Backwards, likely no. Unless some select physicists are correct that all of the past, present, and future exists at once and that only our senses give us the impression of time, that is.
Forwards will be someday in the sense that people traveling at high velocity age more slowly than those at slower velocity, and the effects of gravity can enhance the aging difference as well. When man has advanced to the level where we are able to build vehicles that can go near the speed of light, then it will be possible for a person in such a vehicle to orbit the Earth at that high velocity. And in doing this, a year to them would be several hundred years on Earth, so in effect they are "traveling" into the future
