Da Lat is so much different from other places in Vietnam, you'd think you were somewhere in Europe at times. It was beautiful. It's the Flower capital of Vietnam as well, so there were flowers everywhere (loved it).
We visited a coffee plantation and had vietnamese coffee, SO delicious.
We visited a silk factory in Da Lat which was really interesting. First they start with silk worm cocoons, then immerse them in boiling water which separates the silk and then they unravel them with machines before the strands are dyed. Incredible!
The Crazy House in Da Lat is just that, a mismatch of crazy rooms and artifacts put together in a great and fun way. You can stay overnight in the Crazy House or just come for a visit and walk around to observe.
