I'll agree with CBS. While I enjoy climbing (and that's where I'll be spending most of my free time this summer), hiking certainly has it's place. If you don't like hiking, then you must not like a significant portion of climbing, considering how much of an approach a lot of climbs have. If you enjoy hiking, then you'll enjoy the whole experience, not just the a short section in the middle.
A hike for the sake of hiking, whether it's just doing Angels Rest or the Timberline Trail in a day, is certainly something worth doing.
(For the record, the best day of my life was a hiking day...)
