The daily tariff for visitors starting 2012 is US$250, whether you stay in hotels or go trekking. This covers all your accommodation, food, land transport within Bhutan, service of guides and porters, supply of pack animals and some cultural programs. The rate applies uniformly irrespective of location and the type of accommodation asked for or provided (which means if you get bumped from the fancy hotel you booked - which occasionally happens during busy times - you have no recourse). Groups of fewer than four people pay a daily surcharge, ranging from US$20 per person in a group of three to US$40 for a lone traveler. This covers all your costs apart from drinks, laundry and cultural splurges such as a traditional Bhutanese hot-stone bath.
Bhutan has 5 major banks (Bhutan National Bank, Bank of Bhutan, Bhutan Development Bank Limited, Tashi Bank, Punjab National Bank), with branches throughout the country. You can cash travelers’ cheques at any bank and most hotels, but you should only carry well-known brands such as American Express/VISA/MASTER. You can use your credit card, but only at bigger hotels and shops in Thimphu. There are ATM Machines where you are able to withdraw cash from your credit/debit cards.
Season
Bhutan has four distinct seasons. Each has its advantages and disadvantages for the visitor. Notice should be taken of the un-predictable weather patterns before making decisions when to visit. Remember, even predictable weather can vary dramatically in different areas and in 24-hours periods.
Spring is arguably the most beautiful time of the year to visit Bhutan. The fierce cold that is characteristic of the winter months tends to subside towards the end of February (around Bhutanese New Year, losar). Rhododendron begins to bloom, first in the warmer east. At the height of spring, the end of March, the whole kingdom comes to life with a spectacular explosion of colors; pink and white of the rhododendron blossoms are a common sight. The annual monsoons, from the Bay of Bengal affect the south and central regions in the months of June, July and August. The north is inhabited in the summer months, where the nomads return to the higher plains to tend to there Yak herds.
End of the monsoons, is yet another appropriate time to visit. It also marks the end of summer. The days are filled with glorious cobalt skies and pleasantly warm sunshine.
The autumn months of September to November bring shorter days and cooler evenings. The days remain lovely with crisp clear skies. Views over the high Himalayas are usually only possible from in September and March.
Come the end of November and the weather takes on its winter coat. The days remain crisp and nights turn cold. The southern areas, being at a much lower elevation, have a more temperate climate and considerably warmer winters.
Clear skies in the winter months bring with them cold weather and very windy afternoons but it is also the best time of the year to view the snow capped peaks of high Himalayan.
