When to go
The best months for hiking are Mar-Apr. Many hikers also visit in summer (Dec - Jan) along with non-trekkers so it can be very busy at that time. Days are long and mild then but it can be windy, as in spring (Sep - Oct). For non-hikers, a visit at any time is recommended outside the winter months Jun - Aug when it can be very cold and access routes can be blocked by snow. On the other hand, it is frequently less windy in winter and you have a better chance of spotting wildlife as there are few tourists around. Many facilities are closed then; however, each year, a few more stay open to cater for this off-season traffic.
