Ponds, Meadows & Falls
From the South Shore Trailhead at Two Medicine Lake hike through forest and by ponds and in meadows with views of the mountains off and on (in particular Sinopah (the Blackfeet word was Sinopaki meaning "Fox Woman" for the Indian wife of Hugh Monroe (Rising Wolf - another mountain at Two Medicine), and daughter of Lone Walker (another mountain at Two Medicine), a powerful Blackfeet chief) and Painted Tepee).
This is usually a ranger-guided option too but only on certain days. Note that falls and drowning are two of the top human causes of death at Glacier National Park. Extra care must be taken around running water.
You also can take the boat to the other TH (Two Medicine Pass Trail) and come up from the Lake.
