Where to go from Paris for 3-4 nights?

In Norway I'd specifically recommend https://en.wikipedia.org/wiki/Lofoten, a series of remote islands in the northern half of the country, west of Bodø. I can specifically recommend the http://www.tripadvisor.com/ShowUserReviews-g612444-d1238144-r115328714-Reine_Rorbuer-Lofoten_Islands_Nordland_Northern_Norway.html as a hotel and home base. It looks like a warmer Iceland; dramatic mountains, less snow and more grass. Really great. Another remote part of Norway that's interesting and beautiful is https://en.wikipedia.org/wiki/Senja, called "Norway in miniature" because it's a big island with a lot of varied geography. Both Lofoten and Senja are great rural getaways with nice hotels and restaurants for tourists. If you'd rather have a more urban experience, going to Bergen and doing the Norway in a Nutshell round trip from there is also terrific. Be aware that Norway is quite expensive both intrinsically and because the currency is expensive. If you want really remote and stunning, the https://en.wikipedia.org/wiki/Faroes are a beautiful place for a short visit. Also similar geography to Iceland but even more remote and tiny (and warmer). There's not a lot to do there exactly, but if you stay in Torshavn and rent a car to get around you can see a lot in a few days. Iceland is a great place to visit! Three days feels like an awkward amount of time though; a bit too long to just hang around Reykjavik, but not long enough to get out and see the rest of the island. I have friends who've spent 1-2 weeks driving around the https://en.wikipedia.org/wiki/Route_1_(Iceland) who thought that was great.

You mentioned somewhere that looks like Iceland, but Iceland isn't on your list. So, why not Iceland? Its less than 4hrs flight I believe. I visited Stockholm this summer, and had a fantastic time. No need to rent a car, and 3-4 nights is a decent amount of time. Take the airport express train from Arlanda - it drops you off right in the center of the city. The city is gorgeous, and we loved taking boats to various islands in the archipelago each day. There are so many destinations and tours, you can find something that suits your taste. Something that's on my bucket list and might fit your criteria, is to go to Norway and take one of the spectacular train rides along the fjords. http://www.norwaynutshell.com/en/explore-the-fjords/norway-in-a-nutshell/.

My bias is always for Prague, but you should choose one of the places you mentioned, since they already strike your fancy. So, how to choose? Well, when during the summer would you be going? Because Spain (and Italy, and Greece, etc) absolutely suck during August, with the heat and the humidity. Have you been in Northern Europe during the summer? I didn't look at your profile, but let's assume as we usually do here on MF that you are from the US. I'm from California, and one of my most favorite things about being in northern(ish) Europe in the summer was the long long day. It can be magical if it's something you aren't used to. Plus, the people are so happy during that time, every day feels like a party. Sorry that I don't have more specific recommendations.

Barcelona should be less than a four hour flight and I really can't recommend it enough.

Sorry -- yes, Iceland definitely interests us and we'd love to hear if there is a great place there for a short visit. This would be for early summer.

Berlin is hugely underrated and a really fun city. Ignore any preconceptions you have about Germany. It is German like New York is American. Seville is beautiful, and you could also do a day trip out into the countryside. But it will be boiling in summer. Helsinki makes for a great summer trip because the weather might be good and the days will be long. It's also not horrifically busy. Everyone seems to recommend the Fabian Hotel. Out in the countryside the mosquitoes are something else though. Iceland is great and you could mix up a day and a bit in Reykjavik with time seeing some of the countryside in the http://en.wikipedia.org/wiki/Golden_Circle_(Iceland). It's stunning and lush in summer although equally lovely in the depths of winter. By the same token, the Scottish Highlands and Islands would also be lovely, but beware the midges. You can either stay all the time in Reykjavik and day trip, which lots of people do, or head out for a couple of nights somewhere down on the south coast road - Hella, Selfoss or similar. Lisbon is a brilliant short holiday destination too. If your 3-4 days could stretch to 5 then I'd also suggest Slovenia - a couple of days in Ljubljana and then up to Bled, which is stunning. If you've got the cash http://www.brdo.si/en/vila_bled/introduction, Tito's old summer home, is great to stay in.

Seconding joh's suggestion of Norway in a Nutshell - I am dying to do that and 3-4 nights would be perfect. Unless you don't mind being hot, I would not go to Spain in the summertime.

Hm...you mentioned Finnair and Iberia so I'm guessing your miles are on a OneWorld partner. Direct flights on OneWorld airlines from Paris CDG and/or Orly are (according to the Orly/CDG Wikipedia pages): - Madrid, Barcelona, and Tenerife on Iberia - Berlin on Air Berlin (and Vienna on Niki, an Air Berlin subsidiary) - Amman on Royal Jordanian (probably juuuust outside your four-hour limit?) - Helsinki on Finnair - London on British Airways The questions to answer, then, are: 1) Are you willing to connect, or do you want a direct flight from Paris? 2) Are you able to book flights on other OneWorld partners with your miles? If connecting isn't beyond the pale, the tickets are free/free-ish because you're cashing in some miles, and the connections are good so you don't spend days in airports, consider these options... • Moscow or St. Petersburg - Finnair via Helsinki, British Airways via London, or Air Berlin via Berlin You'd need tourist visas but they are simple enough to arrange if a bit expensive, depending on your passport, and the flight's a bit longer than you'd want - but you'd have a pretty packed few days! Moscow and St. Petersburg might be the places best connected to OneWorld airlines within a five-hour range you haven't been yet/don't want to go to, and if you're looking for availability for a miles-redemption ticket you want more airlines on the route! • Istanbul will not be unbearably hot at least early in the summer (and is Rome #2, and is stunningly beautiful and historic.) Weirdly, the only OneWorld way there from Paris is British Airways via London. • Budapest is gorgeous and still relatively inexpensive. British Airways via London or Air Berlin via Berlin. Also: Kraków is doable on Air Berlin via Berlin. Probably longer/worse connections: • The Åland Islands: Finnair to Helsinki, then Finnair subsidiary FlyBe Nordic to Mariehamn - not sure if this is doable with OneWorld miles as only some FlyBe Nordic flights are operated on behalf of Finnair. • Bergen: British Airways via London or Finnair via Helsinki (though this is really indirect!). The fjords might be better-accessible from Stavanger - and British Airways via London is the only OneWorld way to get there.
