National Geographic has a section called Adventure Travel Guides and Photo Tips on their website, called Path to Adventure. There’s an interesting Adventurer’s Handbook with 36 crucial skills, nifty tips and “shameless” shortcuts, all designed to accelerate your learning.
The Adventurer’s Handbook is divided into 3 sections :
– survival basics
– outdoor tips
– expedition tips
All the tips are very short, typically only 1-2 paragraphs.
