Trekking has emerged as a popular adventure sport for Mumbai's outdoors-happy folk, and new locations spring up every calendar year.

A trekking group has decided to tweak things and organise a moderately difficult trek to a secret location that is home to one of the state's northernmost forts nestled in the forests near Palghar. A two-ho­ur trek will take you to the top of the fort, which offers a breathtaking view.
