As I mentioned in the text for another picture from Aruba it is also possible to go for a horseback riding there. We went to the place called Rancho Loco where we picked up our horses with the help of very friendly staff. I was so fortunate that with my 183 cm height the only wise choice was the biggest horse they had, named Titan. My second time in the saddle in my life and directly on the horseback of massive Titan 
Well, anyway I survived and also I was able to take my camera out in the saddle when I made a bond with my horse
So, the track took us through the Arikok national park that looks like proper desert or mars surface onto the other side of the island with very rough sea and amazing rock formations. One of them created big hole that is filled with sea water and its called natural pool and people can go there to swim as it is separated from the rough sea and quite secure.
Trip was quite long. It took us about 5 hours and we came back when it was already completely dark.
If I will feel for it, I will create whole trip thread in local stories with more pictures.
