We have done four separate 2-week trips to Switzerland, focused on hiking, and have never yet visited Ticino, Appenzell, or the Engadine. We don't like to move around as much as Rick's 14-day trip suggests, so we stick with a more compact trip in the Berner Oberland and Valais regions, adding Suisse Romande once. If you would like to follow Rick's suggested route, which requires a lot of train/boat time, the good news is that in September you can get 2-for-1 Flex passes. The offer is for the 4-day Flex, which you can use to cover the four longest travel days, and all others will be 50% off. Or you could get several successive 4-day Swiss passes but that would cost a lot more, and if you aren't on the move every day the Flex passes are a better deal. As for what to add to make a 3-week trip, two of our favorite places that are off the RS radar screen are Kandersteg and Bettmeralp. Kandersteg is a pretty village with lots of great hiking right from town, and a beautiful alpine lake above with more hikes. See www.oeschinensee.ch for photos. There is also a great biking opportunity here: rent bikes and ride into the adjacent valley, the Gasterntal, which is undeveloped and lovely. There are a couple of mountain inns there that offer lunch or snacks if you like. At Bettmeralp, you will find a car-free village perched high above a valley, similar to Mürren. Behind the village rises a ridge, and just over the ridge is the incredible Aletschgletscher, Europe's largest glacier. This starts on the south side of the Jungfrau, at Konkordiaplatz, and flows south before making a 90 degree bend to the west. There are hiking trails along the glacier and to various highpoints for views. If you hike up the Eggishorn you can look up the glacier north to the Jungfrau, then stop at Kühboden for a milkshake on your way home. www.bettmeralp.ch We typically spend 3 nights at each of these places.
