Free and low-cost leisure activities in Ukraine

Hello,
it is really great topic but it is sad that no one share any ideas...
Well, I can start and present the way I look for cheap activities in Ukraine.
I am pretty new in this country, so I check many travel agencies who suggest [link moderated] and specific cities. Then I choose the low-cost tours and check all visiting places one by one. In this way I get a knowledge about popular places but find simple cheap way how to visit them.

Walking tours: in Lviv you can download a app on your mobile and walk around looking for the white arrows in town. You can listen to info about the buildings etc.

As an english speaker you could join an english-speakers club. They usually don't charge for native speakers and are happy you can help.

Children:
Beautiful parks - You can search 'playground' in Open Street Map. In lviv I recommend Ivan Franko park playground.

Many restaurants have playgrounds inside

Waterpark (free for kids but not for adults) -aqua lviv

horse riding - (this one is not cheap for Lviv but cheap compared to other countries): for one short ride is usually 50 - 100 Hrivnya. Or for an hour session is around 300 hrivnya. So expensive, but cheap compared to Germany for example.

Architectural museum - located in a forest - has many animals like geese, hawks, horses, rabbits, ducks, swans, 20 hrivnya entry. Turn up early.

Go cart racing - inside the architectural museum

Soap making - inside the architectural museum
