Note that we went in late March. Though the temperature was mild, is was WINDY. We first did the touristy thing and crossed the Mile-high bridge (in gusts of 50 mph), but we really came for the hiking. We started on the well-marked Grandfather trail on the north side of the parking area. The first part was pretty easy going, and luckily sheltered from the wind. At the junction with the Underwood Trail, we decided to bear left and take the 'protected' route. This trail is mainly in the woods and involves a pretty strenous climb up a set of stone steps...some natural and some engineered. At the top of the climb in the only ladder on this trail, not too intimidating. At MacRae Gap, we kept right and climbed up to MacRae Peak. The actual peak involves a ladder climb onto the actual summit rock...an adventure in the high winds. But the 360 view was worth it. We headed back to the parking area on Gradfather trail, rather than back-tracking on Underwood. If it's windy, you'll feel the full force on this 'unprotected' route, much following the rocky ridgeline on the way down. For the faint-at-heart the series of ladders down is a bit intimidating, but once down it's fairly easy back to the start. If we'd known the details of the ladders, we'd probably do this loop counter-clockwise. All in all, it's a great little hike. Make sure you grab a trail map at the entrance.
