I'm often asked about the difficulty of trekking or hiking to the suggested photo points, and while the answer depends on a number of factors, still -- all suggested locations are doable without any particular physical training or preparation.
Of course, while some of you may carry a lightweight camera, others prefer to have a heavy set of photographic equipment (I give my suggestions as to what I personally recommend in another section of this introduction), so you should consider in advance what you're capable of carrying up the mountain. Thankfully, most of the locations have comfortable cable cars that you can use but sometimes you'll have to hike up a little further up or down, so be prepared for some level of difficulty if you carry a lot of stuff on you.
Overall, the suggested itinerary is definitely not a hard-core hiking experience. It's a photography guide after all.
