The Marcus landslide trail is amazing. It contains some of the most unusual rock formations in Arizona and you can hike up a prehistoric landslide for an incredible view of the valley. The hike starts off pretty flat, but you get a workout if you chose the extra mile loop up the landslide. Scottsdale does a great job with their signage and the trail is mostly wide with some area sneaking under rocks. The vies are crazy good and this is one of the more scenic hikes in the area.
