Gdor Reserve, Nature reserve in Sharon Plain, Israel.

Gdor Reserve is a coastal and marine nature reserve on the Mediterranean between Mikhmoret and the Givat Olga quarter of Hadera. Its coastal section, part of the Sharon Park, centres on a kurkar and hamra cliff that peaks at Tel Gdor, 33 m high, where the remains of a square structure stand. The marine reserve covers 844 dunams; the coastal reserve totals 752 dunams, of which 105 are declared.

Tel Gdor is the 33-metre kurkar and hamra cliff that forms the highest point of the coastal reserve, and a square structure's remains sit on its summit. The sources record the tell and its ruins as the site's archaeological feature; the reserve itself was approved as a nature reserve and national park in April 2009.

The bay north of Tel Gdor is called the "Chinese Bay", named after immigrants who reached Palestine in the late 1940s after two years in Shanghai and used to holiday there. The reserve's beach is also where sea turtles come ashore to lay eggs; rangers move the nests into a fenced enclosure to secure incubation.

A safety fence blocks vehicles from entering the reserve, and people may not stay inside it at night. Fishing is allowed only in designated spots. The beach is rocky, with rock tables at the foot of the kurkar cliff, so wear shoes that grip wet stone.

North of Tel Gdor lies the "Chinese Bay", a small cove named for Jewish immigrants who reached Palestine in the late 1940s after two years in Shanghai and used to holiday there. In March 2025 a study by the University of Exeter's Centre for Ecology, with an international team, listed Gdor beach among the five most microplastic-polluted beaches in the world.
