Researched guide — we have not visited Therme Erding ourselves. Built from Therme Erding’s own price page, FAQ and house rules (Haus- und Badeordnung, in force since 23 February 2026). Part of our rulebooks.
Therme Erding, just outside Munich, calls itself the largest thermal bath in the world. Its ticket page shows two base prices for the same day and two surcharges that never appear at the till, because they are booked onto the chip in your locker key when you pass a turnstile. Add a textile-free sauna world that first-timers hear about only after they arrive, and it is easy to pay for the wrong ticket or walk into the wrong zone. This page explains how the three zones, the tickets and the rules fit together, quoting the venue’s own pages.

Do you have to be naked at Therme Erding?
Only in one of the three zones. The pools and slides (the Therme) and the quieter VitalOase are swimsuit areas. The big sauna world, the VitalTherme & Saunen, is 16+ and, in the FAQ’s words, to be used “exclusively textile-free” (Therme Erding FAQ). If that is a deal-breaker, the FAQ points you to the textile saunas and steam rooms of the VitalOase, where you keep your swimwear on.
Textile-free does not mean naturist. The house rules say the sauna world “is not a naturist facility” and that once you finish bathing or cooling down you put on a bathrobe or towel, including in the restaurants (Haus- und Badeordnung, section 4). In the cabins you sit or lie on a towel large enough for your whole body, feet included. That is the same pattern we found across other German venues in our German sauna rules guide.
One entrance, three zones
| Zone | What it is | Age | Swimwear |
|---|---|---|---|
| Therme (with wave pool and Galaxy slides) | Thermal pools at 34°C, wave pool, slide world | All ages; under 12 only with an accompanying person aged at least 16 | On |
| VitalOase | Quieter mineral pools, rest areas, textile saunas and steam rooms | 16+ | On |
| VitalTherme & Saunen | More than 20 saunas from 38°C to 90°C, pools at 34°C, the Polaris cold pool at 14–18°C | 16+ | Off (textile-free) |
You move through them in that order. Therme guests reach the VitalOase through turnstiles next to the info point, and the sauna world is reached after a short walk through the VitalOase (FAQ). The venue describes Polaris as the largest cold-water pool in the world; we repeat that as its own claim.
Which ticket do you need?
Pick by the zone you want to end up in. Pools and slides only: the Therme ticket. Anything with the textile-free saunas: plan on about €70 for a weekday full day, €77 at weekends, whichever way you get there. The two base tickets, as published on the price page:
| Ticket | Weekday | Weekend, holidays, school holidays |
|---|---|---|
| Therme, 1 day (pools, wave pool, Galaxy) | €52 | €59 |
| Therme, 6 / 4 / 2 hours | €49 / €37 / €25 | €56 / €44 / €32 |
| VitalTherme & Saunen, 1 day (16+, all areas) | €62 | €69 |
| VitalTherme & Saunen, 6 / 4 / 2 hours | €59 / €47 / €35 | €66 / €54 / €42 |
| VitalOase add-on on a Therme ticket | +€10 per stay | |
| Textile-free sauna use | +€8 per stay | |
| Extra time | +€3 per started 30 minutes | |
The surcharges are where people get confused. The price page lists textile-free sauna use as +€8 on the VitalTherme & Saunen ticket, so €62 + €8 = €70. The FAQ describes the route from a Therme ticket instead: €10 is booked onto your chip once when you enter the VitalOase, and another €8 once when you cross into the sauna world, after which you can switch back and forth as often as you like. €52 + €10 + €8 is also €70. Either way, the full day with saunas lands at about the same price; check the total on your chip at the exit.
Two cheaper options exist. The early-swimmer rate, Monday to Friday with entry before 12:00, gives two hours for €22 on the Therme ticket or €32 (plus €8 for the saunas) on the VitalTherme & Saunen ticket. And the house rules say you cannot interrupt a stay on the same ticket, so do not plan to pop out for lunch.
Opening hours and whether to book
Standard hours for all three zones: Monday to Friday 10:00–23:00, Saturday 09:00–24:00, Sundays and Bavarian holidays 09:00–23:00. Bathing and sauna end 20 minutes before closing. The Galaxy slide world keeps shorter hours: Monday to Thursday 13:00–21:00, Friday 13:00–23:00, Saturday 09:00–23:00, Sunday 09:00–21:00, earlier on days without school in Bavaria (price page).
Booking is optional. The venue says an online reservation gives you guaranteed entry if there is an entry stop on your day, which it links to weekends, public holidays and school holidays. On a quiet weekday it matters less. Christmas and New Year have special hours (24 December 09:00–14:00, 31 December 09:00–17:00), so check those dates on the venue’s calendar.
What is closed right now
The price page lists current maintenance closures. In October 2026: the Finnenstube sauna in the sauna world and the High Fly slide are temporarily closed, and the Sole-Grotte and Vital-Grotte in the Therme are closed from 20 to 29 October 2026. These change, so look at the “Revisionen” tab the week you go.
Getting there from Munich
Take the S2 to Altenerding. From Monday to Friday, city buses 550, 560 and 580 stop at the door; on Saturdays, Sundays and holidays it is line 570. The FAQ also mentions a signposted 800-metre footpath. Driving is easy: 600 open-air spaces and 1,050 in the multi-storey car park, all free (FAQ).
Staying the night in Erding
The sauna world stays open until 23:00 on weekdays and midnight on Saturdays, and the house rules do not let you interrupt a stay on the same ticket. If you want a full day with an evening session, a room in Erding itself means no late S-Bahn back to Munich. We have not stayed at any hotel there and do not recommend a specific one; compare what is available for your dates: hotels in Erding on Booking.com (affiliate link).
The key on your wrist is your wallet
You do not need cash inside. Food, drinks, massages and zone surcharges are booked onto the round chip of your locker key, and you pay at the exit in cash or by EC card. The house rules require you to wear the key on your body the whole time. Losing it costs a flat €45 plus whatever was booked on it, so keep your entry receipt and remember your locker number. Valuables lockers in the entrance and in the sauna world take a €2 coin as deposit.
What to bring (and what to leave at home)
- Large towels. The FAQ says “big enough” for sauna use; the sauna rule is a towel under your whole body. Two is sensible. Forgot? A towel rents for €5 plus €15 deposit, a bathrobe for €7 plus €30, while stock lasts.
- A bathrobe if you plan to sit in the sauna-world restaurants, where you must be covered. A thin waffle robe dries faster and packs flatter than thick towelling; our Amazon Essentials waffle robe review covers one option, including the runs-large sizing complaint. Renting one on the day works just as well.
- Bath shoes. Allowed, and the house rules recommend non-slip ones outside the pools. Mark them; everyone’s look alike.
- Toiletries: shower gel, shampoo, deodorant. You must shower before entering, and soap is not allowed outside the showers.
- A €2 coin for a valuables locker.
- Old swimwear and no good jewellery. The house rules warn that the sulphur in the water can discolour or bleach swimwear, jewellery and watches, and the venue accepts no liability for it.
Leave at home: a picnic. One drink and a small snack, such as a piece of fruit, per person is tolerated; glass may be taken off you and cool bags must stay closed. Alcohol from outside is not allowed, and the bars serve at most four alcoholic drinks, or five on a full-day stay. Swimming goggles are banned in the textile-free pools. Our what to bring to a German sauna checklist covers the rest.
Rules that surprise first-timers
- No phones in the sauna world. The house rules forbid using smartphones, tablets or any recording device in the textile-free area, and the FAQ says the point is your privacy. Leave it in the locker.
- No reserving loungers with towels or bags; staff may clear them.
- Quiet in saunas and steam rooms. Aufguss infusions are done only by staff, and you may not bring your own scents. See our Aufguss etiquette guide for what to do when the sauna master arrives.
- No sauna after drinking. The house rules ban sauna use under the influence of alcohol and say only healthy people should use the saunas; if in doubt, ask your doctor first.
- Children and the mineral pools. Under-16s cannot enter the VitalOase or the sauna world. The FAQ advises against taking children into the mineral pools, such as the sulphur pool, because the mineral concentration is too high for them, and asks for swim nappies for babies.
