Its a lot of fun and it does take practice to build your confidence. Take a look on a map and pick a point you want to Navigate to and then get to it. See how close you can come to a reliable landmark. Rivers can change course but a large bend or the point of land surrounding it should be easy enough to find. Triangulation will become a really useful skill..Taking a bearing off two points and figuring out exactly where you are. Knowing your approximate length of stride and how long it takes you to walk a mile in uncongested terrain is also useful..I have been walking for 6 minutes which means I have probably covered x number of feet..knowing there is 5280ft in a mile or some other known number will help you estimate your progress from or to a destination..(the map is not the territory) You can break down your location into 10m grid points if your maps scale is sufficiently detailed..Literally so much fun to be had. Its a skill and having the correctly scaled map of the area will help you to plan and have a reasonable estimation of your time of travel depending on the terrain. Lots of fun. Be safe out there and be prepared. The better you plan the easier it will be.
