Warm water, honest rules.

Thermal pools, hammams, hot springs and the sea: what to wear, what it costs and who may enter, quoted from the venues’ own rules and dated. Mostly in the sun, with a few cold-weather soaks for winter.

The rulebooks

Read the house rules before you pack

Built from what the venues publish, not from one visit. Every chapter separates what a bath requires from what people merely tend to do.

All rulebooks
Book ahead

Tickets worth booking before you go

The popular baths sell timed entry and fill up in peak periods. Each card links to the exact listing our rulebook covers; read the rules first, then check the date you want.

These are affiliate links: if you book through one we may earn a commission, at no extra cost to you. Booking direct with the venue is equally fine. Disclosure

Destinations

Trips built around warm water

Hammams, thermal pools and hot springs, mostly where the sun shines, with a few winter soaks for when it does not.

How a page gets made

We read the rules so you don’t arrive guessing

No page claims a visit that did not happen. When something is our opinion, it says so.

  1. Find the source

    The venue’s house rules, the park authority, or a public-health body. Not other blogs.

  2. Quote and date it

    The exact wording, a link, and the date we read it. Rules and prices change.

  3. Rule or custom

    What gets you asked to leave is kept apart from what people simply tend to do.

  4. Link only what fits

    A booking or product link appears only where it matches the page exactly.
