iOverlander is a mapping app to help travelers find camping and accommodation worldwide - no matter how remote your destination. Only real places by real travelers. Unbiased and never sponsored. There is no list or robot that can ever replace what a traveler says standing right there in that spot. Typos and all, we believe the best data comes from overlanders onsite. No signal? No problem. The best places on this planet don’t have cell signal. All our data is stored on your phone, so you can plan your day without wifi. Download offline maps of entire states and countries, that give you all the tiny alleys, building footprints, and small landmarks to make travel easier. Campsites are just the beginning. Mechanics, restaurants, hotels, propane, water, wifi, shopping, laundry, showers, doctors, tourist attractions, border crossings, warnings, checkpoints, insurance, storage, shipping, consulates, banks, and more. Moderated by overlanders, not AI. Our moderators have spent a collective century on the road and 30,000 hours moderating entries. They’re not planning to stop anytime soon. But wait, there's more! In addition to finding places, you can add new ones, leave reviews, save favorites, and share places with other travelers. Subscribe to iOverlander Pro or Unlimited to download offline maps, access satellite maps, BLM and USFS overlays, save filters, search and more! Wherever you're headed, we've got your next destination. ____ Terms of Service: https://ioverlander.com/terms Privacy Policy: https://ioverlander.com/privacy_policy
