Astronomically at least, the solstice is the first day of summer. It’s the longest day of the year, when the sun reaches its highest elevation in the northern hemisphere. This year it’s on Friday, June 21.
The naturalists at Big Break Regional Shoreline in Oakley will celebrate it with a sunset walk from 7:30 to 9:30 p.m. It’s a chance to enjoy an evening exploration of the Delta, with lots of wildlife sightings possible.
Meet at the Big Break visitor center at 69 Big Break Road off Oakley’s Main Street. For information, call 888-327-2757, ext. 3050.
