Prince Harry is taking his girlfriend, Meghan Markle, to another African tourist spot.

Earlier this month, Prince Harry and Markle touched down in Botswana, where they celebrated the "Suits" star's 36th birthday. As part of their ongoing three-week vacation in Africa, the couple is reportedly visiting Zambia, this time to see the Victoria Falls, one of the seven natural wonders of the world, Daily Mail reported.

The waterfall straddles Zambia and Zimbabwe on the Zambezi river. It is one of the largest in the world, plunging 354 feet. The security and government officials in Zambia were reportedly "put on alert" that the royal and his guest were stopping by to see the country's sights. "VIPs love to take helicopter tours of the falls. It's one thing to experience them at ground level, but high up is where you really get to see how spectacular the view is and just how enormous it is," a local source said (via E! News).

Prince Harry apparently has their trip all planned out. "Harry knows exactly where to stay on a trip like this and he's also worked closely with a trusted tour guide who has helped with arrangements and organizing excursions," another insider told the publication. "There may be some luxury but there will be a big element of daring stuff, too. They just want to get really close to the animals and the people."

In related news, Prince Harry reportedly planned to propose to Markle during their three-week trip to Africa, according to two sources. The insiders told Us Weekly that Prince Harry intended to ask Markle to marry him during their getaway.

Although the royal has apparently been keeping mum about his proposal plans even to his pals, one friend claimed that Prince Harry wanted to propose on a date near his mom Princess Diana's death anniversary. This was apparently so Prince Harry "can associate August with something joyful."

There has been no confirmation regarding the engagement rumors involving Markle and Prince Harry. However, reports have it that official announcement of a royal engagement usually occurs a month after the proposal happens.

When Kate Middleton and Prince William announced their engagement, the latter admitted that he popped the big question to the Duchess of Cambridge during their trip to Africa, which happened a month prior to the public announcement.

The Prince Harry insider also told Us Weekly that he would want to keep the news to him and Markle for a while if ever they decided to get engaged. "Harry said he would want to enjoy the news between the two of them before word starts spreading out," the insider explained. "This has really been the trip of a lifetime."
