Started at the visitor center, followed the vineyard trail and then went up the Crescenta View trial towards Mt. Lukens. It was a very enjoyable hike in the cool mountain air. A good workout but not as rigorous as climbing say Mt Baldy or Mt. Wilson, the switchbacks are very plentiful and they keep the ascent constant but not that steep. The views are stunning and the Manzanita, sage and Ceanothus are looking very vibrant and healthy and I can't wait for the spring wildflowers. I would not recommend this trail for mountain bikes as it is very rocky once you begin making your way up and it is also very narrow in spots and tough to pass with hikers. I would also recommend hiking shoes and/or hiking poles for a less treacherous experience.
