No special access issues
Access to Ngan Wan is via a very steep and slightly sketchy access path that weaves down the hillside between rock outcrops and the massive landslide scar. This trail is reached from a dirt trail opposite Lamppost #39 on the Dragon Trail, which is about 250m along the trail from both Siu Sai Wan and Cape Collinson Rest Garden (you can get to this point using the 18M Green Minibus from Chai Wan MTR).
Extreme caution should be exercised on the approach, especially when carrying a bulky bouldering mat, as fall from the path would have very serious consequences.
