Alum Hollow – 13800 South Shawdee Road, Huntsville, AL 35803
(Located about .5 mile past the entrance to Madison County Nature Trail)
- Alum Hollow Trail: (1 mile) The main trail in the Green Mountain network, follows the bluff line. This trail is easily navigable with the exception of a steep downhill climb at the end leading to the final destination – Alum Falls and around the corner Alum Cave – a rock overhang that the Native Americans used for shelter.
- East Plateau Trail & West Plateau Trail: (East Plateau 0.6 mi. / West Plateau 0.4 mi.) Both are primarily flat with gentle hills. They begin and end on Alum Hollow Trail.
- Stonefly Trail: (0.6 miles) Meandering down the mountain, this trail exits Land Trust property and connects to Buzzard Falls Trail, which leads to a nearby subdivision – Oak Bluff on Green Mountain.
- Talus Trail: (.6 miles) This trail connects directly to Alum Hollow Trail. Talus meaning “a sloping mass of rock fragments” was a very appropriate name for this trail. It is very rocky and currently dead ends but will eventually continue to the bottom of the hollow.
- Ranger Trail: (1.2 mile) Rated difficult for its rocky terrain and incline, Ranger Trail takes its name from the remnants of a Ranger Truck abandoned alongside it. The trail ventures downhill then loops back uphill to Alum Cave and the waterfall. Hikers are welcome to explore. The trail is passable but unfinished so please use caution.
- Talus Connector: (.3 miles) Connects the Three Sisters Loop to Talus.
- Oak Bluff Trail: (.6 miles) Connects the Oak Bluff subdivision to the Stonefly trail. This was an existing trail when the Land Trust acquired the property.
