The Adventure Guide Navigator app contains the largest collection of over 1,000 adventure routes and 4X4 tracks in the South Island – from scenic tarmac roads through to challenging grade 5 tracks. And that’s not all, it also has all the best vehicle accessible campsites, remote huts, fuel stations, and points of interest. TRUE OFFLINE NAVIGATION The Adventure Guide Navigator App comes preloaded with everything, ready to go. This includes an offline topographic map, plus all the routes, campsites, remote huts, fuel stations, and points of interest. This is a true offline navigation app, allowing you to navigate anywhere in the South Island without an internet connection. DESIGNED FOR VEHICLE NAVIGATION The app has been specifically designed for vehicle navigation. It features large zoom-in and zoom-out buttons, plus the simplicity of one touch navigation. GENUINE, TRUSTED RESOURCE Adventure Guide Founder Josh Martin, has ridden over 350,000 km on various adventure bikes while exploring the South Island, and personally logging, photographing, grading, and documenting every route, campsite, hut and point of interest. You’d be hard-pressed to find anyone who has travelled the South Island as extensively as Josh. All of this firsthand-gathered information is loaded to Adventure Guide, and is the reason why it has gained the reputation as the most trusted adventure resource over the past 15 years. The Adventure Guide Navigator App bundles all this information together in the convenience of an offline device, that you can use for navigating to the South Island’s most magical and remote routes, and destinations. MILD TO WILD Josh is a skilled rider, which allows him to log ALL the best tracks from scenic tarmac roads, to wildly challenging grade 5+ tracks. This means Adventure Guide has everything an adventurer could ask for, whether you are looking for a scenic style adventure, or looking to challenge yourself on a grade 4 or 5 track that leads to a destination that very few people ever reach. SOMETHING FOR EVERY ADVENTURER While the Adventure Guide Navigator App is perfectly suited to Adventure Riders, 4X4 Drivers and Overlanders, it is also an invaluable exploration tool for Anglers, Hunters, Trampers, Families, Tourists, Campers – basically anyone who enjoys outdoor adventures in the South Island.
