Since opening 2015, the New Canaan Land Trust’s Firefly Sanctuary has grown in popularity. In an effort to protect the natural resources at the Sanctuary, including the firefly population itself, we will be requiring advanced registration for admittance into the sanctuary during the peak firefly viewing season of June 27 through July 10.
Registration for the peak viewing season is full. Visitors are welcome to visit the Firefly Sanctuary without registering after July 10. While not the “peak” of the firefly season, the fireflies will still be out through mid/late July as the firefly mating season tapers off.
Location: Parking for the Firefly Sanctuary is located across from 33 Sleepy Hollow Road. Please park on the grassy pull-off, near the white welcome sign for the sanctuary. The fireflies live in a large meadow located approximately 0.25 miles up the trail.
Timing: Please plan to arrive by 8:30pm. Visitors will not be admitted into the Firefly Sanctuary after 8:45, in an effort to reduce light pollution from flashlights (more on that below). You are welcome to stay and enjoy the fireflies until 10:30.
Limiting Light Pollution: Fireflies communicate using light, so any artificial light can confuse and disorient the fireflies during this critical mating period. As such, we ask that you minimize use of any lights during your time at the sanctuary. By arriving at 8:30, you will be able to make it up to the viewing area without the need for a flashlight. While viewing fireflies, please limit phone use and do not take flash photos. We will provide you with a special red-filtered flashlight for your walk back to the car.
Using Insect Repellent Responsibly: Fireflies are also affected by insect repellent, so we ask that you apply bug spray while at the parking area. No insect repellents may be applied at the viewing area. We encourage the use of natural insect repellents.
What Else to Wear/Bring: We strongly encourage visitors to wear a long sleeve shirt, long pants, and a hat, as mosquitos can be abundant. Sturdy shoes are also encouraged, as the woodland trail is rocky and uneven in places. We have a number of benches for our visitors, but you are welcome to bring a lawn chair, should you want to sit away from the main seating area. There are no facilities at the Firefly Sanctuary.
