Very useful tool! – Maplets – The Offline Maps App Review

Simple. Download the parks you plan to visit. You now have the park map on your phone. While you’re there, GPS will locate your current location on the map with a blue dot. Brilliant. Just used it in Lassen NP where cell service is virtually non existent. I was able to keep track of my location on roads and trails while in the park.
