Enough - same as any other trail.

Ok, sorry for the smart reply. You'll need to pull out the maps and locate water sources. Once you know that, you can use your hiking speed to determine about how many hours it is between sources. Then, knowing how much you drink, you can figure out how much water you'll need for that amount of time.

There is no hard and fast rule, and no way anyone can tell you how much YOU need - if they've hiked the same trail, they might be able to tell you how much THEY need.

As an example, when I started out as an assistant Scoutmaster, I was told (by supposed experts) that I should always carry at least two quarts of water at all times. A couple of places we went, that was true (it was also the ONLY place my "experts" ever went.) But, when I started going to other places, I found that I would take my regulation two quarts from one source, and still have a quart and a half left when I arrived at the next source. Now, if it's about 3-4 miles between sources, I leave source A with a quart of water.

Of course, you'll want extra if you're going to camp between sources, or if you're going to need water to cook lunch between sources. How much? Depends on what you're cooking, whether you plan to use some of it for a sponge bath, etc.

Nice try, but we can't shortcut your planning for you. <img src="/forums/images/graemlins/wink.gif" alt="" />
