Hello! It sounds like you are planning an exciting trip to Nepal.

Best Time to Visit:
The best time to visit Kathmandu, Bhaktapur and Patan is during the post-monsoon autumn (September to November) as the skies are clear providing excellent views of the natural beauty. Late spring (March to May) is another good time when temperatures are warmer and the rhododendrons are in bloom.

Route and Accessibility:
Kathmandu, being the capital city, is accessible via Tribhuvan International Airport. You can find flights from most major cities around the world. From Kathmandu, you can use local transport like taxis or rickshaws to visit Bhaktapur and Patan which are suburbs of Kathmandu Valley.

Accommodation and Booking:
You can find a variety of accommodation options in Kathmandu, ranging from budget guesthouses to luxury hotels. Booking in advance is recommended, especially during the peak tourist seasons (September-November and March-May).

Clothing and Essentials:
Clothing should be in line with the season: jumpers and jackets for winter (December to February), and light clothing for summer (June to August). Essentials include a good pair of walking shoes, sunscreen, mosquito repellent, and any personal medication.

Health and Safety:
Consider getting travel insurance covering medical evacuation. You should be up-to-date on routine vaccines before traveling and certain additional vaccines may be recommended, kindly consult with your healthcare provider. Always drink bottled water and avoid street food if your stomach is sensitive.
