Globally, there are many places you can go. If you are going camping to test your skills, start easy and progressively go to tougher areas. Challenging areas will be where there is inclement weather, very humid or dry environments, locations where clean water is not readily available, and fishing and hunting will be difficult.
If you are looking to go to a location to survive, find the most optimal place and there are plenty on this planet. Find a location with plenty of vegetation but not overly humid, a location with less humidity than other areas but have ample locations to gather water, a place where fish and game are available, and temperature changes during the day isn’t drastic. Learning bushcraft skills is a must as eventually, all things electronic will fail.
