Entering from Mulholland there are a couple of short hikes up Indian Rock to the highest point in the canyon with 360 degree views including the valley to the North. The alternative route follows the fire road round the rock and splits off towards the Western High Way or goes towards Clouds Rest and a choice of circuits.

...steep mountain-side hike with the best views of downtown Los Angeles. Several trails, some paved, some dirt, that will give you a good cardio workout...
