Section 10 is the longest section of the MacLehose Trail. Continuing off Section 9, the trail follows the Tai Lam Forest Track towards Kat Hing Bridge, a historically important bridge connecting Yuen Long and Tsuen Wan before the completion of Castle Peak Road. The MacLehose Trail originally diverged from the concrete road here to follow the northern shore of the Tai Lam Chung Reservoir, but was permanently diverted in October 2009 — the trail now continues along the road, passing through the sweet gum woods of Tai Tong — a seasonally popular destination known for its red autumn leaves. The concrete road eventually gives way to an undulating mountain path, along which a Kwan Tai Temple known for its statue of a red horse is situated. Further along the trail is a crossroads, where a prominent set of stairs leads towards the Reservoir Islands Viewpoint. The viewpoint provides expansive views over the islands of the Tai Lam Chung Reservoir, which gave the reservoir its nickname of "Thousand Island Lake". The main trail then re-joins a concrete road and the old lakeside path near distance post M186. After reaching a car barrier, the trail follows a flat catchwater westwards along the contours of the mountain. This portion stretches for more than six kilometres, with average views over So Kwun Wat and the Gold Coast. Towards the end of the Section, Tuen Mun Town comes into view. The endpoint of the full MacLehose Trail is under a Light Rail overpass near Pui To stop, at the end of a descent from the catchwater — an example of the contrasts between Hong Kong's countryside and urban areas.
