From this pebbly coast, you can simply wade across the approximately chest-deep water or swim over to Green Egg Island’s little beach! The ground underwater is also pebbly and could be uneven, so wet shoes would be a good idea. Whichever route you decide to take, the hike in should take roughly an hour and a half.
It’s not too strenuous a journey, though there’s little shade on the paths leading up to and down from the peak. The offshoot trail you’ll need to take to get down to the water is also fairly narrow and steep in places, so do proceed with caution. Leaving would be a matter of retracing your steps, so allot roughly three hours for hiking in total.
An alternative would be to kayak to Green Egg Island instead; there is one kayak rental shop in the nearby Sheung Sze Wan Beach. It’s a simple matter of sailing eastward and hugging the coastline until you reach the island. Otherwise, Blue Sky Sports Club in Sai Kung offers half-day tours to and from the island, which even includes a meal, gear for rental, and a tour guide to make sure you don’t get lost.
