Located in the McDowell Sonoran Preserve, this loop trail is a good option for hikers looking to get a good overview of the area without having to hike too far. The trail starts at the Gateway access parking lot and follows a half-mile trail over a bridge to the junction of the Gateway Loop trail. From here you can choose which direction to hike. The loop hike leads up to Gateway Saddle where many prominent landmarks can be seen to include Thompson Peak, McDowell Peak, and Tom's Thumb. There are many intersecting and connecting trails along the route so pay close attention to trail markers.
