Prince William and Prince Harry were such adorable boys when they were young.

During their vacation in the Caribbean with Princess Diana, the trio was photographed basking under the sun while sitting on the sand. In an unearthed picture, Princess Diana is wearing an animal print attire and sunglasses.

The Princess of Wales’ cheeks and arms are tanned from staying under the sun for quite some time. Sitting in between the late royal’s legs is Prince Harry, who is wearing a white shirt and swimming trunks.

Prince Harry covers both of his eyes using his hands since the sun is shining directly on his face. Sitting a few inches in front of him is his older brother, Prince William. The second in line to the throne is also wearing a white t-shirt and swimming trunks.

The dad of three is resting his legs in the sand, and he is smirking in front of the camera due to the terrible heat. The photo was taken when the royal siblings were approximately 3 and 5 years old at the Necker Island in the British Virgin Islands.

A couple of years later, Prince William and Prince Harry’s vacations with Princess Diana ended after the mom of two passed away following a fatal car crash in Paris. But the royal’s death never stopped her sons from exploring the world.

When they were teenagers, Prince William and Prince Harry were joined by Prince Charles in Klosters, Switzerland for a quick vacation. In the photo, all three male royals are wearing their winter gear. They are sitting on a bench after playing in the snow.

Prince Charles is seated in between and one row below his sons. Prince William is sitting on his dad’s right side, while Prince Harry is on Prince Charles’ left side. Prince William is wearing a blue winter jacket and black pants, while Prince Harry is in his black winter jacket and khaki pants.
