We understand if you want to visit the popular Szechenyi Baths and Pool off peak hours, or when tourists are less frequent in the baths.
Obviously, early morning hours are less crowded, the pools are almost exclusively used by local regulars who wish to do their swimming laps in the outdoor sports pool between 6am and 8am, or who wish to use the spa facilities when they are not packed. Later on the day, especially mid and late afternoon, the baths and pools fill up with locals and tourists – especially in the summer months (from June to September).
So, if you want to pick the best time of the day, we recommend visiting the baths earlier in the day, either in the morning around 10am, or around noon, e.g. 1 pm. As one of the tourists wrote in their Szechenyi Baths review on a travel forum “We were there today, arrived at 1.30pm, and by 3.30pm it was chock-full of tourists. Earlier it was quiet and only older locals were bathing.”
Weekends are, similarly to peak hours, more popular, so to have some more personal space in the thermal spa baths, you may wish to schedule your bath visit for a weekday (any week day open, Monday, Tuesday, Wednesday, Thursday, Friday). All days are mixed, so you don’t need to plan ahead for coed visits.
