There is a very cool app for iOS that maps the sun location.
Very handy for star gazing and selecting camp sites. Knowing where the sun will rise and set can help a lot in selecting where to place the doorway. I found it also help in planning trips so I’d be familiar with where the sun would be during the trip so to have best light for paddling and photography.
These are a few of the camping sites I planed to visit on my “Kayak Expeditions”
