I was wondering if it is necesary to print of the walking maps or can we get copies at trains stations or somewhere once we are there.
You can do either - The online maps tend to be specific to a single hike andd don't show alternatives, the Landeskarte for each area are available at newsagents, train stations, and most kiosks for 10-15 SF (good 1:25,000 topo maps done by the Swiss army).
Do you think we can do some walking later in the year. My hubby and I wont be there until last days of October and 1 & 2nd Nov. I guess its going to be pretty cold but it was then or never so we chose then.
Yes, but be aware that the weather is getting cold, and most of the Alps will be closed (Alps are actually the areas that the cows move to in the mountains), so places like Obersteinberg may be closed, although walking past it is probably still possible (barring early snowfalls).
I know we cant predict the weather but has anyone else been there at this time of year that can give some idea of what to expect.
I lived in Gimmelwald over this period a few years back. The reality is that each year is different. Many walks will be possible irrespective (Grutschalp to Muerren to Gimmelwald, but I'd check out the Gimmelwald to Stechelberg section with locals before starting - it has a section that sometimes washes away with heavy rain.
Lauterbrunnen to Wengen will be OK, Wengen to Kliene Shiedegg should be OK even if walking on snow. Just be aware that the bergweg (mountain paths) are primarily marked with paint on rocks, and may not be visible after snow. The main signs will still be visible, but if there is snow, stick to the wanderweg (walking paths) which are flatter, but also more commonly signposted.
If in doubt, ask the proprietors of the hotel before heading off.
