TrekEarth is an online community of travel photographers who upload their images to the site. The goal of TrekEarth is to learn more about the world through photography; it uses an encouraging critique system to enable users to comment on each other's photography. In addition to uploading their own images and critiquing those of others, members can upload post-processed workshop images. The site also contains forums covering topics ranging from tips and techniques to note-writing.

As of December 2011, the multilingual site hosts over 1,075,538 photographs from 192 countries across the world. TrekEarth is also related to its sister sites TrekLens and TrekNature, which cater to the creative and nature communities of photographers.

All photographs in TrekEarth are under the copyright of the members. Any use (commercial or not) requires permission. There is no close account option.
