We have some friends that are interested in taking a bus from Lima to Arequipa. Having not done this yet, we wanted to defer to you guys for suggestions. What are some good bus lines to look into? What are good prices? What should they expect time wise?
I will second that recommendation. I've also used Cruz del Sur many times and they were hands down the best compared to any other bus line I used. If you search this forum a little, there have been many similar threads for bus recommendations, and you'll see that Cruz del Sur is always the most recommended - along with Oltursa. I wouldn't use any other line. I even wrote an article about it - Bus Travel in Peru
