Start our Regensburg adventure from the heart of the city - the Old Town, which is a true open-air museum. Wandering through the narrow, cobblestone streets, you will feel like you are traveling back in time. The first point on our tour is the Stone Bridge (Steinerne Brücke), a medieval engineering marvel dating back to the 12th century, which still impresses today with its monumentality. It is an ideal vantage point for viewing the city skyline and the Danube River.

Not far from the bridge is one of Regensburg's greatest attractions - St. Peter's Cathedral. This Gothic temple with its distinctive towers dominates the city and is an absolute must-see on any visit. Admission to the cathedral is free, which fits perfectly into our budget tour.

After visiting the cathedral, it's a good idea to head towards the Old City Hall (Altes Rathaus). This complex of buildings dating back to the 14th and 15th centuries is not only a beautiful example of Gothic architecture, but is also home to a fascinating historical museum. Although there is a fee to enter the museum, just admiring the building from the outside and strolling around the surrounding square costs nothing, and provides a lot of excitement.

For those who want to feel the true spirit of medieval Regensburg, we recommend a visit to the Stadtamhof district. This is a charming enclave on the other side of the Danube, connected to the Old Town by the Stone Bridge. Narrow streets, colorful townhouses and picturesque backstreets create a unique atmosphere, ideal for leisurely strolls and discovering the city's hidden treasures.

At the end of this part of the tour, visit Haidplatz - one of the most beautiful squares in the city. Surrounded by historic townhouses, it is the perfect place to sit in one of the many cafes and watch the bustling city. It's also a great starting point for further sightseeing, as there are many interesting sights and attractions nearby.

After a busy tour of the historic center, it's time to take a breather and relax by the Danube River. Regensburg offers many opportunities for relaxation in a natural setting without straining our budget.

One of the most beautiful places to relax is Donau Park, a vast green area located on the banks of the Danube. This park is a true oasis of tranquility in the heart of the city, ideal for both families with children and those looking for a moment of relaxation. Donau Park offers expansive lawns perfect for a picnic, walking and biking paths and playgrounds for the little ones. It's a great place to spend an afternoon enjoying the fresh air and beautiful views of the river. The park is open all year round and, most importantly, admission is completely free.

For those who prefer a more active vacation, we recommend a walk or bike ride along the Donaupromenade. This picturesque promenade stretching along the southern bank of the Danube is not only a great place to relax, but also an excellent vantage point for viewing the Old Town. The Donaupromenade connects to other paths, providing endless opportunities for walking and biking. Along the promenade, you will find numerous benches and resting places where you can enjoy the panorama of the city and the traffic on the river. What's more, there are restaurants in several places along the boardwalk where you can rest and eat, although for the thrifty, we recommend taking your own provisions and having a picnic by the water.

Another attraction worth considering is the Max Schulze Steig, a scenic hiking path that offers beautiful views of the Danube River and the surrounding hills. This route, though challenging in places, rewards you with magnificent panoramas and proximity to nature. It is worth remembering that the path can be slippery after rain, so use caution. Max Schulze Steig is ideal for lovers of active recreation and beautiful landscapes.

It is worth noting that all of these places - Donau Park, Donaupromenade and Max Schulze Steig - are available free of charge, which fits perfectly with the concept of budget sightseeing. They offer not only the opportunity for relaxation and recreation, but also a chance to admire Regensburg from a different perspective, away from the touristy hustle and bustle of the Old Town. These are ideal places to relax, recharge your batteries and immerse yourself in nature for a while, without leaving the city limits.

To conclude our budget tour of Regensburg, we would like to present some lesser-known, but equally fascinating places that will allow you to experience the city from a different perspective.

Let's start with a visit to the Stadtamhof district, which, although located just across the Stone Bridge, is often overlooked by tourists. This charming enclave offers the quiet atmosphere of a small town with narrow streets and colorful townhouses. Small local stores and cafes are worth a look here, where you can get a real feel for Bavarian life. A stroll through Stadtamhof is a great opportunity to take souvenir photos and discover less touristy corners of the city.

Another interesting site is the Dokumentationszentrum Reichsparteitagsgelände - a documentation center for the NSDAP party convention grounds. While it may seem like an unusual attraction, the site offers a fascinating insight into 20th century German history. The exhibition presents the history of Nazism and its impact on Regensburg in an educational and thought-provoking way. There is a fee to enter the center, but ticket prices are affordable and the educational value is great.

For nature lovers and quiet walks, we recommend a visit to Herzogspark. This small but charming botanical park offers beautiful gardens, small ponds and peaceful alleys. It's the perfect place to relax after a busy day of sightseeing. Admission to the park is free, making it an excellent option for frugal travelers.

Finally, it's worth mentioning the interesting 'Regensburg for free' (Regensburg kostenlos) initiative, which offers free guided tours of the city. These tours take place regularly and are led by volunteers passionate about the city's history. It's a great opportunity to get to know Regensburg through the eyes of local residents and learn many interesting facts that you won't find in guidebooks.

All in all, Regensburg is a city that offers countless opportunities to explore and discover, regardless of your budget. From the majestic sights of the Old Town, to the relaxing parks along the Danube, to the hidden gems in lesser-known neighborhoods, there is something for everyone. Remember that many activities, such as walking around the city, admiring the architecture or relaxing in the parks, are completely free. The key to a successful budget trip to Regensburg is good planning, taking advantage of free attractions and being open to new experiences. We wish you a fascinating journey through time and space in this remarkable Bavarian city!
