Alright, it's not a secret, Prague is getting loaded with tourists. I would be tempted to say "don't go there", but it's a beautiful and unique city. It's worth a visit. So here's what I'll say instead: "go there at least once, but be smart and respectful".
The thing is, accommodation prices in Prague have gotten crazy.
So here's how to find a cheap place in Prague:
A 30-minutes ticket metro only costs 24 CZK in Prague! That's around €0.90! And look at the map, all metro lines (there are only 3) go to the city center:
30 minutes are enough to go from any station to the city center. The round trip will cost you less than €2 and you'll be able to save a ton of money on accommodation, whether you're in a hotel or an airbnb.
You'll notice that a lot of tourists have more respect for their Instagram account than they have for this awesome city, don't be like them.
Touch the sky from a hot air balloon as you enjoy views of historical castles, wild nature and other panoramas of the Czech Republic. From almost 1 000 meters up, enjoy views of the most attractive part of the country, Central Bohemia, all in the magical light of sunset or sunrise. Explore Chateau Konopiste and much more!
There's a good reason for why this is the most popular day tour in Iceland. Some of the main attractions are Þingvellir (our national park), Geysir (a frequently spouting hot spring) and Gullfoss (a very big, powerful and beautiful waterfall).
