Comrades,
Work (science) takes me and a friend to Prague in September for about 5 days, and we plan to take an additional ~9 days to travel in Europe. We plan to use trains (Eurail?) to travel to the Alps region for the bulk of our trip.
We are but ignorant lads (~23 year olds) who need assistance to optimize the fun integral for our trip. Whence should we go, and what should we see?
When: September
Where: Alps, Switzerland, South Germany, Western Austria.
What: We are enthralled with nature and we like outdoor activities (hiking, backpacking, scenic mountains, forests, rail/train rides through the wilderness, and waterfalls). We enjoy interesting architecture, historical buildings, relevant historical places, and especially castles, cathedrals, and palaces. We will appreciate some museums and culture (but not excessive amounts). We like meat and ale.
Current Ideas: Munich, Salzburg, the Black Forest in Germany, the Alps x 106 , Jungfrau region in Switzerland, Neuschwanstein Castle, Passau. We will both have (backpacking) backpacks, and we both have backpacking gear that we could bring if you have good 2 to 3 day Alp backpacking trips you'd recommend. We are both seasoned outdoorsmen.
Fears/Restrictions: We aren't rich, but we aren't poor (so budget/middle of the range pricing is best). I speak some Spanish, and I can say "ambulance" in German, but other than that we communicate with English and grunts. We're mainly afraid of muscle atrophy due to lack of portable weight sets, and losing our passports.
tldr; In summary, we like a decent amount of things involving nature, cool architecture, historical towns, some culture, and everything to do with the Alps and beer. What should we do in the South Germany, West Austria, and Switzerland regions for just over a week?
