Sweet little loop! Gradual climb with some fun descent and nice views of Scottsdale and Phoenix. Watch out for Cacti and drink lots of water, it's very exposed and the Sun is relentless.
I think this is a fairly new trail so please be kind to hikers, so we can keep this trail open to bikes.
124th street and Via Linda. Take Via Linda to 124th street and turn left, go past Cactus and the trail head is in Lost Dog Trail Park on your right.
