The Hoffler Creek Wildlife Preserve Foundation will have a Sweetheart Full Moon Walk from 7 to 9 p.m. this Saturday, at the 142-acre preserve on the edge of Portsmouth.

The event is strictly for couples 21 and older.

A full moon will be shining overhead as couples walk the preserve’s trails to begin the evening. They will then be invited back to the headquarters building for wine, cider, cheese, chocolates and other pleasantries by a warm fire.

Advance registration is required, and the deadline is noon Saturday. Couples registrations are $25 for HCWPF members, and $35 for non-members.

Admittance will not be allowed after 7 p.m., so it’s recommended that attendees arrive by 6:45 p.m.

The foundation organized this moonlit stroll to offer couples a unique way to celebrate Valentine’s Day this year.

“Not everybody is into fighting to get into the restaurants,” HCWPF Executive Director Helen Kuhns said. “Some are excited to try and do something a little different.”

Kuhns said the 45-minute stroll through Hoffler Creek’s preserve is perfect for couples that are a little “outdoorsy.” She also noted that the preserve comes “awake” after dark.

“We have animals that come out, and you might hear our great horned owls in the woods, or catch a glimpse of a flying squirrel,” Kuhns said. “There’s an excitement edge to it.”

The foundation recommends that couples be prepared for cold weather in the evening with hats, coats and gloves. If the conditions are too bitter, then the walk will be postponed until Sunday.

Couples are allowed to bring small flashlights, but no strong or intense lights. Kuhns said people can see pretty well at night in the preserve without them, especially this weekend with the full moon.

Participants will get “a new perspective” during this moonlit evening in the preserve, providing a fresh approach to Valentine’s Day romance this year, she added.

“It’s an opportunity to share the preserve at night, with a romantic walk on a wooded trail in the moonlight,” Kuhn said.
