How to Get to Gaztelugatxe From Bilbao
Tour, bus, car or taxi — the four ways to reach San Juan de Gaztelugatxe from Bilbao compared on cost, time and hassle, including the free reservation you still need.
San Juan de Gaztelugatxe sits 35 km east of Bilbao, roughly 45 minutes away by road. That single figure makes the trip sound trivial, and it is why so many visitors arrive at the problem late: the drive is short, but there is no year-round direct bus, the free car park fills before mid-morning in season, and none of the four options removes the timed entry reservation unless you have booked a tour that includes it.

Read the third row before the first. Entry to Gaztelugatxe is free, but on busy dates the Bizkaia provincial council issues free timed tickets through its own portal and there is a daily cap — compulsory daily through summer, at weekends from late March into October, and over Easter, Christmas and Spanish public holidays. Three of the four options above leave that entirely with you, and in July and August the slots are typically gone two to three weeks out.
By car: fastest, and the option with the most that can go wrong
Take the BI-631 towards the airport, continue past Mungia on the BI-2101 to Bakio, and follow signs from there. About 45 minutes from central Bilbao in normal traffic.
The main car park by the road is free; the Eneperi restaurant car park costs about €3 and is better placed for the descent. Both fill during high season, and there is nowhere convincing to overflow into — the approach road is narrow and the shoulder is not parking. In July and August, arriving after about 10:00 without a plan is how people end up driving back to Bakio.
You will still need your own reservation, and you should have it before you set off. A car makes the whole coast reachable in a day, which is its real advantage: Bakio’s beach, Bermeo’s harbour, Mundaka, Gernika and the Urdaibai reserve are all within half an hour of each other.
By bus: cheapest, and only workable on a weekday
There is no direct Bizkaibus service between Bilbao and Gaztelugatxe for most of the year. The route is:
- A3518 from Plaza Moyua in Bilbao to Bakio — about 40 minutes, roughly hourly.
- Then either the A3524 Bakio–Gaztelugatxe–Bermeo connection, which runs weekdays only, every two hours from early morning to early evening, as an eight-seat taxi-bus that takes cash; or a walk of 5 to 6 km uphill, around an hour and a half.
- A direct summer line, the A3517, appears in the high season.
At weekends outside summer the connection does not run at all, which is what turns a €3 fare into a three-hour walk. Bizkaibus timetables change seasonally, so confirm before you travel. Our Bilbao to Gaztelugatxe by bus guide works through the timings and the return trip in detail — including the cases where the bus is genuinely the right call.
By taxi or private transfer: for the narrow case
A taxi covers the 35 km in about 45 minutes and solves the parking problem, but you are paying for two journeys and, unless you arrange a wait, you have no way back except a return booking. It makes sense mainly for a group with mobility constraints who want a viewpoint stop rather than the climb, or for anyone whose day has collapsed and who needs the site in the next two hours.
A private tour costs more but does more: hotel pickup, a driver-guide, a flexible route and the whole coast rather than one stop. If a taxi is where your thinking has landed, compare the private tours before booking one — from four people up the numbers are often closer than they look.
By guided tour: the option that removes the reservation problem
This is the honest case for the tours on this site, and it is narrower than the marketing suggests. A seat costs $63 to $94; a bus fare costs a few euros. What the seat actually buys is the elimination of three separate failure modes — the timed slot, the parking, and the weekday-only shuttle — plus a guide, and on most itineraries two or three more stops in the Urdaibai reserve.
The departures split cleanly by shape. The six-hour Mundaka and Gernika trip is the cheapest complete itinerary at $63 and includes the entry ticket. The nine-hour Bermeo route builds in a real lunch stop. The half-day walk gets you back to Bilbao before lunch with an eight-person cap. The four-hour coastal tour skips the staircase entirely and takes you to a viewpoint instead.
Check the inclusions rather than the title: not every tour bundles the access slot, and the private ones generally do not.
So which should you choose?
Book a tour if you are visiting in summer, at a weekend, on a tight schedule, or without a car — which covers most first-time visitors. Drive if you already have a car, want the wider coast in one day and can leave Bilbao early. Take the bus if it is a weekday, you are on a budget, and a long day with a margin for error appeals more than it costs.
Whichever you pick, sort the entry reservation first: read do you need tickets for Gaztelugatxe, and if a tour is looking likely, the which tour should you book guide narrows seven departures down to one.
