your question is pretty broad so it makes it tough to answer, probably why i'm the first to respond, but i'll give it a shot.
first if your ever going to be very far from a bike shop, then yes you should bring some basic tools atleast. also a pump, patch kit, spare tube and maybe a tire. and the list can go on from there depending on what your going to be doing. if your going to be camping you'll obviosly need some camping equiptment. again this can vary greatly depending on the kind of camping you plan to do. example will you be eating in resturants and camping, or cooking your own food.
best advice i can give is first figure out whre you'll be going and what you'll be doing, then start to plan from there. also read thru this forum and check out this web site
that will help you get some more specific questions together about your trip and plenty of folks here will be happy to try and answer
have a great time.
No matter how fast I'm going, I'm in no hurry.
there are no bicycles in the valley, the only bicycle you find in the valley is the bicycle you ride down there.
