The view from the mountaintop observation deck is quite nice, but Senko-ji Temple is further down the mountain. A word of caution: if you plan to visit Senko-ji, just buy a one-way cable car ticket; you can take the Neko no Shoso (Neko no Hossou) down the mountain on the return trip (but there won't be any cats, so don't expect it). Since you'll still have to walk down the mountain to get to Senko-ji, you wouldn't want to be out of breath after visiting Senko-ji and then have to climb back up for the cable car, right? It's much easier to just walk down the Neko no Shoso.
