Open Question: Redwood forest trek question?

Me and a group of 10 friends (all around 16) and three dads are looking to do a redwoods trek, probably about 50 to 70 miles over a week or so. We haven't found any options for back country trails. Has anyone done this, any recommendations, where should we start? We hope to do this in June at some point.

Thanks
