The short answer
Kalyani, the giant eucalyptus: what visitors should know first
Yes, as a short stop. Kalyani is one tree, so go for its sheer size and the cool shade under it, not for a long visit. It sits inside the Environment Park compound, so pair it with the park and the Horsley bungalow in one easy loop.
History and context
The story behind Kalyani, the giant eucalyptus
The hill takes its English name from W.D. Horsley, a British collector who built a house here around 1870. Kalyani is said to date from roughly that period, though reported ages vary from about 150 to over 160 years.

Why it matters
Why Kalyani, the giant eucalyptus is worth your time
Eucalyptus is not native to India. Species were widely planted on the southern hills in the 19th and 20th centuries, and parts of Horsley Hills' original vegetation have since been replaced by eucalyptus stands. Kalyani is the survivor that people actually come to see, and it stands next to the building associated with W.D. Horsley, the British collector after whom the hill is named.
That makes the tree a small piece of living colonial-era history, and also a prompt to notice the local ecology around you: the hill was once forest with sambar, wild boar and sloth bear, and it still holds a long bird list.

How to experience it
Kalyani is hard to miss once you enter the compound, but the scale only registers when you stand at its base and look up. Sources differ on its exact size: one Wikipedia-based description gives about 40 m in height with a girth of 4.7 m, another source puts it nearer 35 m. Treat these as approximate, and judge for yourself.
Walk once around the trunk, then step back to the edge of the lawn to take it in. Eucalyptus bark peels in long strips, so the trunk looks pale and patchy, and the canopy sits high enough that the ground beneath stays open and breezy. Early morning is the best time, before school groups and weekend crowds arrive.
From here it is a short walk to the old Horsley bungalow and the park's small zoo area, so you can fold all three into one unhurried hour.
