18 rain days a month finds every seam. A real shell, not a windbreaker.

A UV index of 5.3 burns exposed skin even under cloud cover on mountain slopes.

Glare bounces off wet rock and water after rain, making polarized lenses necessary for safe hiking.

Check ankles and, if there's a dog, paws and ears every night.

Mountain terrain and single-track roads mean sprains happen far from help, so carry bandages and tape.

This country runs on Type C or J. Get one with USB-C so you're not fighting over the single outlet.

Daylight runs only 12.6 hours, so charge devices at night when you can't shoot photos.

Set it up before you land. Signal drops for long stretches outside cities.

Overhead bins on every airline on this route fit a 35-45L pack, so skip checked bags.

Mountain day hikes from base camps need a separate small pack for water and layers.

Fits the overhead on every airline that matters. Skip the checked-bag line entirely.

For the passport, the chargers, and the one dry pair of socks.

Tap water stays drinkable, so a reusable bottle cuts plastic waste across the month.

One brick charges the laptop, phone, and camera.

One outlet per guesthouse means cables stay plugged in while you move around camp.

A few phrases go a long way. Ten minutes a day before you leave is plenty.

International travel requires documents at checkpoints, so keep your passport in one secure spot.

Shared accommodations and train stations mean locking your bag keeps belongings where you left them.

Humidity hits 80 percent, so hang toiletries to dry instead of leaving them in sealed bags.

Train rides through mountains last hours, and a pillow makes sleeping upright less painful.
