Celebrate Earth Day with your eyes to the sky and your feet on the trail!
Join us for a nature-loving adventure where we’ll spot local birds and get to know the trees that make our landscape thrive. Whether you’re a seasoned birder, a curious tree-hugger, or just here for a good walk outside, this is a fun, hands-on way to connect with the wild world around you.
Bring your curiosity, your binoculars (if you have them), and your love for the planet—let’s explore, learn, and celebrate Earth Day together, one bird call and leaf at a time!
All ages and experience levels, but geared towards beginners. Trail is 2.7 miles on flat, grassy path. May be difficult for strollers and wheelchairs and people with mobility issues. Bug spray needed as ticks and mosquitos will be out (but not biting flies)

The Sierra Club is launching Sierra Sessions just in time for the Delaware Chapter's 35th anniversary! Join us at Blue Ball Barn for a streamed concert designed to engage communities and capture the public’s imagination around environmental action. Our event will spotlight talented singer-songwriters who will perform a 2–3 song set, sharing the personal stories and inspirations behind their music — and their reflections on nature, climate, and the environment.
We will have vendors, a food truck (or two), a local brewery serving guests, great music, and great fun!!!
The event is free for members. But, if you are not already a member, you can join today by buying the “Become a Member Now” ticket, and we will use the cost of your ticket to get you a membership!

Every year, we gather in Legislative Hall in Dover and meet with legislators about issues that matter to our members and supporters at the Sierra Club Delaware Chapter. This year, the two big things on the table are holding data centers accountable and protecting our wetlands. With the theme "Protect Us All, From Big To Small", we are asking legislators to focus on the bigger picture and to address everything from big data center threats to the smaller creatures in our sensitive wetlands.
Participants will be meeting with legislators in groups and don't have to be experts on the bills to participate. Your role is to show decision makers that Delawareans care about these issues and share your personal story!

We want to call special attention to our fight against the mega data center proposed for Delaware City, which would harm its vulnerable neighbors, impact crucial wetlands, and cause electricity bills to skyrocket for Delaware families.
You can learn more about the data center here and take action here.
Would you like to get even more involved? We are currently organizing canvassing sessions in the most impacted communities directly across from the proposed data center. Anybody interested in canvassing should contact Marissa at marissa.mcclenton@sierraclub.org.
