This trail is only available by guides at Holden Arboretum on certain dates. I didnt go to stebbin gulch hike. However, Holden arboretum charges $10 to go on their trails which are mostly graveled. Very easy walking. There is a canopy trail but you pay $14 instead of $10 if you want that. Overall, it wasnt worth the money to me. Ill give it a 3 star because it has potential and i didn't get to do stebbins gulch. I was told that the hike is difficult and dangerous and thats why a guide is necessary.
