This trail is known for its sustained and demanding climb, making it one of the more physically challenging hikes near Bengaluru. The approach passes through mango orchards before entering forest at the base of the hill. After crossing a solar-powered elephant fence, the trail climbs steeply over exposed rock using carved steps and metal railings. On sunny days, the exposed rock absorbs heat and radiates it back, while the metal railings can become hot to the touch. The gradient eases onto a broad rocky plateau where natural potholes retain rainwater after the monsoon. The route then passes the remains of fort walls before a final climb through a short stretch of vegetation leads to the summit. A small temple occupies the highest rock, while the surviving fortifications indicate the hill's historical significance.
The trail climbs the eastern side of the hill to the Perumal temple before continuing across the rocky summits beyond. The section up to the temple is straightforward and can be completed by most hikers, but the terrain becomes more exposed and requires greater care after the temple.
The Periyamalai trek is one of the most demanding day hikes within driving distance of Bengaluru, combining long forested climbs with steep granite monolith sections. The route begins behind the foothill temple on a flight of stone steps before entering a shaded forest trail that passes smaller shrines, including one with a perennial spring. As the climb progresses, the vegetation gradually gives way to exposed rock, culminating in a steep monolith ascent equipped with railings and a short ladder. Remnants of old fort walls near the summit indicate the hill's historical use as a hill fort. The trek ends at the Perumal Temple, which occupies the summit and overlooks the surrounding Krishnagiri hill ranges.
Ankushagiri is a hill fort on the Karnataka–Tamil Nadu border, with the trail leading through dry deciduous forest to the ruins of a little-known fort. The hike begins from a Perumal temple that attracts large numbers of pilgrims on Saturdays, when free prasadam (community meal) is often served in the afternoon. The climb passes granite slopes and rocky sections before reaching the hilltop, where remnants of fort walls, are scattered across the summit.
Musattu Malai follows an old pilgrimage route to a hilltop Vishnu temple on the middle peak of the Trimurti hill range near Varatanapalli. Higher up, the route climbs through rocky terrain and reaches a series of stone steps leading onto the upper slopes. Near the summit are a small sacred pond and mature champaca trees surrounding the stone-built Vishnu temple, which is believed to have existed in some form for centuries. The summit provides uninterrupted views of the surrounding Trimurti hills and the agricultural landscape of the Krishnagiri region.
