Tour guide was excellent in providing lots of information about Bilbao, Gaztelugatxe, and Guggenheim. He was attentive and very kind. I did find it strange he didn't ask my kids' names or even ask where we were visiting from, but perhaps he was more focused on informing us during the tour. The tour itself was great. One thing to note is that the hike to Gaztelugatxe is on a dirt path for about an hour, so wear closed toed shoes. The hike then back up to the car is about 40min and quite steep and you climb at least 800+ vertical feet. On hot days, do not forget water, hat and a fan. We were dripping sweat at the end and our legs were shaky. We only had about 45min at Guggenheim - would've loved a little more time there. Overall it was a very good tour and would book again.

We enjoyed the experience a lot. Everything was well organized and the van was comfortable. Our guide, Alby, was very kind and attentive throughout the entire tour. He was always willing to answer questions and make sure the group enjoyed the experience. San Juan de Gaztelugatxe was what I liked the most. It is an impressive place and it is definitely worth visiting. The Guggenheim Museum is also a highly recommended stop. You just have to consider that the visit to the museum is quick; if your intention is to go through all the exhibitions calmly, it might be better to visit it on your own. But if what you are looking for is to get to know Bilbao and its main attractions in a single day, this tour is a very good option.

On the whole a very positive experience. On booking I did not realise what was involved in visiting Gaztelugatze, otherwise I wouldn’t have gone. Far too demanding on such a hot day. Guide was very accommodating, as others felt the same. Not enough free time in Bilbao . Guggenheim was a very good experience

We had to do a late minute cancel as bags were lost and we had nothing to wear. The company was not helpful with trying to rearrange or do a different tour. They just kept my $1000.
