Which area in Alsace has the most beautiful mountain scenery?

My fiance and I are going to Alsace in April and we are very fond of mountain scenery.

We would like to spend about 4 to 5 days in a romantic, peaceful and quiet village, which is not crowded. We have heard that Strasbourg is a beautiful city, but we would like to be somewhere smaller and less crowded.

We like Riquewihr and its surrounding mountains, but the information on this website stated it is quite touristy and crowded.

Would Riquewihr be less crowded in April? Any help with these questions would be greatly appreciated.

Thank you.
