Gilbert Hill

Go in cooler daylight

Morning or late afternoon is better for the climb and for seeing the rock clearly.

Expect steps

Wear proper shoes because the approach is more climb than casual pavement walk.

Read the geology first

Knowing it is a rare basalt formation makes the visit much more interesting.

Respect the temple area

The top has devotional use, so keep behaviour quiet and appropriate.

Keep it with Andheri plans

It is best added when you are already around Andheri or Juhu, not as a cross-city detour.
