Take a nice hike from Es Migjorn Gran to Platja de Binigaus. It is very lovely. You can find four caches on the way plus a bonus at the end and another cache in the cave Cova des Colom. Don't forget to write down the number in the lid of every cache to calculate the coordinates for the bonus cache.
You can park your car at the parking coordinates.
Did you collect all numbers from the lids of the four caches? Then you can now calculate the coordinates of the bonus cache:
Cache Nr. 1: bonus number = A
Cache Nr. 2: bonus number = B
Cache Nr. 3: bonus number = C
Cache Nr. 4: bonus number = D
N 39 55.(B-C)(A+C)(A+B-D), E 004 01.(B-D)(A+B)(C)
Have fun! BalHo
