I live next door the Hole in the Rock and as a trail runner, I find myself running up it frequently. I want to clarify that I give this 5 stars as a family recreational site - not as a hiking or running trail.
This is a great .25 mile hike for a family. I started taking my kids there when they were 3 years old. My son is as clumsy as they come and even he can manage the trail. Most of the trail is stairs although there is some loose rock. Today, I watched a two year old climb the whole thing on her own.
The view is pretty amazing for such a short little trail. Sometimes in the morning I run up and down and I never actually stop to take a breath and look. But when I do, I always think to myself, 'Wow, I need to stop and taking a breath more often'.
