-up shirt. Upon their arrival, the Duke and Duchess were gifted with their own colorful scarves.

Following the safari, the couple got the chance to interact with the park's animals, evening feeding the baby elephants and rhinos. Middleton changed back into her signature wedges and a colorful dress, laughing as she and her husband gave the animals their food.

This follows an already successful tour of India for the royal duo. On Tuesday night, they were treated to two dance performances from locals at the Assamese Bihu Festival.

They also met with Narendra Modi, the Prime Minister of India, who later tweeted, “I had a very good interaction with the Duke & Duchess of Cambridge #RoyalVisitIndia.”

Middleton made headlines earlier in the week when she played soccer and cricket with local children while wearing wedge heels.
