Can I travel to Amsterdam from the UK from the 12th of November to the 24th of November 2020?

Depends on where you are traveling from.
The coffee shops are open but there are certain rules you must abide by.
– Coffeeshops are open and permitted to sell weed and hashish at a take-away counter.
– They must be able to arrange this logistically and also observe all hygiene measures prescribed (such as maintaining a 1.5 metres distance between people).
– Customers are now only allowed to pick up weed and can not stay in the coffeeshops or use the shop’s facilities.
– Delivery is not permitted.

i would ask the airlines about it
