Is it permissible to say the Adhan while walking on foot in the wilderness?

The Adhan is an act of worship to Allah, using specific pronouncements after the time for prayer has begun, to announce it. It is disliked for a resident to call the Adhan while walking, though it is still valid. As for the traveler, it is permissible for him to call the Adhan while walking or riding, though it is more befitting for him to dismount and call the Adhan while standing.
