My Favorite Place.
I like to spend my time outdoors, when I have free time. <s>And</s> My favorite place is a wild forest. (I find that starting sentences with, "and" very uncommon in written English, at least in my dialect).<s>The place where</s> There ("The place where..." makes me wait for the Subject so I would suggest, "There" to start this sentence. This is because you already mentioned the place "a wild forest.") you seldom meet people and <s>where </s>you can be in harmony with nature and yourself. I feel myself freely and calmly in the forest (This sentence is grammatical but the meaning is probably not what you want. I would suggest, "I feel free and calm in the forest."). There is always a peaceful atmosphere which makes me think about natural and simple things.
I like how the wind rustles through the trees and whispers things to you <s>something </s> (generally the object like "things" or "something" would go before "to you/to me" here. Also, I would suggest "and whispers" as you cannot say "to whispers" with the "s"). I like <s>its </s>the fresh smell of pine trees and the smell of wet ground ("ground" is an interesting word that can't take the indefinite article "a" so here there is no article but "the" is possible in other situations) underfoot.
Why do I like it?
Because I spent all my childhood in the countryside and my family and I often went to our nearest forest (this sentence is grammatical but "to the nearest forest" sounds more natural. "Our" would be more for something that you own - "our house" or "our dog" etc.). There was a large forest <s>in which were</s> with wolves and elk (in general North American English the plural of "elk" is also "elk" but I understand some English dialects do use "elks"). We usually went far into the big forest and it took one hour (because "one" is singular you do not need to add "s" to "hour") to get to the spot with mushrooms and blueberries. <s>In such forest </s>There (just like earlier, "there" is the easiest word to use here since you already mentioned the location in the other sentence) we picked <s>up </s>f("to pick up" means "to lift" as in "to lift off of the ground" but "to pick" means "to collect") full baskets of mushrooms and after that we were tired and happy so we went back home. I liked walking through the woods and collecting (if "walking" has "ing" then the other verb here needs "ing" too) unusual leaves, sticks and wood mushrooms. I had a really big collection of wood mushrooms with different colors and shapes.
Sometimes I miss <s>about</s> that time because I used to live in the comfort city (I'm not sure what you mean here) and rarely being outdoors (this sentence needs edits but which edits depends on what you meant by "comfort city"). But if I have an opportunity then we try to leave the city to spend our weekend outdoors. After that you feel <s>yourself</s> really good and rested, full strength and so inspired.
