Develop a few trusted sources for general place information, but also for specific travel (and other) interests. For travel, I like to look for results from The Guardian and The Telegraph (newspapers) and sometimes I include the word guardian in my searches. But you might go to sources like Outside Magazine or Cruise Critic. Personally, I skip Trip Advisor and Yelp.
Of course, related to this, suggestions from people you actually know, who have been somewhere, are the best. Even then, you have to ask yourself if their perspectives are likely to match yours.
Go slowly and be picky. Skip some of the top results and be ready to go to page 2 and beyond.
Cross-check your results. If a website tells you about a great place or organization, search again on its name, both to look for agreement and, if you decide it's a good bet, to find more places that are co-recommended.
Also, by the way, as an academic-type person, consider searching Google Scholar (or our fun databases, like APPsearch, if you're still in school). It can be interesting to know what scientists and historians are looking at in your region.
And check the local news. Something might be happening.
