The beach

Today I would like to write about the last Sunday. We had been planned (or we had been planning) a trip to a certain beach in the southwest of Ireland and we were really excited. We had chosen the Inch beach because it was in a list of the best Irish beaches.
The journey was as usual in Ireland, that is, by narrow routes and suffering the rain from time to time. My children don’t like this kind of journey and they usually make get (or become) dizzy. Curiously this time they didn’t make get (or become) sick which is good for the car upholstery. We needed two hours to cover barely one hundred kilometres.
Once there we were delighted with the place. The background was amazing, the sand fine and the beach huge. All seemed perfect if it weren’t for the wind and the temperature. We were freezing and we couldn’t believe that some people were swimming in such cold water. We know the beaches of the north of Spain but that was too much for us.
We were inside de the car looking at the landscape for more than one an hour. Then I suggested going to a closed village close-by (or a nearby village) to take have a coffee. Before that we were playing football to keep warm. Fortunately the village was very nice and had plenty of shops to glance at browse for (or look at) souvenirs and so one on.
We were thinking to come just getting ready to go back home when I wrote in a panel read on a sign that there were was a climbing area over there. It was a pity! I would have liked to see have seen it.

Very well written Alvarez. I remember swimming in the sea in Scotland when I was young, so I know how cold that feels!

My corrections are in red and my suggestions to sound more natural are in blue/grey.

Notes: 

We had been planned a trip : You can say either "We had planned a trip" or "We had been planning a trip". Either version is OK in this context.

they usually make get dizzy : If you want to use the verb "make", you would need to say "this kind of journey makes them dizzy". It's the same with your following sentence, where you could have said "Curiously this time it (the journey) didn’t make them sick".

more than one hour : This is grammatically correct but when you are talking about only one hour, one minute, etc., it's more common to say "more than an hour" or "only for a minute".

the village was very nice and had plenty of shops : You could also have said "the village was very nice and there were plenty of shops" or "the village was very nice with plenty of shops"

The beach

Today I would like to write about the last Sunday. We had been planned a trip to a certain beach in the southwest of Ireland and we were really excited. We had chosen the Inch beach because it was in a list of the best Irish beaches.

The journey was as usual in Ireland, that is, by narrow routes and suffering the rain from time to time. My children don’t like this kind of journey and they usually feel dizzy. Curiously ((<--"Oddly" or "However" work better here)), this time they didn’t become sick, which is good for the car upholstery. We needed two hours to cover barely one hundred kilometres.

Once there, we were delighted in the place. The background was amazing, the sand fine and the beach huge. All seemed perfect if it weren’t for the wind and the temperature. We were freezing and we couldn’t believe that some people were swimming in such cold water. We know the beaches of the north of Spain but that was too much for us.

We were inside the car looking at the landscape for more than one hour. Then I suggested going to a close village to have/drink a coffee. Before that, we were playing football to keep warm. Fortunately the village was very nice and had plenty of shops to glance at souvenirs and so one.

We were considering to come back home when I wrote in a panel that there were a climbing area over there. ((This does not make sense. I'm not sure what you are trying to say.)) It was a pity! I would have liked to see it.

Excellent job!
