I've removed the parenthetical remark, added a website, and changed the name to the full name on the website.

There are some strange things here that suggest some sort land dispute is going on.

1) The trails on OSM are more numerous that the map on the website and only bear a passing resemblance.

2) The parking area shown on the website is marked private on OSM.

3) Strava heatmap seems to roughly show activities on the trails mapped on the website, but doesn't show a clear point of entry.

User MartyMartPa did a lot of the editing on this park and I'll suggest he look at this note.
