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

Leader: Dr Jason Ali
Saturday, 26 Nov 2016

We are delighted to welcome Dr Jason Ali again to lead a boat geological and geomorphological excursion to the beautiful and inaccessible northeastern coast and islands of Hong Kong.  This is our most popular field trip and an early reply is recommended.

The boat is to travel along the Tolo Channel, a flooded river valley that follows a major northeasterly fault line.  The trip first stops at Lai Chi Chong to examine Jurassic sedimentary and volcanic rocks along the shoreline.  Then the boat goes to Chek Chau (Port Island) to view the dipping sedimentary rocks that were originally formed in a desert setting, and then the near-vertical delta sediments at Bluff Head – the oldest rocks (at around 360 million years) in Hong Kong.   

The boat then makes a circuit around Double Island to view "supratidal platforms" and the Yan Chau Tong Marine Park.  Arriving at Double Haven we see the “sombrero islands”, before stopping at Ap Chau, a sedimentary island made up of large angular blocks of rock and most importantly of all, Hong Kong's giant spectacular natural arch which we shall walk through. 

The excursion then visits Kat O to view its steep rugged coastline and sea caves.  We then view Governor's Beach on Double Island, a stunning cove reserved for the Governor's Yacht until the 1970s.
