We are going to head south along 101 in early April, and would like to find a relatively inexpensive dunking place. No mud, no massage, no overnight...just soak for awhile. Best thing I have found while Googling is in Arcata. Any comments, suggestions, reviews?

How far south on 101 are you going? There's Oasis in Occidental (way off 101). Central Coast has Avila (either Sycamore or Avila hot springs).

Only as far as Fairfield (which is not on 101, I know). We've been to Avila...Occidental doesn't show up in the cities index of my Rand-McNally atlas. Right now Vichy Springs in Ukiah looks good.

this may not be of much help but i know there's one in big sur...

Try yahoo maps. Occidental is west of Santa Rosa. I remember getting taken there for a Basque eating experience.

Osmosis is expensive and offers no hot springs. One "soaks" for about 15 minutes in an enzyme bath of cedar shavings. It is really relaxing, however.

Vichy Springs is a good pick. Another idea is Wilbur Hot Springs. You would turn of 101
on 20, head east to Wilbur. When you have finished your soak you would continue
down to Fairfied and 80 through the Napa Valley on 29. Another place is Harbin Hot Springs in Middletown.
Also, some locals in Calistoga offer
day use. You might try Indian Springs
(fabulous pool!)
