No special access issues
The road is in some kind of a way a private road so you can park to the left a few meters ahead at the beginning of the road, the gate never closes. It is possible to park further ahead, there are perfect car spots for every boulder and it is not that big of a deal.
If you don´t want to park on this road at all there is a spot for two cars next to this one (see map).
If you use Google maps it will tell you to drive around everything and arriving on an end road so use Apple Maps instead.
