You may do a bit of sightseeing on holiday, or you may do a lot of sightseeing, but you will probably go to a museum or art gallery, and see or visit some of these things:
Many people go on a sightseeing tour of a town (usually in a bus); they can also go on a tour of the castle / the cathedral / the art gallery, etc. When you are sightseeing, it helps to buy a guidebook (= a book of information for tourists) and a map of the town you are in.
Things that tourists often do on holiday:
look round the shops / have a look round the shops
spend a lot of / lots of money
buy souvenirs (= typical products from the country)
get lost (= lose their way)
go out most evenings (= go to different places for social reasons, e.g. restaurant or disco) have a good/great time (= enjoy themselves)
The word place is very common and can describe a building, an area, a town, or country: Bruges is a lovely place (= town) and we found a really nice place (= hotel) to stay.
The town is full of interesting places (= areas/buildings).
These words are often used when we describe places:
Venice is beautiful but it’s always packed (= very crowded/full) with tourists in the summer. New York is very cosmopolitan. (= full of people from different countries and cultures) Vienna has lots of historical monuments. (= places, e.g. castles, built a long time ago) Many beautiful cities have become very touristy. (= a negative word: ‘too much tourism’) Sao Paolo is a really lively place (= full of life and activity) and the night-life is fantastic.
Note: If you want to ask if it is ‘a good idea’ to visit a place, you can use worth + -ing:
A: If I go to Scotland, is it worth spending a few days in Glasgow?
B: Yes definitely. And if you want to travel round a bit, it’s worth renting a car.
