Oslo, Norway 
in $470s-$490s RT

Exploring Oslo is definitely a scream, but Norway's natural splendor lies outside the city.
It’s really all about the fjords!
There are a handful of those glacial valleys right by Oslo, so you need not travel far to feel like a Viking. But if you’re up for a proper adventure, you’ll want to hit the West Coast and work your way north, starting in Bergen. The colorful coastal town is like Norway in a nutshell, with charming cafés, cobblestone alleys, and historic harbors nestled along the water.
You could stop there and have an incredible trip, but you’ve still got a seemingly endless array of otherworldly coastline to admire. The views get REALLY crazy once you cross into the Arctic Circle – unbelievable that places like this are even real, but that’s Norway for ya :-)
Jack's take
Europe under $500 RT is a rare sight these days, so we'll take these flights to Oslo any day. Norway is also a great starting point to explore Scandinavia.
