These are some points you could use:
-when did you go? You should be detailed: when, how, how long did you stay there?
-what did you do? Picking strawberries. Visted a noney, butterfly farm. Took lots of pictures
-how was the place? beautiful, breathtaking view, cold, breezy
-did you have fun? express how you felt: happy, tired/exhausted
-mention that this was a great trip, you hope to visit that place again soon.
I HOPE THIS HELPS! :)
