Hi Florian. Here's a Summit Post link.
http://www.summitpost.org/eureka-peak/560039I did the trail, which is, as you mentioned, rather nondescript. There was an interesting canyon off to the south that I went off trail to explore, and that was kinda nice. I saw the dirt road they mention in the write-up, but saw no traffic on a Saturday afternoon in prime season, so it's not a very busy location. Might be fun to bike it sometime via the road if it's not too sandy on my mountain bike, or even to drive up and let the sun set while just relaxing and reading or playing the guitar. I'd like to take in the views during and after sunset.
