Clothing/Shoes/Weather Gear: Walking up a hill, walking down a hill and walking some more ... thats McLeod Ganj in a nutshell :) ... a comfortable pair of shoes is highly recommended.
Temperature tends to drop to near freezing point during the winter months. Heavy wollen clothing is required for the months of November through February.
Dharamshala also receives the highest rainfall in northern India (second highest in the country). The rainy months from July through September are best avoided.
Clothing/Shoes/Weather Gear: It can get cold up here, especially at night. However, if you arrive in high season, and come from a colder clime, then it should not bother you.
It does rain without warning here, and it rains throught the year. Londoners should feel right at home! :-)
Toiletries and Medical Supplies: Malaria pills, diarrhoea pills, gastric medicine! Pretty standard stuff if you're coming to India from the developed world. If not, you're safe!
Photo Equipment: Make sure you have a camera! There's too much beauty to not take home with you.
