Excuse me if I'm in the wrong location, but this is as close to a HELP! sub forum I can see as a new guy.
Is there a camping/hiking/walking/backpacking section somewhere?
no..... but if you want specific help with handhelds, nuvis or other Garmin devices that are not covered here, then look over at this website forum... http://forums.gpsreview.net/categories
Or if it's specific to a type of activity, then google the name of that activity with the word "forums" IE "geocaching forums" or "hiking forums"
For whatever reason, Garmin or whatever is responsible for this site have not shown a desire to cover every Garmin device or interest. For the most part it's Garmin's "fitness" devices and some select others that also are sometimes used for fitness.
