Explore San Sebastian’s highlights with a guided walking tour, visiting historic sites and enjoying an self-guided visit to the Aquarium for a complete day.
San Sebastian Aquarium Entry Ticket and City Walking Tour: A Deep Dive into the Basque Gem
If you’re heading to San Sebastian and want a taste of its history, architecture, and marine life, this combined tour offers a well-rounded experience. For just $51 per person, you’ll get a guided walk through the city’s most iconic areas, plus your own exploration of the San Sebastian Aquarium. With a solid 4.7-star rating based on three reviews, this tour promises an engaging blend of culture, history, and marine wonders.
What we really like about this experience is the chance to see both the historic heart of the city and the modern aquatic displays in one go. The guided walk is intimate, limited to small groups of eight, which means plenty of personal attention and chances to ask questions. However, the tour’s duration—about 2 to 3 hours—means you’ll need to pace yourself if you want to soak it all in. This experience suits travelers who enjoy a mix of sightseeing and self-paced exploration, especially if you’re curious about San Sebastian’s architecture and history but don’t want to spend all day on one activity.


Looking to discover more of San Sebastian? Consider these other city tour options
This tour offers a comprehensive glimpse of San Sebastian in a manageable timeframe. We love that it blends a guided walk through the most emblematic parts of the city with free time at the Aquarium, giving you both expert commentary and personal discovery space. The tour is designed for those who want a sense of the city’s charm while also enjoying the marvels of marine life.
Pricing at $51 per person is quite reasonable, considering it includes both a guided tour and entry to one of the city’s top attractions. Plus, the small group size—only up to 8 people—means you’ll likely get more interaction and tailored commentary than in larger tours.
Start at the Oficina de Turismo, right at Alameda del Blvd., where your guide will meet you and explain the plan for the day. From there, the tour unfolds in two main sections: the city walk and the Aquarium visit.
Guided Tour of San Sebastian (around 1 hour)
The walk begins at the border of Old and New Towns, an area steeped in history. You’ll walk through the winding streets of the Old Town, known locally as Parte Vieja, where narrow alleys hide pintxo bars and centuries-old churches. Here, your guide will highlight the city walls from the 19th century, illustrating how the city expanded and evolved.
The guide will point out landmarks like the Hotel de Londres and Maria Cristina, both built during the early 20th century and influenced by Queen Maria Cristina’s reign. Expect to learn about how these buildings reflect the city’s growth during that period. The Buen Pastor Cathedral is another highlight—an impressive neo-Gothic church that dominates the skyline and offers insight into San Sebastian’s religious and architectural history.
Old Town Exploration
Your guide will lead you through the serpentine streets, revealing hidden corners and sharing stories behind the architecture. The pintxo streets, famous for their vibrant food scene, will be discussed—not just for their culinary offerings but also for their historic significance as social hubs.
Expansion of the City in the 20th Century
Next, we move toward the newer parts of San Sebastian, where the city’s expansion during the early 1900s is visible in larger buildings and wider streets. This segment provides context for how the city adapted to modern tourism and urban development.
Self-guided exploration at the San Sebastian Aquarium (about 1 hour)
After the guided walk, you’ll have time to explore the Aquarium independently. The entrance is included in the tour price, and the experience is designed to be flexible. From the reviews, we know that visitors appreciated the chance to wander at their own pace, taking in marine exhibits and ancient skeletons of sea creatures.
The Aquarium is a key highlight—not just for families but for anyone interested in marine biology. Expect to see a variety of living sea creatures, perhaps shark tanks, and learn about marine ecosystems. And if history interests you, the skeletons and fossils reveal the ancient marine life that once thrived in this region.

If you enjoy exploring San Sebastian on foot, these walking tours might also suit your style
One reviewer noted, “The duration of the guided tours should comply with the specifications,” hinting that the actual walk might sometimes feel a tad brisk. Others appreciated the intimate nature of the tour, with one mentioning, “Limited to 8 participants, so it feels more personal.” These insights suggest that if you prefer a more relaxed pace or additional commentary, you might want to ask your guide for extra details.
If you’re a traveler craving a cultural and historical overview with a dash of marine exploration, this tour ticks those boxes. It’s also ideal if you prefer a small group setting and the flexibility of a self-guided Aquarium tour. It’s less suited for those wanting a longer, more exhaustive sightseeing experience, or those with mobility issues (though wheelchair accessibility is offered).

This San Sebastian tour offers a well-rounded introduction to one of Spain’s most beloved coastal cities. You get to walk through historic neighborhoods, admire iconic buildings influenced by Queen Maria Cristina, and enjoy the lively pintxo streets—all with a knowledgeable guide leading the way. The bonus of self-guided access to the Aquarium adds an engaging dimension, especially for marine life enthusiasts or families.
The price point reflects good value, considering the combination of guided sightseeing and the Aquarium visit. Small group sizes enhance the experience, making it more interactive and personable. The tour strikes a balance between structured guided exploration and personal discovery time, which many travelers find ideal.
This experience is perfect for first-timers who want to hit the highlights without feeling rushed, or for those curious about San Sebastian’s architecture and marine world. It’s best suited for travelers who appreciate a balanced pace, authentic insights, and a mix of guided and independent exploration.
