The “ladders” are really more like steep stairs, but they're made of logs linked with cables, which can sway a bit underfoot. Hand lines of cable or rope are hung over them, allowing the use of the arms to pull up and to balance. These features are maintained but perhaps not regularly, so beware of loose and slippery steps. The national park states that the trail contains 56 ladders and 783 steps in total.

There are some flatter spots at which to rest and glimpse views through the trees, but for the most part, it’s a full-on sweaty slog all the way to the summit. Bring plenty of water and food to stay fueled for the duration. Muddy conditions will exacerbate the difficulty, so it’s best to save this adventure for a drier day.

To find the start, park at the trailhead for Lower Sauma Ridge. From there, walk a short distance west along the road, and look for the small hiking sign. The trail begins with a rope and ladder to climb into the forest right away.

The Park Service recommends making a loop instead of backtracking, in order to avoid two-way traffic on the ladders. After reaching Alava’s summit and taking in the views, you’ll reverse only the uppermost ladders, then turn onto another trail. This one descends in a more traditional manner (no ladders) to Vatia Village along a different ridgeline. Near the bottom, it connects with a residential lane that leads to the coastal road. From there, you must walk a mile on the highway or catch a ride to get back to your car.
