The very popular, very busy Rattlesnake Ridge. Popular for it's proximity to Seattle, moderate incline and great views. We had just bought our new hiking boot, Obos, and were ready to put them to the test with the pup in hand. The incline was challenging, but doable. We learned a lesson with hiking with Cooper though, it's really hard. He is still a puppy and pulls so hard on the leash making it not enjoyable for all. The top was beautiful though and worth the trek. We wanted to get this one done for the season before it gets crazy busy there in the summer. I also found out my hiking boots were a size too small, learned that the hard way on the way down the hike. Good thing REI has an excellent return policy.
