There is no single best month for every traveller. The right season depends on whether the priority is open roads, trekking, festivals, photography, quieter villages or winter landscapes.
Late spring and early summer
Days begin to warm, tourism services reopen and some overland routes may become available as conditions permit.
Mid-summer
This is a popular period for broad route access, though major destinations can be busy and weather can still change quickly.
Autumn and winter
Clear light and quieter travel can be rewarding, but cold, reduced services and transport disruption require more preparation.
Check current conditions. Road openings, weather, permits and flight operations can change. Confirm with official and local sources close to departure.
