Coloane’s (and Macau’s) longest trail, the 8.1km Trilho de Coloane, begins in the mid-section of Estrada do Alto de Coloane and winds around the island. To get there, take bus 21A, which originates near the A-Ma Temple on Macau Peninsula, and get off at stop Estrata do Campo, then enter Estrata Militar across the road; after 600m, turn right. You can make a detour to Alto de Coloane (170m) to see the A-Ma Statue.
The shorter Coloane Northeast Trail (Trilho Nordeste de Coloane), near Ká Hó, runs for 3km. Other trails that offer good hiking include the 1.5km-long Altinho de Ká Hó Trail which loops around Ká Hó Reservoir (九澳水庫) to the northwest of Hác Sá beach, and the 1.5km-long Circuito da Barragem de Hác Sá which snakes around Hác Sá Reservoir.
