I like to walk means you like to do something... it is walking. Here, the walk is a verb I like walking means you like something.... it is walking. Here, it is a noun. I like "to walk" or "walking" ?, I like to walk is more appropriate. Bana, I like walking is correct in grammar. But, walking is a noun, it means walking is the habit, "to walk" is an incomplete sentence, it implies an act that you want to do.

I'm not English native, but I'll tell u abt what I know grammatically. we say: I like walking, as when we say for example: I love going to walk on the beach everyday. - They both( like/ love ) come after them (standerd) verb+ing. - When we use: I'd like after it comes +to+(standerd) verb

You should say"I like to walk". here is the fixed structure as "like+to+verb"

There is NO difference. Because the verb 'like' is specifical - you can use in both before gerund and infinitive form. Both version are correct and have same meaning. Other verbs with which you can use gerrund and infinitive are here: - begin,start, continue; - love,prefer; - hate,can't stand, can't bear;

i think that wasn't have absolutly answer it decide in which enviroment u use this sentence for example if you tell somebody that your hobby u could say ' i like walking' if u tell somebody that how u go to work u could say ' i don't like to take bus ,i like to walk,it's good for my health. :)
