While I didn't think to consult with my doctor before hiking to Machu Picchu, I did remember to bring sunscreen. Yeah for small victories! Yet, not quite so yeah. As soon as the sun's powerful rays started beaming on my shoulders, I realized I should have packed sunscreen with a much higher SPF protection.
Unfortunately, my shoulders became sunburned within the first couple hours of hiking, which made carrying my backpack extra painful at times.
In addition to a high SPF, I would highly recommend bringing a bandana, a hat, and sunglasses. Since you'll encounter various types of weather along the trail, these three items will come in handy.
