Hiking Mt. Lam Lam is a must when you are in Guam. It's about 20-30 min up to the top and then a quick descent down. The views are spectacular - truly divine beauty.
Mt. Lam Lam is the highest peak in Guam and also, the distance from the peak to the bottom of the nearby Mariana Trench is the greatest change in elevation on Earth over such a short distance, quite remarkable!
