The Herzliya Park offers a good opportunity to bike, jog or walk.
There are separate lanes and paths for joggers and bikers, so that they don't run into families with children, strollers, pets etc.
The environment is varied, part of the paths are in nature, besides the seasonal pond which (in winter) is rich with birds and amphibians, and part of the paths course near lawns and flowerbeds.
You can walk the entire length of Herzliya's coastline: It's 5.9 km one way.
Starting in the Tzuk (cliff) Beach in the south, the first 2.4 km segment will bring you to the Acadia Beach. On the way you will pass the built-up marina, where you can add an extra 2.16 km to your route by walking along the pier to the end and back.
The route continues from Acadia Beach to Zvulun Beach (1.2 km), then further north to the Sharon Beach (0.6 km), to the Nof Yam (Sidna Ali) Beach (1.2 km) and to the ancient port of Apollonia (0.5 km). The route is signposted by the Herzliya Municipality.
One of the popular sports in Israel is the Jetskis, and no wonder, its really fun.. but okay i admit, its less fin when you are Not the droiver but the one who sits behined...
However you'll see them especially in the marian area beaches as there's one beach that is dedicated for the Jetski's riders, in order to prevent any accidents with people who come to swim.
