Hang Outdoors is an outdoor discovery and planning platform, established in 2011 and reimagined in 2026 to support people throughout their outdoor lives. Its catalog features more than 170,000 places, from fishing spots and hiking trails to waterfalls and campgrounds, alongside 28 activities spanning water sports, camping, nature study, cycling, and more. Interactive maps and planning tools help users find destinations, save places, build lists, and organize trips.

A free membership also provides a personal workspace with a journal, favorites, trip planner, and web clipper. Members can contribute places, sightings, notes, and business recommendations; new additions are reviewed for quality, and trusted contributors can publish without review. Five knowledge libraries cover animals, plants, geology, fungi, and astronomical objects, while outdoor guides offer practical information.

Hang Outdoors is developing mobile apps for iPhone, iPad, and Android, including offline trip planning and field observations. The platform also connects users with outdoor businesses such as guides, outfitters, campgrounds, marinas, and lodging providers
