Since Prince Harry and Meghan Markle’s wedding in May 2018, the couple has been using their royal platform to bring awareness to many worthy causes. On their @SussexRoyal Instagram account, for instance, they promote a different group of charities each month. Recently, Meghan and Harry shared an update about one of the causes they support—and they even threw in some never-before-seen pictures from a previous elephant conservation trip.

In honor of World Elephant Day on August 12th, the Duke and Duchess of Sussex shared new photos on Instagram from a 2017 elephant conservation trip they took to Botswana. Along with many, many gorgeous snapshots of elephants, they also shared a couple of pictures of themselves working with the majestic creatures. They even added a few photos taken by Elephants Without Borders, the conservation group they worked with during the trip.

The royals wrote in their caption that Elephants Without Borders has been able to fit 25 elephants with navigation collars, thanks to awareness efforts from the Ellen Fund and their own followers.

Meghan and Harry also shared a statement from Mike Chase and Kelly Landen, the directors of Elephants Without Borders.

Even aside from Harry and Meghan’s work with Elephants Without Borders, Botswana has a special significance for the couple. Harry told People in 2017 that Meghan joined him in the country for five days “about three, maybe four weeks” after they started dating. He described the trip as “crucial” when they were getting to know each other.

We love to see Meghan and Harry using their platform for good. And as for their amazing throwback photos, we can’t think of a better way to celebrate World Elephant Day.
