Hiker's trail towards Lake Titiwangsa. From here, you have to climb this grassy elevation to find the trail pictured below. Walk further until you lose this trail, then you find a major road - Jalan Tun Razak - just beside it.
A couple of blocks from the elevation, you see this unmarked white building. Head further until you reach Istana Bupaya.
Interiors of Istana Bupaya (above) and the gorgeous exteriors below landscaped with stairs , a pond and a garden (taman).
You can change lines (Ampang Line) at the other train station. But Titiwangsa line heads south back to Bukit Bintang, Berjaya Times Square through its stop at station Imbi, and KL Sentral at the southwest terminal.
