What runners say about Green Mountain Nature Preserve (Alum Hollow Trailhead)
“It was the perfect day hike, not too hard and the trail was well maintained.”
“Other than our little sidetrack excursion, it is absolutely beautiful and Alum cave has nothing on the shelter that you see right before you get to the Grotto.”
“The trail can be challenging in a few places if you are unsure about your balance but overall a long hike mostly in the shade.”
“Most trails are easy to stay on but some are less frequently used and therefore not clearly marked which makes it easy to get off of them.”
“Peaceful and serene lake view and walking trail, be careful walking down to the lake many exposed tree roots.”
Nice, clean hike. Ended up on the ranger trail, would recommend trekking poles for it.
Trails are a lot of fun and easy. Ranger trail was moderate to hard. Would recommend using trekking poles on the decent. There are plenty of waterfalls and scenic views. Also. You have to walk down to the Ford ranger and look at it. It is right next to the cave.
We hiked the Alum Hollow Trail at the Green Mountain Nature Preserve with our two dogs. It was a great trail and was pretty easy. We are glad we wore our hiking boots as the trail had some rocky terrain. The trail provided a beautiful view of the waterfall and had a few water streams to view on the hike as well.
Great trails, you can choose to stick to the easy flatter trails or venture down into the valley. There are multiple streams with picturesque waterfalls so don't forget your camera!!! We did a quick hike for our first time, but we plan on returning soon to try some of the more difficult trails.
