Jessica Biel climbed 19,340 feet to the top of Mt. Kilimanjaro in January 2010, and now she's set her sets even higher.

The 29-year-old New Year's Eve actress, who hosted the 6th Annual Charity: Water Ball in NYC Monday, said she hopes to one day join the few who have reached the peak of Mt. Everest.

"I have lots of things in the dream pipeline for adventures in the future. I've said this before, but one would be getting Everest base camp and trekking there," Biel told Us Weekly. "It's a 10-day trek up and down."

"It's actually a lot less than Kilimanjaro," Justin Timberlake's on-again girlfriend added. "I'm always interested in some kind of fun adventure."

Biel first summited Mt. Kilimanjaro with Emile Hirsch to raise awareness and funds for the global water crisis that has left one billion people without access to clean drinking water. She was joined at Monday's event by Tyler Perry, Sophia Bush and Erin Fetherston.
