On one of our regular weekend trips from Abu Dhabi to see my sister and her family in Dubai, Feliks, and Albert - the cousins - decided to plant the cache in the park in the trunk of the palm. They planted a small green tube containing just a pencil and a logbook.
So the geocache is located in the park on Palm Jumeirah - everyone knows the palm, not much to add here. The park - Ittihad Park - is a wonderful place for the kids and adults to enjoy time away from noisy streets and with plenty of shade around. The cache is located in the shadow of the overhead monorail, running through the middle of the palm.
The location of the cache requires some stealth and when found and logged - please put it back in in the exact same way to avoid accidental grabs.
The picture below shows my son Feliks with the geocache just below hiding.

UPDATE: Original green tube cache was stolen and replaced it with a box.

UPDATE Apr 15 2022: New cache placed, this is a third one in short timespan. Please hide it well. New cache is again a plastic container with pencils, a sharpener and a purple logbook. Enjoy!
UPDATE May 25 2022: New box placed, someone stole the old one!
UPDATE Jan 14 2023: someone stole the box but Albert found the original green tube!!!
