In true Boxer spirit, as soon as Timber was off leash, she sprinted away, quickly losing me in her sight. As I yelled through the park "TIMBER" and hoped no one thought that there were falling trees, I finally saw her about 500 yards away sprinting back toward the road and parking lot. She clearly couldn't hear me. When she finally saw me running back down the hill, and she returned to me, she knew she was in trouble, and went straight back on her leash for the rest of the hike.
There is very little shade along the trails, so bring water for yourself and your dog. There was 1 water spout that I saw along the way on one of the trails, but you'd have to get to it first in order to get the water. So, just bring your own. There were some nice benches and places to sit along the way to enjoy the views.
We accumulated a couple miles of walking the trails, and then set out on the 2nd half of the adventure: Lunch and Wine! I wanted to check out a new restaurant, and it's now my favorite place in Napa for lunch. It's called Heritage Eats, and I can only describe it as a delicious salad/sandwich version of Chipotle. You pick your meat, your toppings, etc. They have some great flavor combinations like Jamaican Jerk, and Cowboy Steak. They also have a dog friendly patio for enjoying lunch together.
After lunch, we stopped by Goosecross Winery for a tasting. We are members here, so it's free tastings :) They also are dog friendly on their patio. So, after a nice hike, with a full belly from lunch, and few wine tastings, Timber and I had a wonderful adventure and called it a day.
