I took Forest Service road 4109 up to the Silver Start trailhead, which was definitely a rough road, but not as terrible as I was expecting based on the other trip reports. Given, I was driving a truck, but there were Sedans parked in the parking lot, so it is doable in a regular car, you just have to take it slow.
I started this hike from the trail that starts from the trailhead left of the parking lot. The trail is split in two, but they both come together in about 1/2 mile, so it doesnt matter which one you take. About a mile from the parking lot is a sign indicating that you are on Ed's trail. The views and the wildflowers are incredible the whole way. As other trip reports mention, along the hike you'll walk through and arch and then get to a rock scramble. The trail continues around, showing off views of Hood, Adams, St, Helens, and in the distance, Rainier, and more wildflowers than you can imagine.
I reached the junction with Bluff Mountain and Silver Start trail and decided to go the 1/4 mile to Silver Star summit. From the Summit you have views of Vancouver and Portland and the Willamette Valley, as can see hikers coming in from Bluff Mountain Trail.
I took Silver Star trail back down, which is mostly a rocky old road bed. I took the Chinook Trail a little ways before heading back to the parking lot.
On the drive home, I tried taking L1100 instead of 4190. L1100 is currently used as a logging road, so is in much better condition than 4190 or 41. From the parking lot, take 4190 2.5 miles until it connects with L100, where you will turn left to get onto L1100. From there, drive 6.6 miles until you reach pavement, where you will turn right. From here drive 2.3 miles until you reach Sunset Falls Road. Turn Left on Sunset Falls Road, and then you will drive 2.0 miles and turn left once you have passed Moulton Falls County Park. This way still has you driving on 4109 for a little ways, but cuts out most of the bumpiness.
