Hi, Mansi. Weather will be really good in October and yes one week is enough to explore major attractions. I would recommend 2 days for Thimpu, 2 days for Paro and rest at Punakha. It is absolutely safe however I will recommend you to hire a tour guide to blend in local culture.
Bhutan is beautiful. One week is good enough. Good for a solo traveller but would be definitely more cost effective if there are more people with you as the govt has a minimum spend per tourist criteria which you need to adhere to. So more the merrier and your per tourist spend slab comes down.
Hi Mansi, October to December is the ideal time to visit Bhutan as the air is clear and fresh with sunny skies. January and February are colder, but from then until April the climate remains dry and pleasant and in late spring the famous rhododendrons bloom spectacularly, flooding the valleys with colour. Travelers on Tripoto have been talking about this. Please click on the cards below to read their experience. Thanks!
1. The weather is good! A note on the permit - For citizens of India, Maldives and Bangladesh, there is no minimum spend of $250. It is only for other countries. Indians have to show their passport and get a permit. Would need to show a detailed itinerary and confirmed hotel booking. There is a permit office right at the border ( do make sure you reach early - Bhutan is 30mins ahead of IST and the office closes at around 5pm their time). Also check for holidays when the permit office will be closed. This permit is for Thimphu and Paro.
2. Extremely safe for solo women travelers!
3. 2 days in Thimphu, 3 in Paro and can visit Punakha too (need a separate permit for this)
