The weekend

Today we were in a new zone for aclimb, it's near of my house. When we arrived there were a lot of people, because it's a very sunny place and in the other place, the wind was very strong. Anyway, we enjoyed ourselves and are thinking of returning again, perhaps next Friday or Saturday. 

Tomorrow we'll go to the forest to ride our mountainbikes. I will have wake up early, and I hate that.

The Weekend

Today we were in a new place for a climb. This place is near my house. When we arrived there were a lot of people because it is a very sunny place and a place where the wind is very strong. We enjoyed ourselves and we are thinking of return again, perhaps next Friday or Saturday.

Tomorrow we'll go to the forest play with our mountainbikes. I don't like it because I have to wake up soon, and I hate it.

Note: In the last sentence I am not sure what you are trying to say. Are you saying that this was all a dream and now it's time to wake up?

En la última frase no estoy seguro de lo que está tratando de decir. ¿Estás diciendo que todo esto era un sueño y ahora es el momento de despertar?

today we were in a new zone for to climb ,this place is near of my house...

Basic corrections:

Capitalize "today."

"Zone" is just not the right word here. Use "area" or "place."

"Near of my house" should be "near to my house."

Some possibilities--all natural phrasing in English.

Today we were in a new place to climb. This place is near my house.

Today we went climbing in a new place near my house.

Today we went climbing somewhere new, in a place near my house.

Today we tried out a new climbing area, near my house.

Today we tried a new climb, in a place near my house.

You have "run-on sentences." When you are not sure, put each thought in a new sentence--use periods (.) instead of commas (,).
