Fortification Hill is a 4 mile lightly trafficked out and back trail located near Willow Beach, AZ that features a lake and is rated as difficult. The trail is primarily used for hiking and trail running and is accessible from September until May. Dogs are also able to use this trail.
This is a little-known trail that climbs to the summit of Fortification Hill, an extinct volcano gone mesa, which overlooks Lake Mead and the Hoover Damn. Most of the trail is fairly easy, although there is a stretch of about 20 feet up the Basalt headwall that offers some slightly unstable hiking. To make matters worse, there seems to be a wind funnel right at this junction. A walking stick would be highly recommended. 4 miles round-trip.
This is a fun hike to one of the biggest little-known landmarks in the Boulder City Area. You need to take the Kingman Wash Access Road, which is the dirt road that you'll find at the first exit past Hoover Dam. Follow the dirt road until it comes to the boat launch area. You'll find some port-a-potties here. Make a right. The dirt road narrows and becomes a little rougher. I would recommend a vehicle with some ground clearance, although I have seen people driving on the road with sedans.
