Through the tireless efforts of many members of and contributors from the Basque communities in Idaho and the Western US, this is a very special place to BEGIN TO LEARN some elements of the worldwide Basque culture.  The exhibits have been changed this past summer and the new direction is emphasizing the Idaho Basque experience using video storytelling and some modernized media.  It includes many personal stories of community.
The Basque Block events and historical preservation are continuing through the commitment of community volunteers from the memberships of the Basque Museum & Cultural Center and the Basque Center Basque Foundation (Euskaldunak).
The hours of operation may not fit the desired times of a visitor to Boise so it is strongly advised to check their website at https://basquemuseum.eus/visit/ prior to planning your visit.  If you are interested in seeing the museum, the 160 year old Cyrus Jacobs-Uberuaga Boarding House and maybe eating some Basque culinary delights, a one hour parking meter payment will not be sufficient.  There are three nearby ParkBoi parking structures where the first hour is not charged and any other hours are fairly priced.  If you have unruly children or your ability to walk & climb is impaired, you would be best served by connecting to the virtual tour.  https://basquemuseum.eus/see/virtual-exhibits/virtual-tour/
The beautiful handball court in the 108 year old Anduiza Boarding House (now a commercial building) is not open to the general public but is reserved for Basque handball clubs to use.  Using the virtual tour from the Basque Museum website, you can view an actual game being played.

In addition to the museum and the historical buildings maintained in the area there is Boiseko Ikastol - the only preschool teaching Euskara in the United States!  It is open to Basque and non-Basque students, alike.  Also, adult Euskara language classes are frequently organized at the Museum.  
Inside the museum is a very well-stocked gift shop that is very responsive to special orders.  Apparel, home items, gifts, souvenirs, Basque txapala (cap), flags, bota bags, music and books are readily available.  
During a recent visit, the Museum rates are: Adults $5; Seniors (65+) $4; Student $4; Children (6-12) $3 with Children (5 & under) Free.  In addition, there are active duty military discounts and current teacher discounts.  Frequently, there are Free days in conjunction with the "first Thursday" program of the City of Boise.  The paid admisssion is good for entrance to the Uberuaga Boarding House, but between Sept to June it is only open on Saturdays with limited hours.  Again, it is best to check the website before going.
It is truly sad to read reviews from Yelpers who expend their sick attitudes demeaning the efforts of the volunteers of this valuable community and cultural resource.  One review comes from a person who has no other reviews or friends.  Experienced Yelpers know this vindictive type.  Another sick review comes from a person who disclosed in multiple other 1-star reviews that she is being treated for a serious psychiatric condition in her home state of CA.  Perhaps these sour people who come to the Museum expecting to be given a free, individual, tailored tutorial on all-there-is-to-know about the Basque history & culture compacted into the 30 minutes before their parking meter runs out will find happiness in some other aspect of their life.  Doubtful, but forever optimistic.
