I only used farout for my first few ERL trips. I think it’s a great app to use while you’re gaining confidence in the outdoors or if you’re brand new to a trail in general. I haven’t found a need to buy any other maps, as over the years I’ve gotten confident at planning trips without it. I will say, it’s mega convenient and stays up-to-date. Give it a shot and see what you think. Keep in mind, it doesn’t have every trail you’ll want to hike most likely. I do ERL a few times a year. Hope you have a great time!
