You can just google a country or city. But here's a few really informative and trustworthy places to find good travel info. Our four favorites:
Wikipedia

https://en.wikipedia.org
You can’t go past Wikipedia for general information about anywhere. It’s totally impartial, with ionformation provided by anyone who wants to post it and curated by a horde of willing volunteers. Too many sites are just promo pieces, paid for by the local tourist bureau. It’s not a travel site, but Wikipedia will give you the unadorned info about any location on earth. Pay them the ten bucks a month to keep them in operation – the place is a global treasure.
Wikiyoyage

https://en.wikivoyage.org
A Wikipedia style site that grew out of Wikitravel, founded in 2003. Now part of the Wikipedia Foundation. Built in the same way as Wikipedia, and optimized for information for the traveler. Excellent and impartial information.
TripAdvisor

https://www.tripadvisor.com
TripAdvisor has become the world’s largest travel site. Nearly 10 million people visit it every day. It has over 300 million members around the wold (it costs nothing to join), and has published over 500 million users reviews of hotels, restaurants, tours, attractions and anything to do with travel. Founded in 2000, it was one of the Internet’s first exponents of user-generated content. It has grown into a monster and is now a successful public company. It has moved way beyend reviews and now partners with all sorts of other companies to provide a wide range of travel booking services.
But it has stayed true to its roots. We love it, and we are in the top 3% of global reviewers. We use it lots, especially to check out restaurant and hotel ratings. There is no substitute for unadorned user reviews.
Google Maps

https://www.google.com
The best maps, with all sorts of overlays as well to help you locate hotels, restaurants and any type of business (like laundromats etc.) Contains reviews, but not nearly as extensive as TripAdvisor. We use it all the time. We often have TripAdvisor open on one screen and Google Maps on another.
Lonely Planet

https://www.lonelyplanet.com
In the Internet era Lonely Planet has managed to retain its edge. It is still the world’s largest publisher of travel guide books, and has expanded to online guides and advice. It was started in Melbourne, Australia in the 1970s by Tony and Maureen Wheeler just as the overland hippie trail was taking off, and now covers everywhere for everyone. Good, comprehensive impartial advice. Owned by US conglomerate NC2 Media.
