Frequently Asked Questions
Is the gorge trail difficult?
The Hubbard River Gorge trail is moderate — rocky and rooty with some steep sections near the waterfalls. Wear sturdy shoes and use caution near the wet rocks. The hemlock-shaded gorge is stunning in all seasons.
What is the hemlock woolly adelgid?
The hemlock woolly adelgid (HWA) is a tiny invasive insect from East Asia that feeds on hemlock needles — killing trees within 4-10 years. Since arriving in Virginia in the 1950s, HWA has spread north, devastating hemlock forests across the eastern US. In Massachusetts, many hemlock groves are dying. Scientists are releasing predatory beetles from Asia as biological control.
