How we work:

Honesty and authenticity are important, which is why we only publish reviews of hotels and tours which we’ve had the chance to experience ourselves.

Hotels or tours usually host us free of charge, so we can experience them and participate, talk to their founder, manager or sustainability champion(s), and then prepare and write the reviews.

Recently we’ve switched to interviews as a more interesting way to tell the story of those businsess and the people running them!

Green City Trips How we work
Visiting the hotel property and talking to the manager is part of our approach.

Very rarely we also accept invitations from destination marketing agencies or tour operators, but will only feature and recommend those businesses which we consider a good fit for our readers.

Because achieving sustainability can be a long and difficult process, we don’t expect each hotel or tour to be at the same stage in terms of its environmental performance. We don’t see ourselves as “eco police” – more like scouts on the look-out for inspiring, enriching tours, accommodation and memorable experiences.

Since we started Green City Trips, we have reviewed anything from student hostel to five-star wellness resort, in places as diverse as Sydney and Melbourne in Australia, Auckland in New Zealand, Dubai, Barcelona, Lisbon, Berlin and Singapore.

Rather than focusing on how many stars a property has, we select our hotels and tours based on their potential to provide authentic, healthy and rewarding experiences. Visit our overview of city destinations covered so far.
