About Diamond Mountain Casino
Diamond Mountain Casino and Hotel operates at 900 Skyline Road in Susanville, California, owned and operated by the Susanville Indian Rancheria. The property sits in Lassen County in the northeastern California interior, an area where gaming options are extremely limited. The casino offers a slot floor, table games including 3 Card Poker, Baccarat, Blackjack, Electronic Roulette, and Roulette, alongside an on-site hotel, spa, and pool.
Baccarat is one of the most-played table game formats at Diamond Mountain.
Standard Blackjack anchors the blackjack-family side of the pit.
The 1928 year-opened entry likely refers to the Susanville Indian Rancheria’s establishment date rather than the casino, which as a gaming venue would have opened under IGRA post-1988. Susanville is the Lassen County seat at roughly 4,200 feet elevation.

The roulette listing is notable: California tribal casinos typically use card-based roulette variants rather than the standard wheel format, and guests should confirm the specific format in use.
