When I see some nice clouds and possibility of a nice sunset, I usually go to some wide-open place to get a nice overview. Often times to the beach of course. The perfect scenario for me is the sunset accompanied by dramatic clouds. Horizon needs to be cloud-free for the sun to shine on clouds from below.
Here you can basically see the best scenario I need.
