What to Pack

Bring more water than anticipated, especially for natural hot springs without facilities, and consider electrolyte supplements for extended soaking sessions.

Etiquette Guidelines

Clothing-optional hot springs require heightened awareness of personal boundaries and respectful behavior. Always ask permission before joining occupied pools and maintain appropriate conversation topics honoring the peaceful atmosphere.
