Mostly known for its world-famous two week long Jazz Festival  (a bit of a misnomer: you're just as likely to catch David Bowie or Beck as, say Steve Coleman), Montreux is well worth a wander through, if only to get to the scenic Château de Chillon or to get to the hiker's paradise of Hauts de Montreux.
Geneva Cointrin International Airport (IATA: GVA) is the closest major airport to Montreux, and serves direct flights from most major European hubs, as well as a few cities in Canada and the United States, North Africa, and the Middle East. From Geneva, it's a little more than an hour by car, and less than an hour by train.
The Railway Station in Geneva is connected to Geneva International Airport. From the arrivals hall turn left (inside the building) and you will walk through a shopping mall where the railway platforms are one floor below.
Montreux is served by direct rail services from Geneva, Lausanne, and Brig-Glis, and is easily accessible via rail connection from almost anywhere else in Switzerland. See the SBB site  for timetable info.
Montreux-Oberland-Bernois or MOB This is one of the longest established of the Swiss narrow gauge railways and runs from platforms 5 and 6 of the town's main line station to Zweissimmen via the resort town of Gstaad. Over recent years to company, which operates 1/3 of the Golden Pass route to Lucerne along with the BLS and the Zentralbahn brought under its sales banner the cog-wheel Montreux - Glion - Rochers-de-Naye Railway and its associated funicular from nearby Territet, the Les Avants - Sonloup funicular and the lines of the former CEV from Vevey into the hills.
Note that the trains on the Rochers-de-Naye line stop running to and from the top around 6PM but they'll shut down early if the weather's bad, so don't count on one to carry you out of a sudden early evening rainstorm.
The MOB operates not only local, stopping, trains but a regular service of panoramic trains with coaches having large picture windows and glass sections reaching into the roof, great for the views. Twice a day the line runs a classic service using either original coaches built before World War One or some built later to the same design, a throw back to the days of the Orient Express. First and Second class fares, single and return, are available on all trains with no extra charge for the panorama or clasic trains. Well worth the ride and a cup of tea or coffee in the buffet car.
The best deal to date has to be the jazz train, which runs on various days throughout the jazz festival (see above). The train goes from Montreux to Gstaad, and you can buy tickets for three of the carriages, where jazz bands play live during the journey. Once in Gstaad there is an opportunity to sample some local products and pretend to be a millionaire (Gstaad is that kind of place) before a return trip with more live jazz. In 2008 this trip cost 50CHF, which is only 2 francs more than the regular journey.
Pretty much anything heading North and/or East of Montreux will lead to some combination of charming Swiss villages, such as Château d'Oex and invigorating Swiss landscapes. Despite the heavy Golden Pass advertising scheme, most of the visitors are small groups of locals, not the hordes of tourists you'll find in near-by, but hard to get to Chamonix or Interlaken. Many of the mountain-top restaurants double as 'buvettes' - something between a refugee hut and a hotel - where you can stay the night, often for much less than you'd pay for a lakeside hostel.
Château de Chillon, Avenue de Chillon 21 (Veytaux-Chillon station), ☎ +41 21 966 89 10, . 6PM daily. A historic castle and the country's most visited place, on a small island in Lake Geneva only a few meters from the shore. It was built originally to allow the occupants to extract a toll from people and goods passing between Italy and the rest of Europe on the road north from the St. Bernard pass. The roadway here is wedged between the lake and the cliffs, so there was no way to get around Chillon. The Castle is more famous in modern times for having inspired Lord Byron's poem, The Prisoner of Chillon, based on the true story of François Bonivard, a political prisoner from Geneva who was released in 1536. Byron is said to have carved his name in one of the columns in the dungeon where Bonivard was detained during a few years. The castle is 45 minutes walk from Montreux along the lakeside, or 4 minutes by train.edit
Marmots' Paradise, . The mountains around Hauts-de-Montreux are threaded with forest trails, isolated villages, caves, grottos, and wildlife. Rochers-De-Naye itself is home to an odd little compound called "Marmots' Paradise" where marmots from all over the world live in an observable system of underground burrows. Any of the train stops will lead to several hiking options. For a real hiker's hike, tackle the four hour, 1000 metre climb from Caux to Rochers-De-Naye. Saner folks might want to get off at Dent-De-Jaman, just below the peak, where you can enjoy the views and fresh air with out the huffing and puffing. You can walk the trails up there which are not difficult, one being accross to The Alpine garden which is very beautiful with nearly 800 varieties of plants & flowers.edit

Take a journey at the "alpage"
Up High but not so far away, spend a night at a true "alpage", have a dinner with the "armailli", sleep on straw, and if you are awake early enough, milk the cows, watch the cheese making on woodfire and if you are lucky turn the "batte à beurre". Nothing can beat a spoon of cream (real one!)served with a wooden spoon (a real one!) carved by a local artisan (real one!). Don't miss the L'Etivaz cheese, of course.

Every Christmas Montreux hosts an excellent Christmas market for several weeks over the holiday period. The main road through the town (Grand' Rue) and the lakeside path are lined with wooden chalets where you can find anything to buy from local wine (free tasting sometimes on offer) to chocolates (of course) and local crafts. The atmosphere is magical, your kids can visit Pere Noel (Father Christmas)and in 2006 they also had a ferris wheel and an ice skating rink to add to the fun. With all the regular shops also open you could do all your Christmas shopping in one trip and get some unique presents into the bargain.
For the cheapest souvenirs in Montreux, check out the Kiosque Biblique, which is housed in a small wooden chalet next to the Eurotel. It's not always open because it's run by volunteers, but it always offers a friendly welcome to everyone and has lots of free Christian literature in many languages.
Coop Grocery store offering a range of sandwiches and salads.
The Coop is a few yards to the right of the exit to the railway station.

In here there are two supermarkets (Migros and Denner) selling sandwiches .
