When you register for City Hike, we'll email you a link to get our exclusive app.

Our City Hike app will help you learn more about Sierra Club and national environmental issues as you’re hiking. If you're registered for the Boston or Los Angeles City Hike, we will also provide you with a custom-mapped route via All Trails and several points of interest along the way.
