Outdoor living

The Parker River National Wildlife Refuge’s fifth annual event this weekend has a simple message: “Let’s Go Outside.”

On Saturday from 10 a.m. to 3 p.m., adults and children alike are invited to try out a variety of activities, including kayaking, surf fishing, archery, nature and wildlife photography, and bird-watching — all for free.

There will also be hands-on crafts, a special station focused on the monarch butterfly and a display of tide pool critters.

Participants are encouraged to start at the visitors center, 6 Plum Island Turnpike, Newburyport.

Horse sense

New England Equine Rescue — North will host an open house at its West Newbury barn this Saturday.

From 11 a.m. to 2 p.m., visitors can explore the 52 Ash St. facility, meet rescued animals, and learn about the nonprofit’s mission of rehabilitating and rehoming horses and donkeys in need.

The family-friendly celebration will feature crafts, pony rides and live music. Food and drinks will be for sale, along with tack merchandise.

Admission is free, but donations are appreciated.
