You need to be an intermediate hiker for this guided tour of Lake Superior. Good fitness is required as well as the ability to walk on different types of terrain. The average day will vary between 7-9 miles (11-14km) of hiking and you will be gaining 2,000-3,000 ft (600-900m). Keep in mind that you’ll also be carrying a daypack filled with water and other things you’ll need throughout the day.
I did Timberline in 1995 and 2000 with my dad and 2018 and 2019 with my son and daughter. Look forward to doing more tours with my grandchildren (if I have them).
