✨ AI-Enhanced Insights

Castle Airport (MER/KMER) is a public airport on the site of the former Castle Air Force Base in Merced County, California, about 8 miles northwest of Merced. It opened for civilian use after the base closed in 1995 and retains a long runway and military aviation heritage. The airport is also home to the Castle Air Museum, which displays historic military aircraft.

💡 Local Tip
Aviation visitors should allow extra time for the Castle Air Museum—its outdoor aircraft displays are best explored in cooler morning hours, and the museum sometimes hosts special open-cockpit or event days worth checking before you go.
🚖 Getting There

By car, reach Castle Airport from CA-99 via the Atwater/Merced area, then follow local roads west toward the former base; the drive from Merced takes about 15-20 minutes. Public transit does not provide direct terminal service, so plan on a taxi, rideshare, rental car, or prearranged pickup. If you are flying in, confirm ground transportation in advance because on-demand options can be sparse.
