Bentonville in June

March through May brings perfect biking weather – 70s during the day, cool mornings, minimal humidity. Fall (September through November) offers the same comfortable temps plus changing leaves in the Ozark hills. Summer gets sticky. We're talking 90+ degrees with Arkansas humidity that makes you question your life choices. But summer also means the mountain biking trails stay open later, and Crystal Bridges' outdoor sculpture trail is accessible all day. Winter can surprise you – one day it's 60 degrees, the next it's icing over. The museum stays warm year-round, though, and indoor activities multiply when the weather turns.
