Day 2 involves visiting Huanglong, which is at high altitude.

Altitude sickness is manageable with preparation! We recommend: Drinking plenty of water (avoid alcohol/coffee). Taking it slow—don’t rush hikes. Bringing over-the-counter meds like acetazolamide (check with your doctor first). Packing warm layers, as cold worsens symptoms. Huanglong has oxygen stations near key spots (5-10 RMB per mask), and our guide carries a first-aid kit with basic supplies. Most travelers adapt quickly, but let your guide know if you feel dizzy or short of breath.
