There isn't really a "correct" answer for this. The two words are pretty much synonyms.
(For non-native English speakers: "walking" implies a somewhat more casual effort while "hiking" is more of a "let's get some exercise" word. If you wore a backpack, you should probably say "hiking". Special clothing can matter also: If you wore boots (other than cowboy boots) and shorts, you were almost certainly "hiking" rather than "walking". If you wore cowboy boots and shorts, I can't help you because anyone who would wear that combination is either a Dallas Cowboys cheerleader or beyond help.)
