How do I get there, move around and where to stay?
It is possible to get to Adrspach or Teplice nad Metuji by train relatively easy with only one change in both cases.With Prague to Adrspach trip the whole journey will take roughly 4 hours (change of trains would have to be in Trutnov). With Prague to Teplice trip journey will take roughly 3:20 (change of trains have to be in Starkoc). For both routes train tickets can be purchased via
Czech Railways eShop (same CD website will help with train schedules)
Also possible to travel both routes by bus only, however it will again require at least one change and won't be much faster (with Prague to Teplice actually traveling by bus would be even slower than using trains)
Between Adrspach, Teplice and nearest bigger towns (e.g Trutnov) you travel either by train (again CD website is of help to you) or by local bus (for instance schedule of some lines can be found
here and
here), thus as you can see there is nothing to worry about, local connections are rather frequent
For the hotels we usually recommend searching via aggregate websites like
hotelscombined.com, just enter "Adrspach" and it will show you hotels in Adrspach and near by areas
