How can I tell if my child has altitude sickness?

Watch for loss of appetite, irritability, and refusal to play. If they complain of a headache or nausea, descend 1,000 to 2,000 feet immediately.

Do kids need specialized boots?

At a minimum, they need sturdy, broken-in hiking shoes with aggressive tread. Waterproofing is essential because mountain weather changes in minutes.

Packing for High-Altitude Trips with Kids

Prioritize rapid temperature regulation and hydration gear to combat thin, dry air and extreme weather shifts. Focus on a strict layering system and specific medications to manage altitude sickness, which hits children just as hard as adults.

Master the Base Layer. Avoid cotton entirely. Pack merino wool base layers for every child. They manage moisture, stay warm even if damp, and don't hold smells after three days of wear.
Set Up an Altitude First-Aid Kit. Include a pulse oximeter ($25) to monitor blood oxygen levels. Pack chewable electrolyte tablets and pediatric-safe headache relief. Consult your pediatrician about acetazolamide (Diamox) if you are traveling above 8,000 feet.
Prioritize Sun and Skin Protection. UV radiation is significantly stronger at high altitudes. Pack category 4 sunglasses for everyone, SPF 50+ mineral sunscreen, and intensive lip balm. The air is extremely dry, so bring travel-sized nasal saline spray to prevent bloody noses.
Pack Modular Insulation. Bring a lightweight down jacket that compresses into a small pouch, a fleece mid-layer, and a waterproof shell. Kids should be able to add or remove these layers without your help.
