For Becky Perlow, the next destination looms 19,341 feet above sea level. The goal? Reaching the top of Tanzania's Mount Kilimanjaro, located 3 degrees south of the equator and deemed by many the highest free-standing and "walkable" mountain in the world.

That's easier said than done, but Perlow's father, Howard, said he thinks his daughter will make it.

"When she sets a goal, she usually finds a way to complete that goal," he said.

Since 1991, Kilimanjaro-goers have been legally required to climb with a guide, so Perlow, 26, is hitting the hillside with the travel organization Adventures Within Reach and three other climbers, excluding the guides.

She will be accompanied by a CNN co-worker of nearly three years, Laura Koran, also 26.

They begin trekking the Machame Route, also known as the "Whiskey" route, on Tuesday and plan to reach the top at Uhuru Peak five days later, the ideal time to take to the mountain.

Koran's father, Donald, is the U.S. ambassador to Rwanda, which borders Tanzania, and she said she had been meaning to get out there to visit her parents.

"So Laura approached me several months ago and said, 'I want to hike Kilimanjaro,'" Perlow explained. "And I said, 'Me, too!' So I said, 'Why not? Let's do it!'"

"I've always wanted to climb Kilimanjaro but never really had anyone who wanted to do this with me," Koran said, laughing.

But Perlow is always game for adventure.

"I've always been an adrenaline junkie," she said. "I say I'll try anything once. So I've scuba-dived with sharks. I've jumped out of a moving airplane. I've bungee-jumped off one of the tallest towers in the world that you can legally bungee-jump off of."

Part of the dream

Kilimanjaro is just part of a larger goal for Perlow, who was raised in Pikesville and now lives in Washington: She wants to visit every country in the world.

"I got the travel bug, I guess, when I was 14," Perlow said. "My parents had taken me to Kenya and South Africa on a family trip. … That might have been the first time I traveled internationally. … I loved it; I loved every second."

So far, she has been to 25 countries. By the end of her upcoming trip to the continent where she discovered her passion for travel, that number will have risen to 30.

 “From [Kilimanjaro], we are going to Kigali in Rwanda, where we’ll be visiting Laura’s parents. We’re going to be going to the rain forest there; her parents will be giving us a bit of the tour. And I’ll be going to visit the gorillas on my own. After Kigali, Laura goes back. … I’ll be in Zambia for three days, then Botswana for a day and a half, then Zimbabwe for two and a half days ... then home” on March 4.

But the goal to visit every country didn't just arise out of a young girl's family trip to Africa; it surfaced, as well, from her father.

"I do truly read 10 travel magazines a month," Howard Perlow said. "But I don't get to all those places in those travel magazines. … [Becky] knows it's always been a dream of mine."

That's why he's happy to do what he can to help his daughter attain her goal, although he readily acknowledges his jealousy. Becky Perlow said her mother — "my slightly overprotective Jewish mother" — is also very supportive.

"They let me travel the world when I was 18 by myself in hostels with a backpack and, you know, my passport," she said.
