Lower Falls is the furthest downstream of the large drops on the Gooseberry River. I saw pictures to suggest there might be smaller falls further downstream, which would not surprise me. The river drops numerous times along its journey to Lake Superior.
Lower Falls has two different parts that could even be considered two different falls separated by rock. The photo here shows what I believe is the right side, though I might be wrong about that. Other pictures show different viewpoints. Whatever viewpoint this is at, the falls at Gooseberry Falls State Park are really great and VERY easily accessible.
1) From MN-61, turn into the entrance for Gooseberry Falls State Park.
2) Head to the parking area for the visitor’s center, where you will be able to easily access the falls. There does not appear to be a fee to enter this park.
3) Follow the trail down to the first group of falls, which includes Lower Falls.
