Even if those planets are quite far away, if we are able to go really fast (as near as possible to C), and plan for a 1-way trip, we could reach nearby stars. Constant acceleration and time-dilation effects can make the trip less-than-a-lifetime long, for the voyagers anyway (but not for the observers left behind). At least that is my understanding; the main problem is that it takes a heap of energy for that constant acceleration.
