Mount Agad-Agad is the easy hill hike above Iligan, rising to about 490 metres and giving broad views back over the city, Iligan Bay, and the hills behind town. It is not a wilderness trek, but it adds a dry-land viewpoint to a city otherwise defined by water.
Start early to avoid the heat. If you only have one day, the waterfalls come first; add Agad-Agad if you want a sunset view or a short climb.
