Most speculation has the couple, now the Duke and Duchess of Sussex, spending private time in Africa, a place of significance for Meghan and Harry.
"It’s believed they are spending some time in Africa, possibly Namibia, and potentially [taking] another trip after that as part of the honeymoon," said Roya Nikkhah, an ABC News royal contributor.
It was Africa where Harry, 33, whisked Meghan, 36, away just around four weeks after the couple first met on a blind date in London last July.
"I managed to persuade her to come and join me in Botswana and we camped out with each other under the stars," Harry said in his post-engagement interview with Markle last November. "She came and joined me for five days out there, which was absolutely fantastic."

He continued, "So then we were really by ourselves, which I think was crucial to me to make sure we had a chance to get to know each other."
Harry also included Botswana in Meghan's engagement ring. The main stone in Meghan's ring is sourced from Botswana, while the diamonds surrounding it are from the jewelry collection of Harry's mother, the late Princess Diana.
Harry shared last year that Botswana will always have sentimental value to him.
"I first came in 1997, straight after my mum died," he said. "My dad told my brother and me we were going to Africa to get away from it all."
"This is where I feel more like myself than anywhere else in the world," Harry continued. "I have this intense sense of complete relaxation and normality here."
The duke and duchess were married on May 19 at St. George's Chapel in front of around 600 guests and a worldwide television audience of millions.
