You mention 150€/day in the comment thread. I'm struggling to think where in the world you couldn't stay on that budget if you spend some time looking for cheaper accommodation (hostel or something like airbnb) and mind a bit where you eat. Australia seems (per Wikipedia) to have the highest minimum wage at 18$/hour, ×8h to € comes to 127€/day. Sure, temporary accommodation costs like five times more than more permanent places, but in terms of food and transport you can pretty much do whatever the locals do so that, on the whole, you should be able to meet that budget pretty much anywhere

In Europe, Iceland might be the only place where you'd really have to plan ahead to get to an average of 150€/day as tourist. It's Europe's most sparsely populated country and lots of things need to be imported, making essentials like food expensive and accommodation options few and far between. If you don't want to drive a long distance every day (outside of the wider Reykjavík area at least) you'll easily spend three quarters of that daily budget on accommodation, and with food being expensive even in supermarkets and needing a rental car to get anywhere, you'll exceed the budget on a lot of the days

So that's challenge mode! I'm curious what values people who tried to cheapskate Iceland get to. We were at 290€/day for 2 persons. That's including the rental car, eating out most days (not at expensive places necessarily, but sometimes simply the only place), and we booked reasonably priced but not always the cheapest option for accommodation. This price excludes costs of attractions like the lava show, boat tour, swimming pool, etc.—the country is plenty beautiful to travel to without needing those necessarily, though I'd recommend all of the above. This amount is for 2 persons, but the car and rooms don't scale much when you're alone so a per-person cost price wouldn't be fair

What would you consider a low price level? My mom and I have been to a lot of places that aren't traditionally known as cheap, but we usually stay in places with a kitchen (aparthotels, mainly, we avoid airbnb) and grocery shop so we spend far less on food than a lot of people would. We also travel outside of peak season, primarily to avoid the crowds but it's also less expensive.

Czech Republic maybe, due to them having a different (and lower) currency? Prague is beautiful and Brno, while smaller, is quaint.

Jugendherbergen (Youth Hostels) are everywhere in Germany, making travel affordable even in expensive cities especially if you're under 28 and/or don't mind sharing a room.

The same might apply in other countries, I wouldn't know. Except in France where I know it's not the case because they are sadly underfunded.

Low price compared to what currency? That's the key question.

Hungary

Just avoid anything that isn't Budapest x)

Here are some pictures:

Vilnius has a very nice old city centre, great food and very good beers. It's pretty cheap and might fit in well with a round trip in the baltics. Haven't been to Latvia or Estonia yet, but the people I know that have been, have been pretty positive about it.

Greece

Eastern Europe tends to be cheaper but you can travel on a budget in most places.

Never heard of fees to enter a city before apart from the ETIAS fee for some countries which is somewhat like the ESTA but cheaper I think.

Only fees I've ever heard of were fees for violating clean air districts with a car that hasn't paid the tax or didn't qualify.

I've traveled all over Germany and never was charged a fee to enter a city.

Portugal, Bosnia and other get non-EU Balkan countries are good. You'll still find people backpacking there. Most of western Europe is too expensive for that.

150€ will net you a stay in most countries in the EU except scandinavia and too big cities.

For 150€ a day, Budapest, Warsaw, Split, Prague, Vilnius, Salamanca, etc.

Be mindful of where you rent, make sure to have travellers insurance, don't get scammed for BS reasons (like peeps trying to make you believe you need to pay high money to use the autobahn in Czechia). Be mindful of pickpockets anywhere southwest of Paris and enjoy the food and locals.

Albania. In particular southern Albania near Greece. Most places are good, but if you like the beach, Saranda. If you like history, Gjirokaster.

Dunno current status, but a few years back Croatia was a popular place to visit. I don't have the details, but it was recommended to me at the time by multiple parties of the reasonable cost range.

Please, if you don't have any experience traveling in Europe, don't reply to my post. I don't want to reply to any asshole who tells me to use Google to search. I think these people are born with a lack of ability to communicate with others.
