Terrific pitures oddie225. Sounds like a terrific day to be there too.
You can collect the water from any of the several hot spring sources. Because the water has no minerals and is great for drinking when you get it from the source. You will need to let it cool first ;~) Most first timers can get it from the copper tube at the crab cooker pool source. It is a good place to try. Do you know where that is ? This way you can just bring in 2 2-3 liters, drink that and fill your bottles up for the return trip.
Glad 2 hlp !
