Budapest isn’t just beautiful—it’s built on a network of natural hot springs that have been used for healing and relaxation for centuries. Whether you’re in the mood for ornate architecture, rooftop views, or a deep soak in steaming mineral water, the city’s thermal baths are a must during your visit.

Here’s a guide to the best thermal baths in Budapest, what to bring, and insider tips to make the most of your spa day.

The Best Thermal Baths in Budapest

Gellért Thermal Bath

Walking into Gellért feels like walking into a museum. It is easily the most beautiful bath in Budapest, and definitely the most beautiful spa I’ve ever visited. With its colorful mosaics, stained glass, and Art Nouveau architecture, it looks more like a museum than a spa. It’s easy to lose your way inside the maze of hallways and pools, but every turn reveals something stunning. If you’re looking for elegance and relaxation, this is the one.

Vibe: Romantic, peaceful, elegant
Tip: Allow extra time just to wander and take in the beauty—seriously, it’s that pretty.

Széchenyi Thermal Bath

One of the most iconic spots in the city, Széchenyi is the largest and most popular thermal bath in Budapest. Located in City Park, this massive neo-Baroque complex has 15 indoor pools and 3 outdoor ones, surrounded by steam, grand architecture, and the occasional game of chess in the water. It’s touristy but worth it, especially in colder months when the contrast of hot water and chilly air is just magical.

Vibe: Lively, grand, social
Tip: Bring your camera, especially for those steamy outdoor pool shots.

Rudas Baths

Dating back to the 16th century, Rudas is one of the most atmospheric baths in Budapest. The central dome, octagonal pool, and Ottoman architecture give it an almost mystical feel. It’s also one of the only baths open late on weekends, and the rooftop hot tub offers sweeping views of the Danube and city skyline.

Vibe: Traditional, moody, ideal for sunset or night visits
Tip: Check the schedule—Rudas still has gender-specific bathing days and hours, especially in the historic Turkish section.

Lukács Baths

Less touristy and more popular with locals, Lukács offers a quieter, more laid-back experience. It’s also known for its wellness services, salt rooms, and healing water fountains where people line up with jugs to drink the spring water.

Vibe: Local, practical, low-key
Tip: Great for those looking to escape the crowds without missing out on the full spa experience.

What to Bring to the Thermal Baths in Budapest

Many of the essentials are available for rent or purchase on site, but prices can be steep and lines long. Here’s what to pack:

• Flip-Flops: These are mandatory in most baths, and buying them on site can cost around $10 or more. Definitely bring your own.
• Towel: Rental towels are thin and overpriced. A quick-dry travel towel is ideal.
• Swimsuit: Required at all co-ed baths. Bring one that’s comfortable for lounging and swimming.
• Hair Products: Thermal water can leave hair dry or brittle. Pack your own shampoo, conditioner, and brush.
• Lotion or Body Oil: After soaking, your skin might feel dry. Rehydrate with a good moisturizer.
• Water Bottle: You’ll be sweating in the saunas and soaking for hours—stay hydrated.

Best Time to Visit Thermal Baths in Budapest

Go early. The baths fill up fast, especially Széchenyi and Gellért. Arriving when they open gives you a peaceful atmosphere, cleaner facilities, and better photo opportunities.

Check the calendar. Especially important for Rudas, which has single-gender days or hours in some areas. Don’t get caught off guard if you’re traveling with someone of a different gender or hoping to experience all parts of the spa.
