A wooden bridge crosses Teatown Lake and leads to Wildflower Island, a two-acre space where more than 200 native plant species grow, nestled within Teatown Lake Reservation in Ossining, about 10 miles from downtown Peekskill. On Saturday, July 5, the site will open its gates for two scheduled tours—from 10 to 11 a.m. and from 1 to 2 p.m.—led by local naturalists. Attendance is limited to six people per group. Teatown is among the preserves with the greatest documented botanical diversity in Westchester.

Wildflower Island is explored on foot along trails and elevated wooden boardwalks, a kind of floating bridge. No boats are involved. The walk takes place entirely by foot along these planks that cross wetland zones and small sections of the lake. Over the course of the hour, guides highlight species such as trilliums, native orchids, ferns, and grasses, as well as the conservation methods that protect the island from deer overbrowsing and invasive species.

“The island seems small, but every single foot has something different to show. I was struck by the number of flowers I had never seen before,” said Beth Smith, a resident of Tarrytown, after her first visit. She believes the space is well managed and praises the reserve’s efforts not only to care for the environment but also to educate people on how to protect the ecosystem.

An important detail emphasized by those in charge of the site is that children are not permitted on the island. This is due to the nature of the tour and because the platforms surrounding and crossing the site may not be safe for minors. Conservation concerns also play a role in this rule, since many of the plant species are fragile, located very close to the boardwalks, and could be damaged if stepped on. However, other areas of the preserve and various activities are specifically designed for children, who are welcome at Teatown.

If there is heavy rain, the event may be canceled or rescheduled. Reservations can be made through Teatown’s website. Tickets cost 10 dollars for members of the conservation center and 15 dollars for non-members.

The guided tour will be held every Saturday through the end of September, with two sessions each day, and requires advance booking. Additionally, there is an option known as Open Gate Days, specific days when the island is open for self-guided visits only during limited hours, from 11 a.m. to 1 p.m. For more information, visitors can contact Teatown.
