Hall Mountain Marsh is one of the lakes sitting in Bear Brook State Park; a picturesque lake with lots of green colors around, from the water, the forest, and the aquatic plants that grow on the lake. The trail to the lake can be accessed by Podunk Road and can get muddy in some spots depending on the season. It is not a very popular trail, so you can have some quiet moments by the marsh. Bear Brook Lake Park charges a fee of $2/youth and $4/adult (2023).
