This is a very beautiful marine reserve with craggy rock formations, sweeping coastal views and features, including unusual caves, the ‘Miss Willy’ whale skeleton, WWII military batteries and Hong Kong’s oldest lighthouse (see separate reviews). However, it is also an isolated spot and well off the beaten track. If you only have a few days in Hong Kong, then you will be too busy with other sights and this is too remote and too out of the way to include in an itinerary.
Entry is free but to get there, you need to walk in. The bus will drop you off at the large roundabout which is where your walk starts.
It is one of the easiest coastal trails and is a roughly 5 km gentle, downhill walk along Cape D'Aguilar Rd (the bad news is that you will have to walk back up again unless you are lucky enough to snag a taxi that has dropped someone else off).
It’s not terribly well sign-posted. You can generally follow other hikers but basically stick to the road until you get to the radio transmitters. At this point, you take the dirt path on your left and circle around behind the station where you can pick up the road again to head downhill. Towards the end of your walk, the road splits but there is a large, blue sign at this point directing you down to the reserve.
Make sure to take sunscreen, hats, water and food. The walk is quite exposed and if you go on a weekday, there are no opportunities to buy anything. You’ll also need good shoes because once you get to the reserve the rocks can be sharp and around the caves and water, it is quite slippery. The only public toilets that we saw were two porta-loos about 5 min into the walk.
Be aware, that despite the beautiful waters and the hot walk to get here, you can’t jump in for a swim because it's a marine reserve. Instead, we took a taxi later in the day to Shek O beach for lunch and a cooling swim ($46HKD).
GETTING THERE: It’s a long-ish but very straightforward trip from Central. A taxi or uber will take cut your travel time in half and can also save you some walking because it can take you part of the way down Cape D'Aguilar Rd. You should pay under $200HKD. We found public transport easy although it took about an hour. We caught the MTR to Shau Kei Wan. Exit A3 brought us right up at the bus bay and the #9 bus went right to the start of the walk. The only tricky part is to double-check that your bus stops at Cape D’Aguilar. Not all do. Some #9 buses go straight through to Shek O so don't get on unless the sign specifically says “via Cape D’Aguilar”.
