I want to taravel to a lot of countries- - Spain, Portutogal, Turkey, Japan, New-zealand, Indonesia and Thailand.

Mostly a few spelling errors here and the punctuation period at the end to indicate the sentence has finished.

One of the Countries where I most want to travel to recently is Bail ofin Indonesia recently.

Adding "the" between of and countries helps give the reader or listeners context, in this sentence it shows that Bali is part of the list of countries you have mentioned.
I have changed Bali of Indonesia to Bali in Indonesia, both are technically correct however using "in" is more common.

Because I was showed my IG algorithm aboutkeeps showing me there.

I have replaced "I was showed" with "keeps showing me" and moved it to the end.

But I have beenwas there a year ago.

"Was" is used here because you have indicated the time when you were there.

but when I showee my IG, there isare new places and things in Bail

"see" is used because you are receiving the video. IG is showing the video to you.

"Are" replaces "is" because Bali has multiple new places and things to see and do.

If i travel again there, Ithere again, I will enjoy more Beach clubs and try running whith some people who meetI have just met for the first time.

"I have just met" gives the context in a way that is more natural to english speakers. The way you wrote it is understandable but relies on implications.

And I wanna try other exercise - yoga, climbing, surfing

Adding "ing" changes it from a verb to a noun.
Climb - Climbing
Surf - Surfing

Which one where dDo you want to travel to other countryies?¶
Which one?

It sounded like you wanted to ask two questions here. I have set this sentence to ask firstly if they would like to travel assuming the answer is yes then I have followed it up asking the to choose one.

Which one where do you want to travel?

We don't need both Which one and where here, to use Which I would say something like, 'Which countries do you want to travel to?'

I want to taravel to a lot of countries- including Spain, Portutogal, Turkey, Japan, New-z Zealand, Indonesia and Thailand.

Some spelling mistakes, should write 'travel to', I would preference saying 'including' instead of using a dash here

ORecently, one of Cthe countries where I most want to travel is Bail ofto the most is Bali, in Indonesia recently.

Better to put recently first here. We say Bali 'in' Indonesia. Sounds more natural to say 'where I want to travel to the most'

Because I was showed my IG algorithmThis is because my IG algorithm showed me lots of posts about ithere.

but wWhen I show myee these posts on IG, there isare new places to see and things to do in Baili.

added some words and usage of 'show' not quite right

So I wannat to travel there again.

Added 'there'

If iI travel again there, Ithere again, I will enjoy more Beach clubs and try running whith some people who meetI met the first time.

capital I, there before 'again', usage of 'will' for future. Not sure if I got the meaning right, if you are saying you already met the people last time and you will run with them again next time.

And I wanna try other exercise -I also want to try other activities like yoga, climbing, and surfing.

Generally try not to start sentence with And.

Which one wherecountry do you want to travel to other country?

Same as title, we should use either 'where' or which, not both

I want to taravel to a lot of countries-Spain, Portutogal, Turkey, Japan, New-z Zealand, Indonesia and Thailand .¶
One of Cthe countries wherethat I most want to travel is Bail ofto recently is Bali, in Indonesia recently.

I corrected a few spelling mistakes and tried to improve the sentence's flow in terms of grammar and structure!

Because I was showed my IG algorithm about thershowed me some videos of the place.

Makes a little more sense. Sorry if I am changing too much.

But I have been... I was there a year ago.

The ellipsis "..." adds some personality to the sentence :)

but whenHowever, my IG show my IG,ed me that there isare new places to see and things to do in Bail li.¶
So, I wanna travel there again.

Great! The word 'wanna' is really good for adding personality and a casual tone, but be careful if you're using it in a formal conversation. Then, you should use: "So, I would like/love to travel there again".

And I also wanna try other exercise -s like: yoga, climbing, and surf ¶

By the way, Wwhich one wherecountry do you want to travel to other country?

I changed some more little mistakes! But I love the idea of this piece!

If iI travel again there, Ithere again, I will enjoy more Beach clubs and try running whith some people whoI meet for the first time.

OoOOo this is a nice idea!!

Which one wcountries do you want to travel to?¶
or you could say, Where do you want to travel to?

The second option doesn't specify countries, whereas the first does.

I want to taravel to a lot of countries-: Spain, Portutogal, Turkey, Japan, New-z Zealand, Indonesia and Thailand ¶
. One of Countrthe cities where I most want to travel is Bail ofli, Indonesia, recently.

Bali is a city, not a country.

Because I was showed my IG algorithm about thereshowed me those places.

bBut whenmy IG show my IG, there ised me new places and things in Bail ¶
Sli, so I wannat to travel again.

'Wanna' is more like slang or an informal way of saying 'want to'. It is typically used in colloquial English, but people also use it when typing because it sounds more casual and is easier to type.

But I have bewent there a year ago.

And I wanna try other exercises - yoga, climbing, and surf ¶
