We have a 19 hour layover in Iceland before heading home, so not a whole lot of time to spend there. I'm assuming that won't be enough time to do it? I looked it up and it seems like a several day hike, but something I'd love to do. If it is near Reykjavik and a portion of it can be seen in that amount of time I'd definitely be interested. We weren't originally going to do Iceland, but my friend wanted to see Reykjavik, so we were able to fit in a short time there with the layover.
Also, is it necessary to wear a Lederhosen to Oktoberfest? I think I'd prefer not to as long as I don't stand out and look like an asshole for not, lol
If you only have 19 hours no you couldn't do it, it's a mutli-day hike.
Here is what I would recommend if you have that short of a layover:
-Obviously see Reykjavik, there is one small main street you can walk up and down in a few hours if that type of tourist shopping and stuff if your thing. There is also a pretty church there. It's pretty typical main street though, and it's the ONLY place in Reykjavik you'll want to go lol
-The Blue Lagoon hotsprings. Super touristy and commercialized, but again it's a quick trip with buses that take you right there from the city or from the airport etc. It's a giant hot spring with a little walk-up bar, mud baths etc. I thought it was pretty neat. If you like the idea of hotsprings, but don't want to go the touristy route there are many others that are nice too, just do your online research to find one. Usually it's only locals that will go to these ones, but a few others are "commercial" just less touristy.
-You can go see the waterfall strip, and probably hike a portion of it...from the Seljalandsfoss all the way to whatever that town in. Also a primary tourist spot, there are much prettier falls but they are a bit more out there....may be pushing it with only 1 day getting there and back. You'd be on a bus for 90% of your trip which may suck.
-They have a great public bus system that will take you anywhere, including the trailhead huts and stuff, like in Thorsmork or whatever it's called.
-I can't remember if you can do it in a short time frame, but you can also check out puffin island.
In general there are lots of shorter hikes you can do, but keep in mind most are a 2-4 hour bus ride from the airport/city. So between the bus there and back and your hike your entire day is shot and may be cutting it close even as the buses only run at certain times.
As far as germany and oktoberfest lederhosen...no it's not required at all. I didn't. However a LARGE number of people do. I thought it would just be a few locals or officiandos or something, but no, a majority of people wear them. I will be next time as well.
