What month(s) would it be good to give Yellowstone the first visit?
I was planning on going in around May and be there for around 6 days, hopefully it's enough time to see some stuff and if all goes well then I'll try to make another trip. I'd like to be able to do animal viewing, such as bears, wolves, bison and birds. I've read the guideline on the national park site for these activities...
Are there marked trails that one can easily follow for hiking on your own? was thinking of backpacking, but not sure yet. I'm almost sure that I'd be going alone, not ideal but don't have much options... I read another post on ranger guided tours and checked it out but some seem to be short guides of around 2hrs.
Also, which airport would be a good choice for arrival that have shuttle trips to the parks hotels?
Thanks for the help!
