Using an Iphone as a hand held GPS for hiking remote ares

[Gjac]

I want to hike Paria canyon in AZ to the first Wave and understand there are no established trails or trail markers to follow which I guess is common for desert area type hikes. My question is has anyone used their I phone as a GPS and what kid of maps need to be downloaded first? Is there a database for BLM topo type maps showing waypoints for these type of hikes?

True satellite GPS use can be a huge battery drain, no?

Look into OnX Hunt. It is a subscription app that gives you boundaries as well as owner info if the land is private. I believe it was designed for hunting, but it would work well for what you need.

I have a topo map and I will photocopy the area we will be in. Yes GPS works - when there is a signal. I like having a hardcopy as a back up.
