I moved to CO this winter and have 7 trips arranged ranging from 2-4 days long. In my head I see this as quite possibly the most exciting backpacking summer of my life since I generally only planned one big trip a year when I lived in TX and that was usually with 2-3 other people. I have always wanted to do solo and don’t think I will have any issues with it although it would be a lie if I said I wasn’t worried about bears although this has never worried me before when hiking in groups.
Areas I will be backpacking – Lost Creek Wilderness Loop, RMNP (Twin Owls Loop + Grand Lake Loop), Maroon Bells (4 Pass Loop), Indian Peaks (Pawnee-Buchanan Loop + Arapaho Pass/Devils Thumb Loop, Rawah Lakes Loop
Should I carry bear spray due to the fact that I am alone (I guess another 12oz wont kill me)? Do all these places require you to camp in designated campsites since I see these as the riskiest places to camp? I know RMNP and Maroon Bells have designated sites, not sure about the others but would prefer to setup where I know bears are not conditioned to look first.
Thanks!
