Religious Sites: One of the most popular Tibetan Buddhist monasteries is the Kapan Monastery that is located on a hill north of Boudha, Kathmandu. Plenty of travelers rock up to become students of Buddhism. From Kapan, you can plan a journey to Pashupathinath Temple - one of the four most important religious sites in Asia for the followers of Shiva. This is a magical temple complex and also the largest in Nepal. There is no shortage of religious sites in this country, so you will have plenty to do, see, and observe.
It's strongly advisable to wear more conservative clothing when visiting any temple or sacred space. Avoid skimpy, revealing outfits that expose your knees, cleavage, and shoulders. Men can get away with a t-shirt, but it's better to pair your trousers with a long-sleeved tee-shirt.
Meals: Most people don't dress up much for dinners in Nepal, so don't worry about getting fancy with your clothing. Do make sure to look decent, though! There are several 5-star hotels in Kathmandu (like The Dwarika’s Hotel) where you can wine and dine to your heart's desire, should you prefer something a little nicer than standard evening fare. Even for those, just dress appropriately for the weather and look put-together and you'll be just fine.
Outdoor Excursions: In Nepal you'll find endless trekking up and down the likes of Annapurna, Manaslu, Langtang, and Everest. You can also enjoy jungle safaris and other exciting adventures. Dressing for outdoor trips requires garments that allow for easy movement. For ladies, breathable t-shirts and leggings will do just fine, while the gents can get away with running shorts and t-shirts in the summer. However, if you decide to stop at a temple, remember to cover up. In the colder seasons, you’ll find that your hikes, cycling, and trekking will usually warm up your body naturally, but do keep a lightweight, foldable jacket and versatile hiking trousers handy.
Volleyball: The Nepal government issued a statement on the 23rd of May 2018 declaring volleyball the national sport of the country. The NVA (Nepal Volleyball Association) is headquartered in Kathmandu and represents Nepal in the Asian Volleyball Federation, as well as the Federation Internationale de Volleyball.
Because of these newer developments, you can enjoy volleyball, cricket, football, and other sports in cities and smaller towns. Games are hosted in most public spaces where larger crowds can be accommodated. For these events, keep it as casual as possible, but again: as a woman, you might want to avoid very revealing clothes. Men can wear t-shirts or longer shorts that hit the knee during warmer months.
