Frequently Asked Questions

Get answers to the most common questions travelers ask before visiting.

Across the booking platforms we compare, sightseeing tours dominate the options, with most also offered as boat cruises or helicopter tours. About 75% include a guide, and roughly a quarter offer helicopter access for a different vantage point. Group tours are more common than private options, though both formats are available. Tours typically run 1.5 to 5 hours, so you can choose between a quick scenic pass or a deeper exploration depending on your schedule.

Among the 8 tours we compare across booking platforms, prices range widely: most fall between $35 and $105, with a median around $55. You'll find options at both ends of the spectrum, from budget-friendly sightseeing cruises to premium helicopter tours that push toward $200. All of the options we compare offer free cancellation, so you can book with confidence and adjust if plans change.

Most tours bundle a guide into the experience, and many add audio commentary or headsets for richer storytelling. The boat-based options, which make up the majority of tours we compare, naturally include the cruise itself. Some packages fold taxes into the quoted price, while others add them at checkout, so check the fine print. About 90% of reviews are positive, with visitors frequently praising how much they learn and how well-organized the tours feel.

Most tours (75%) operate by boat, giving you a water-based approach to the castle and surrounding islands. The remaining quarter offer helicopter tours, which provide aerial views and a completely different experience. Boat tours suit travellers of all fitness levels and budgets, while helicopter options appeal to those seeking a premium, bird's-eye perspective. Both formats let you see the castle's riverside setting and architectural detail from unique angles.

Only a small number of the options we compare are flagged as likely to sell out, so most tours have reasonable availability. That said, booking ahead is worth doing if you're visiting during peak season (summer months) or have a specific date in mind. All options offer instant confirmation for most bookings, so you can secure your spot immediately and avoid last-minute disappointment.
