Arastradero Preserve
I got some fresh air.
I thought it was a decent place to unwind and get some fresh air and not otherwise be cooped-up in a Silicon Valley business hotel with not much to do. I'll say that there are certainly advantages to living in Silicon Valley, but I wouldn't call it a vacation destination. But I think there are a decent number of parks with nice walking trails. This is one of them. If you got a small kid who can walk but with a limited range (under 3), and you want the kid to get introduced to the outdoors, this is a good trail.
The Redtail Loop was pretty short. I must have been thinking of a different one when I thought it was 3 or 4 miles. It was probably for the better I only walked 1.4 miles though. It started raining by the time I left.
