Hi everyone, I'm travelling through Peru in September and currently have some ear issues. I recently saw an ENT specialist who said my right eardrum is slightly retracted. I also can't properly equalize pressure (my ears won't "pop"). A few days ago I flew to Lima from Europa without major problems. I used earplugs and only experienced some pressure in my ears, but no significant pain. I'm considering doing the classic Colca Canyon day trip from Arequipa. The tour goes from Arequipa (2,335 m) to Chivay (3,600 m) and includes a stop at around 4,860 m before returning to Arequipa. For people who have done this trip: - How noticeable are the altitude and pressure changes during the drive? - Did anyone do Colca Canyon with ear problems or Eustachian tube dysfunction? - Would you still do the trip in my situation, or choose a lower-altitude alternative such as the Sillar Route/Culebrillas Canyon? I'd really like to see Colca Canyon, but I also don't want to make my ear situation worse, taking into consideration I will fly to Cusco and do all the mainstream tours from there. Thanks! 🙏🇵🇪
