I’m going to solo travel, so I tend to have extra time in case I have any problems. Didnt booked anything yet. Prefer to do it there, unless it must be prevously booked, but i think the only thing that maybe be sold out it would be Big Ice experience right? Any advice where to stay or experience that must do in this places? Is there any thing that maybe would take more time to do? I like slowly exploring places, especially walking or by bike. Love trekking and hiking.
Thanks in advance for any tips
