The directions are accurate and the road was mostly fine. On road 2904 there are numerous big humps (for drainage?) and one rutted spot that might pose a problem for lower clearance vehicles. Probably not a big deal if you take it slow. Trailhead has a couple dispersed campsites but nothing else on road 2904.
The trail climbs steadily. The first mile has humps (not unlike road 2904!) from all the motorcycle action. The final mile or so is the steepest but the hike is so short you might not notice. At the saddle, going left isn't an option. The trail to the hiker summit goes to the right and faces a steep drop-off with lots of loose rocks.
Four fellas and a dog left shortly after we got to the top and we had it to ourselves while eating lunch and taking pictures. There were clear views of Rainier, St. Helens, Adams and Goat Rocks. We didn't see anyone else—hikers or bikers—going either direction on the trail. Didn't expect much wildlife, but there were two garter snakes and a tiny frog on the trail. Across the saddle on the higher peak was a goat just sitting and watching us. No goat poop sightings so they must not come down often.
