Depends what you mean.

In travel, it's the destination. I hate traveling (although high speed trains are pretty cool!), but I love sitting on a beach or mountain or park or pool or lake or a unique bar/restaurant or some other place I've never been. The longer I'm at the destination, the more relaxed I become until finally I'm sad when I leave.

In cars or cycling or other hobbies, it's the journey. I love the new part install or repair but once I'm done I usually wonder if the change really made that big a difference. And then I do it again with the same result.
