Best beaches in Chiang Mai

Hello Expats in Chiang mai!

I wanted to ask your opinion if what is the best beaches in Chiangmai.
I already visited Bangkok, Phuket and Ko Phi Phi and I think Ko Phi Phi is the best
place it's like paradise for me much nicer than our Boracay in Philippines but I got curious coz most of the tourist I met in Thailand
hop to Chiang mai.
I wanted to discover Thailand more and wanted to go back there by summer.

Any suggestion from this community would be greatly appreciated.

Thank you
