I'm planning this trip for late october like the title says. It's a quite popular route for cyclists, but my first time doing it. There's lots of small towns along the way but a tent and a good sleeping bag is a necessity, specially when climbing the Andes. I calculate something about 10 - 15 USD per day budget, or even less than that if some nice people are willing to host us on the way. Please let me know if you're keen to join me. Cheers!
