In the peaceful country, you will see a beautiful beach, Avila Beach.

It is just three minutes’ drive from the great beach to the hot springs hotel.

Take extra care

Sycamore Mineral Springs is a hotel in the sophisticated air, where provides hot springs water as by-product of oil drilling.

From my point of view, it looks nonsense if you find the rate for lodging expensive and try the walk-in soak.

The Hillside Hot Tub

Water in tubs for walk-in guests is badly chlorinated and you cannot feel the nature at all.

Overnight guests can enjoy the real water at each room, but take extra care when reserving the rooms.

Usually affluent people in the United States do not like the kind of sulfur smell, so that the more luxury rooms provide worse quality of hot springs water, being artificially processed.

Spa Suite-Queen "mythical"

In conclusion, only the three buildings named Adventure, Harmony, and Mythical have the real water directly piped from the source of the springs.

As for Mythical, the hot tub is located in the balcony next to the bedroom.


The plastic tub does not look nice, but the water is awesome.

In addition to the strong smell of hydrogen sulfide, you will notice the characteristic smell of oil, which conjures up image of typical hot springs in Japan.

Mineral Tub

The temperature is around 111 degrees F at the water outlet, and it looks yellowish at first.

However, the color changes to beautiful milky-white if you leave it for a night, due to oxidation.

The water in the morning becomes cold, but you can add fresh hot water for comfortable soaking.


The ageless song in the 1960, California Dreamin’ of Mamas & The Papas dreams of warm and shinning California from cold and gloomy New York.

Sycamore Mineral Springs is one of the best places in such California for dreaming of Japanese hot springs.
