Also known as: Lantau South
Coastal Chi Ma Wan peninsula on south Lantau - sea views, secluded bays and forest; regarded as one of HK's best (and hardest) MTB loops

Whether everyone in your group gets a day at Chi Ma Wan - the grades on offer, the named zones, and how mixed abilities split up.
Blue to black diamond (AFCD/HKMBA); Trailforks notes blue overall if you dismount the technical sections
Beginners/less confident riders should avoid or turn back at the first technical sections; advanced riders add the ~3-mile technical extension. No lift - self-powered loop from Mui Wo.
Best for confident intermediate-plus riders; the technical rock and hike-a-bike make it a poor fit for beginners. Cohesive group of similar skill recommended.
Rocky technical singletrack, stairs, rock gardens and short steep dirt pitches
Very rocky with technical drops, stairs and rock gardens; named features like 'the fridge' (rock drop with off-camber landing) and 'the steps from hell'. At least ~4 sections require dismount; extension adds tight rock traverses and big step-ups/downs.
Single undulating trail with no turn-offs (follows Lantau Trail Section 12 corridor); AFCD designated-trail signage. Easy to follow once on it.
Quieter and more remote than NT trails; solitude likely midweek
Rideable year-round (subtropical, no snow); wet/summer conditions greatly increase risk
Autumn to spring (Oct-Apr) - dry and cooler; rock is treacherous when wet
Slick rock and stairs when wet; summer heat/humidity and typhoon rain; exposed coastal sections
No fee; ride AFCD-designated trail only (off-designated riding prohibited)
Permits and operators change - confirm before booking.
From Mui Wo ferry pier, ~400 m along the coastal road then steps up to Lantau Trail Section 12; ferry from Central to Mui Wo
No lift/shuttle; access by ferry to Mui Wo then self-ride. Buses serve south Lantau.
Carry plenty of water and repair kit - remote loop with no resupply; capable trail/enduro bike and protective gear advised. Patchy coverage in remote sections possible (est).
Amenities at Mui Wo (shops, ferry pier, McDonald's); minimal on the loop itself
Hong Kong Mountain Bike Association (HKMBA); Mui Wo / Lantau bike hubs; AFCD country-park management
Committing, remote and technical - the loop has no turn-offs; several forced dismounts. Very slippery when wet; carry water and tell someone your plan.
None required, but ride with partners given remoteness and technicality
Limited bail-out points on the single loop; roads at Chi Ma Wan/Pui O for exit. HK emergency services (999).
