Thanks a lot!!　Articles are always difficult for me.....

I understand your point better that way. I would write it as “in our town, we go hiking on New Years Day.” You would only say “the hiking will take place” if it were a special event with a name. “The” is used for specific events, “a” is used for more general activities -“a hike” instead of “the hike.”

If I write " In our town, the hiking will take place at new year's day." Is it okay?

Well written:) a few comments: Generally, when talking about the height of something, we say “it is _____ meters tall.” On time: one and a half hours, not one hour half. Proper nouns don’t usually have articles before them. For example, we would say “Mt. Yakurai” instead of “the Mt. Yakurai.” Biggest error: Our town will be held New Year’s Day...” I wasn’t sure what you meant there, I guessed and wrote that your town goes hiking on New Year’s Day. I think the problem here is twofold: incorrect verb choice (to hold instead of to hike) and incorrect tense (should be present continuous -goes hiking, not future continuous -will be hiking). Hope this helps!
