Learn the basics of sheltering, including how to find a good spot to build your lean-to and what to do when you encounter a pack of wild animals.
Look for a location with a natural water source, preferably with a waterfall nearby. Make sure it's not on a slope that's prone to landslides or flash floods. Also, try to find a spot with a good view of the surrounding area, in case you need to make a quick escape.
Gather materials for your shelter.
Learn how to lean against trees for maximum protection.
When in doubt, always remember: shelter is not just about protection from the elements, it's also about psychological comfort. So, try to make your shelter as cozy as possible. Add some soft blankets, a few pillows, and a good book to read.
