I built this simple website https://unexploredhq.com to find interesting (less known) places to travel with my SO and family. Instead of searching for new places by name, one can search for new places in a region with simple attributes.

I have built the database by scraping some data online, and have a database of 60,000+ locations. The attributes are built with some basic ML and text processing, nothing fancy. But this is sufficient for me to do this search: find places in Europe where I can do surfing and hiking with a temperature of less than 25 degrees.
