Each spring during the first warm rainy night after the equinox, hundreds of amphibians move from underground lairs to vernal pools. To find out when Baltimore Woods will attempt to observe this migration at Labrador Hollow, watch for alerts on our website, or sign up online to be put on our alert list. Bring a flashlight and dress for the weather. Keep an eye on your email for updates and alerts. Program for ages 5 and up.
