Introduction
As I don't want to steal someone's work, I give you a link where you can find a map to help you locate the treasures.

Access to Savannah:Savannah is unlocked after completing 18 offerings and the Petrified Giant IV ? quest (completing the fire mine). The player must also break the giant boulder next to Paul's house. After providing 18 offerings, a cutscene will play where the Goddess of Flowers will open a bridge to the savannah.
How to acquire maps?There are two machines in Savannah, where you can donate crops and get rewards including decorations and maps. You can get maximally 10 rewards a day, 5 from each machine, which will cost you up to 10 000 coins worth of crops. The excess amount stays for the future donations.
Fenn's Secret Map 1
Going down from the Cave of Memories and then to the left.
It is not where the cursor is, it should be right under the tree.
Fenn's Secret Map 2
Going to the right from the ostriches go over the river and then go up and turn left, just like on the map.
Fenn's Secret Map 3
Fenn's Secret Map 4
It is almost right where you jump out of the flower. Just go slightly down and then turn left.
Fenn's Secret Map 5
Going down from the third secret map location turn left and go over the bridge, the treasure is between 2 giant mushrooms.
Fenn's Secret Map 6
This one is probably the easiest. Going left from the ostriches and then up you will see a giant mouth opened and treasure under it.
Cave Of Memories
Cave becomes available after completing all the offerings at the Lake Temple's advanced altar.
Rest of the maps can be only found in Cave of Memories in treasure rooms that look like this:
They are extremely rare and I haven't found a single map yet (so below I provide you low quality maps from wiki). If you only want maps from the cave, I suggest you take great amount of ropes and explosives to skip levels as fast as you possibly can just to look for the treasure rooms.
NoteFollowing locations are not confirmed and are only my guesses of where the treasure could be. If someone is willing to share the screenshots and confirm the locations, I'd be more than grateful.
Fenn's Secret Map 7
It is before you teleport to the bottom of the savannah, go along the left side and match the location with screenshot above.
Note: Good thing is I found this one, bad thing is I found another copy within 5 minutes -,-
Fenn's Secret Map 8
Treasure is on the left of buffaloes.
Fenn's Secret Map 9
After teleporting to the bottom of Savannah, just go slightly to the left and it should be on the right side of Treasure Bubble.
Fenn's Secret Map 10
If you look at the map, go up from ostriches and stop by the tree where the treausure should be :D
Postscript
As previously said, some images are low quality and locations (7-10) are not confirmed. If anyone is willing to help and complete this guide, feel free to send me screenshots and rest of the information, I'd be more than grateful. Hope I helped you with this guide and wish you pleasent and joyful gameplay! :)
