Actually, it doesn't matter whether there is signal in the national park or not. There are only a few roads in the park. The tourist center of the park has free maps. Just follow the map and you won't get lost. ?

Be safe and get an offline map, it's more reliable. I use Maps.me.
Yes, you can do it if you check the map before traveling. But it's different for those who don't have a sense of direction and are always worried.
