greetings from interior alaska....i will be in iceland for the month of august (on trail for about 15 nights) and heard the campground in reykjavik is pretty crazy but it sounds liike it may be fun for a night or two...also, i have a snowpeak stove that runs on isobutane and am wondering about the availability of canisters throughout the country...oh and one more thing if anyone has the knowledge....is it okay to drink untreated water there? i have not treated my water here in alaska for years.
thank you for your time

Here is some info on the kind of gas cartridges you can get in Iceland

They are generally available at gas stations and the like.
No campers treat water in Iceland for drinking, because there is plenty of the good stuff available, provided you are sensible about where you take it from. Coming from Alaska, I guess you'll know what that means. Obviously small streams tumbling down from the hills are best, they won't have passed any farming or human influence, and are well oxygenated to kill stuff off. What you may be unfamiliar is that in Iceland many of the larger watercourses have a heavy glacial sediment load, so in general larger watercourses are not a useful source of water, treated or not. And there are areas of Iceland with not much surface water available, because lavafields, sandflats, etc are often permeable, so check your route to make sure you will regularly encounter water sources - only going to be an issue on less well walked trails.
Most people do have to spend a night or two in Reykjavik as a matter of practicality of transport. You might even be able to pick up some half-used gas canisters there.

Have you checked Icelandic branch of the forum? I'm sure you'll find not only answer to your question about cooking but many other answers to many of your other questions as well :-)
