This property was apparently recently purchased and theres a huge gate across the trailhead. Luckily if you know the right people the owners fine with responsible hikers. Definitely worth the hike out and Vandalism is a huge thing at this trail. take any valuables out of your car and it recommend leaving it unlocked if you don't want to replace broken windows. While we were there I left my car unlocked and took everything valuable out, someone still got in and stole my car charger and a letter I had written for my grandfather but not yet posted. My friends car was locked and they broke the window and ransacked his truck.

Very well traversed with good coverage. Downfall of the coverage is the amount of spiders haha. We checked out the caves a little bit but my group got skittish so we continued to the cliffs. The water and scenery was incredible. We dive some cliff jumping too because the water is deep. On our way back, my friend and I went back into the caves. The water is just out of sight from the opening of the cave. There were some people down there and they showed us the back part of the cave and we got the rest of our group to come in too! Definitely bring flash lights. This hike was absolutely incredible and we will definitely go back again.

DON'T DO MT. LAM LAM TRAIL IF YOU ARE JUST VISITING. I just recently did this hike a few days ago when I was visiting the island for the week. If you are looking for a view the beginning of this trail is great but instead of following the trail to the summit of Mt. Lam Lam take the more obvious path to the right towards the crosses. This has a beautiful view and has much more bang for your buck. This portion took me about 30 min to get to the top. As for hiking to the summit of Mt. Lam Lam. Only do this is you want to say you did it. There isn't much of a view, just a flag and some "jungle/rainforest" area that is neat to see. With that being said be ready for an overgrown path. I would HIGHLY RECOMMEND pants and maybe long sleeves. I had shorts and a sports bra on and my legs got pretty scratched up and my stomach had a few scratches due to going through the overgrown vegetation. The vegetation can make it difficult to follow the trail sometimes (you get can get confused because it seems like it could be a possible pig trail) but just pay attention to the map. Honestly the way out was easier to follow (due to the markers) than the way in was. Long story short I felt like the summit was not worth anything more than just saying I did it. The cross summit was way more beautiful and you could see the whole island and is totally worth the hour hike.

Great hike from start to finish, one of my favorite hikes on Guam. Beautiful scenery especially once you start hiking down the ravine into the river leading to the falls.

It was more of accidental hike since we stumbled this trail while hiking Lower Sigua falls.

Nice hike but muddy at the beginning. I would not rate this hike as hard maybe moderate. I was expecting a harder hike it took me 2 1/2 hours round trip

We ended up getting lost after the waterfall. We were able to find our way out after having to make our own trail and meet up with the original trail. Would definitely do it again and go counterclockwise around the loop rather than clockwise. Overall, the hike was great.

Bring Pants! The trail should be rated as hard because of the height of the grass and at time expect it to be from knee to head height at the last part of the trail. At times you will he expecting to see a raptor as you push through it. If you continue off trail to the two concrete building at the top it is steep and the poles came in handy. As the last review says, go in and out the same trail.

Pretty well marked trail with great views. Hike past the caves to the cliffs, the view and sounds are breathtaking! I got a little off trail on the way back since there are so many false trails, but just look for the faint spray paint for the way out once you pass the caves.

Fun hike! Our first on Guam. It was a bit muddy and slick on a few rocky areas, but overall not bad. Lots of shade. Would definitely recommend a flashlight for the cave. I had my son in a hiking backpack and we did the hike in a little over an hour.

Great trail! A little muddy and very slippery in some places but we'll marked and challenging once you start descending to the falls. Bring bug spray if you plan on spending any time down by the falls.
