Day trips from Kota Kinabalu

I went to Semporna and Kota Kinabalu last year and it was so incredible that I’m already planning to go back this year .

In KK, I did Mengalum Island, Sapi Island and Manukan Island (or maybe Mamutik Island, can’t remember exactly ).

Any recommendations for other day trips? I’m mainly into paradise beaches and not really into trekking.

Thanks in advance.
