Boat Field Trip to Tolo Channel and Double Haven North East New Territories

Why We Recommend it

Geologist/geophysicist Jason Ali leads a boat geological and geomorphological excursion to the beautiful and inaccessible northeastern coast and islands of Hong Kong.


Participants travel along the Tolo Channel, a flooded river valley, a major extinct fault line that bisects the HKSAR. The trip stops at Lai Chi Chong to examine Jurassic sedimentary and volcanic rocks along the wave-cut platform. Participants will get the chance to circumnavigate the landmass to view dipping sedimentary rocks that were originally formed in a desert setting, before cutting across to Bluff Head to discover the territory’s oldest – at 360 million years – rocks exposed in a vertical dipping succession.

The boat then sails to the western end of Double Island to view supra-tidal platforms and the Yan Chau Tong Marine Park, the “Sombrero Islands” while passing through Double Haven, before stopping at Ap Chau, a sedimentary island made up of angular rocks.  The island is also home to Hong Kong’s largest natural sea arch.

The excursion then passes by Kat O to view its steep rugged coastline and sea caves. Another highlight of the trip is the Governor’s Beach on Double Island, a stunning cove reserved for the Governor’s Yacht until the 1970s. Participants have the option of joining the trip at Central and catching our bus to Ma Liu Shui or joining the trip at Ma Liu Shui public ferry pier.


Please note that the assembly point is Central.
