Hunter Spring

Description:
You will see the mailbox above. There is a pipe running from the right side of road. The water source for St. Helena is slightly closer than Rattlesnake Spring. There are also less people waiting as it does not receive as much traffic. The water is very clean, and it tastes great. Rattlesnake spring is not something I've been to, but someone I spoke to who had said they were similar. I haven’t tested the water, but I would like to in the future.

If you are coming in from 29/Sonoma Calistoga, you will want to pass downtown Angwin. Go a few more miles and then turn right to locate the pipe with a plank of wood on the ground at the end of the road. It's obvious that you've passed it when you see the mailboxes at your left beginning with the number 1435. Google streetview will show you the pipes and wood plank.

Rattlesnake Spring can be found in California (county Napa), at latitude - longitude coordinates N 38.67213/W -122.58971. It is located at the highest point of Lake County Highway 29 (just south of Middletown). It is at the NW corner in Napa County. From there, one can drive north into Lake County. Hiking west into Sonoma County's Robert Louis Stevenson St. Park brings you right into Sonoma. It's on the other side of the road. It may have a few cars lined up to fill it when it's flowing. According to my knowledge, it will flow throughout the year. However, it may be plugged by the county from time to time. It is much preferred over Harbin by many Lake County residents. Although I haven't tried it yet, I am keen to ensure it is high quality.
