Bilbao / The verdict
Is a San Juan de Gaztelugatxe day trip from Bilbao worth it?
Yes for travelers who can manage a steep one-kilometer path and 241 unshaded steps, and who can plan around it: the islet, the staircase and the hermitage draw near-universal praise. The free timed ticket, hourly buses and long approach decide who should go.

The Bilbao story
Bilbao is the comeback story that actually worked: an industrial port that bet on architecture and food and won. The Guggenheim is the headline, Gehry's titanium curves wrapping a cathedral-like atrium, but the real pleasure is the package: a handsome, walkable city where the pintxos bar is a way of life and even the 1909 warehouse the Azkuna Zentroa occupies got Starcked into 43 different columns. Ride the Artxanda funicular at dusk for the whole bowl of the city, the river curve and the museum in one frame.
The verdict in 30 seconds
It depends
Yes for travelers who can manage a steep one-kilometer path and 241 unshaded steps, and who can plan around it: the islet, the staircase and the hermitage draw near-universal praise. The free timed ticket, hourly buses and long approach decide who should go.
Go if
- You can handle a steep kilometer-long approach plus 241 stone steps, and want the most dramatic sight on the Basque coast
- You are a Game of Thrones fan, since this is the real staircase used as Dragonstone
- You can reserve the free timed ticket ahead and give the better part of a day to the trip
Skip if
- Stairs or steep grades are a problem: there is no step-free route to the hermitage and reports describe travelers turning back
- You want a quick half day: the Bilbao to Bakio bus alone takes about 74 minutes and off-season connections to the site run weekdays only
- You will be in town on a controlled-access day with no reservation, when entry is impossible and tickets can sell out
What it costs
- Timed entry ticket (controlled-access days): €0 (Free but required on controlled days such as summer, weekends and holidays; outside the calendar the site is walk-in). Official source, checked Oct 2026.
- Bizkaibus single Bilbao to Bakio: €3.40 (Zone 1 to zone 4 fare on line A3518; cheaper with a Barik card). Official source, checked Oct 2026.
What travelers report
Based on 14 traveler reports (Mar 2025 to Aug 2026) and the official sources linked on this page. 0 were negative.
What people like
- The islet, the zigzag staircase and the hermitage draw near-universal awe and are repeatedly called the standout sight of the Basque coast.
- 3 of the logged reports describe the climb as hard but worth it, arriving back in Bilbao exhausted and educated.
- 2 of the logged reports describe a smooth entry with the free timed ticket when they planned around it.
- 2 of the logged reports recommend pairing the climb with Bermeo, Mundaka or Gernika to justify the journey.
What people complain about
- 4 of the logged reports stress the climb as the filter: 241 exposed steps plus the steep approach turn back a share of visitors, and one post estimates half never attempt it.
- 3 of the logged reports flag the logistics: the Bilbao bus only reaches Bakio, the onward leg is thin off-season and one itinerary calls the coastal hops nearly impossible without a car.
- 2 of the logged reports describe the crowds: peak days have run to 2,400 visitors and campervan parking is a nightmare.
- 1 logged report arrived on a holiday without a booking and could not hike at all.
How to do it right
- Reserve a free timed ticket on the official Tiketa booking page as early as possible; on controlled-access days such as summer, weekends and holidays there is no entry without one.
- Take Bizkaibus A3518 from central Bilbao to Bakio (about 74 minutes, roughly hourly), then walk 35 to 45 minutes to the trailhead or connect to the weekday A3524 minibus.
- Choose the gentler Ermu path that reaches the steps directly, or the steep Urizarreta descent past the Eneperi viewpoint if you want the classic photo angle first.
- Add Bermeo to the day: the Gaztelugatxe visitor center there handles same-day entries and runs a local bus and guide service, and Bermeo itself is worth an hour.
- If you would rather not manage buses and permits, book a guided day tour that bundles transport, the access permit and towns like Gernika and Mundaka.
The trap to avoid
Showing up on a controlled day without a reservation. The free ticket is capped at 1,462 entries a day, each booking cancels one hour after its slot, and reports describe travelers being turned back at the trailhead.
Why this verdict
The reports do not argue about whether the place is worth seeing: the islet, the zigzag staircase and the hermitage above the sea draw near-universal awe, and travelers who took a timed ticket describe a smooth system with almost no waiting. The verdict splits on who can enjoy it. The climb down and back up in the open air, plus 241 steps, turns back a share of visitors, and there is no step-free alternative. On peak days crowds have run toward 2,400 visitors a day, which is exactly why the reservation cap exists.
The second filter is logistics. Entry is free, but on controlled days (roughly summer, weekends and holidays on the official calendar) a timed ticket is mandatory and capacity is capped at 1,462 a day. Reports describe travelers arriving on a holiday without a booking and being turned back. Public transport adds friction: the Bilbao bus only reaches Bakio, about a 74-minute ride, and the onward connection to the site runs weekdays only outside summer, which is why one guide calls the do-it-yourself trip painful and why day tours that include transport and the permit make sense for many visitors.
Timing and tickets
Book the free timed ticket on the official page as soon as the calendar opens, and arrive inside your slot, since unused reservations cancel after one hour. The A3518 bus from Moyua to Bakio runs about hourly; from Bakio, walkers use the coastal path while the weekday A3524 and the summer A3517 loop reach the site. The gentler Ermu path is the route reports recommend for the climb. Pair the day with Bermeo, where the visitor center opened in June 2026 handles same-day entries and runs a local bus and guide service.

Questions
Do you need a ticket for San Juan de Gaztelugatxe?
Only on controlled-access days, which cover roughly June through September plus weekends and holidays on the official calendar. The timed ticket is free through the official booking page, daily capacity is capped at 1,462, and an unused reservation cancels one hour after its slot. On open days you can simply walk in.
How do you get to Gaztelugatxe from Bilbao?
Take Bizkaibus A3518 from Moyua in central Bilbao to Bakio (about 74 minutes, roughly hourly), then either walk 35 to 45 minutes to the trailhead or use the A3524 connector, which on off-season dates runs weekdays only. In summer the A3517 loop links Bakio, Gaztelugatxe and Bermeo. The alternative is a guided day tour with transport included.
How hard is the walk to Gaztelugatxe?
Reports describe two approaches of about one kilometer: the steep Urizarreta descent from Eneperi and the gentler Ermu path that reaches the steps more gradually. From the sea bridge, 241 steps climb to the hermitage, and there is no step-free route anywhere on the site. Most reasonably fit visitors manage it slowly; it is the exertion, not the distance, that filters people out.
Can you visit Gaztelugatxe without a tour?
Yes, and it is cheap: entry is free and the bus fare from Bilbao is 3.40 EUR each way. The catch is logistics rather than cost, since the onward connection to the site is limited outside summer and weekends. Travelers who do not want to manage that trade a small cost for a guided tour's included transport and guaranteed permit.
Is Gaztelugatxe open all year?
The site is open year-round and is free, but the timed-ticket system only operates on the controlled days listed in the official calendar. Bad weather can close the paths, and strong wind is common on the exposed coast, so check the official page on the day you go.
