No trip to Cali is complete without visiting Cerro de las Tres Cruces, three crosses that tower over the city. The views here are spectacular. It's a hefty two- to three-hour walk (round trip) from Granada heading northwest – bring plenty of water. Security is an issue on the trail – especially on weekdays when it's more or less empty – so travel in a group and don't take any valuables. There are several trailheads; the easiest one to find is near Av 10 Oeste at Calle 12N.
Marker Km18 lies 18km west of the city. There are numerous bars and restaurants here. At 1800m it's pleasantly cool, and the nearby cloud forest is an Important Bird Area (IBA) with high biodiversity. The walk from here to the small town of Dapa (four hours) – off the Cali–Yumbo road – is a pleasant stroll. There are numerous crossroads – always take the left-hand fork.
There are regular bus services to Km18 from the bus terminal (COP$2500, 45 minutes). Buses and jeeps service Dapa every half hour (COP$4000, 30 minutes) from Sameco in the north of Cali.
