Insider timing tips
- •The 'green season' (May-October) offers lush scenery and significantly lower prices/crowds, but be prepared for daily downpours that can impact travel.
- •October marks the transition out of the monsoon; while still wet, it offers a balance of green landscapes and decreasing rain, with fewer tourists than the peak dry season.
- •The period from November to February is the most popular due to ideal weather, but this also means peak crowds and the highest prices for flights and accommodation.
- •While temples are accessible year-round, the dry season (November-March) provides the most comfortable conditions for extensive exploration without extreme heat or rain.
