Pima Air & Space Museum and the AMARG Boneyard This Memorial Day Weekend: 80 Acres, Six Indoor Hangars, More Than 425 Aircraft on Valencia Road — and the Davis-Monthan Storage Yard Tour That Only Runs From the Museum

Memorial Day weekend, May 23 to 25, 2026, is the moment in the Tucson calendar when the long-weekend traffic at the city's outdoor parks meets the first stretch of true late-May heat — and the Pima Air & Space Museum at 6000 East Valencia Road is one of the few large-format attractions in the metro that is mostly indoors, mostly climate-controlled, and built around the military-aviation history the holiday was made for. Per the Pima Air & Space Museum's own visitor pages, the 309th AMARG Boneyard Bus Tour reservation page, the Davis-Monthan Air Force Base 309th Aerospace Maintenance and Regeneration Group public-affairs materials, Visit Tucson, the Arizona Daily Star (tucson.com), the Tucson Sentinel, the City of Tucson, and the Sun Tran route map, the museum's 80-acre campus holds more than 425 aircraft across six indoor hangars and the outdoor display yards; admission runs $19.50 for adults, $16.75 for seniors and active military, $12.75 for children ages 5 to 12, and free for children under 5; the museum opens daily at 9 a.m. with summer closing in the mid-afternoon; and the AMARG Boneyard bus tour is the only public-facing way to access the Davis-Monthan storage yard, running on weekdays only with valid government-issued photo ID required at base entry. Here is the May 20, 2026 sourced walk-through.
