Taipei 101 from Elephant Mountain
The views from Elephant Mountain are insane. We went around late afternoon, so we were able to see the city during sunset and at night. It was perfect. In hindsight, the hike is relatively easy - if you do a quick search about this landmark, you'll know there are many steps, but there are also many resting spots and observatories for you to take the money shot. Not bad at all and totally worth it :)
