Not sure if this post would belong here, but I'll be staying in Santo Domingo. I'll be going to DR next year and thinking of going to el Pico Duarte. Has anyone been up there? How long did it take you to climb up? Did you go through a tour company? Or on your own? I did read that even if you don't go through a tour company, you'd still have to pay a 'guia' in the park.
