If you come to Bali, love hiking and love views.. you can't miss this!!
Pro Tip: Best views and weather in the dry season! (Mid-March to Mid-November)

Not sure if there's an age requirement, but it's not the easiest hike for everyone, if you're able bodied you will be ok, just know it gets a bit rocky/rubbley as you gte to the top - not dangerous but your feet can slip a bit so just be conscious of getting firm steps. It takes about 3 hours to go up and 3 hours to go down!
