Time Out says
Tai Tam’s Turtle Cove is a dinky golden wonder bordered by lush greenery. Pale skinned peeps beware, there’s not much shade but it’s a peaceful spot frequented mainly by locals. Bring your own drinks and snacks since there’re no stalls.
How to get to Turtle Cove:
MTR to Sai Wan Ho, exit A, then bus 14. Get off just after the Tai Tam Reservoir stop and take the steps down to the beach.
