🦋 Monarch Tagging Weekend returns September 12 & 13!
Each fall, Monarch butterflies travel more than 3,000 km from Ontario to their overwintering grounds in the mountains of central Mexico. Join us for a weekend celebrating their incredible migration and learn how you can help support this species at risk.
🌱 Take Home Common Milkweed Seeds
Help support Monarchs at home! Visiting groups can take home a complimentary packet of Common Milkweed seeds with simple planting instructions. Milkweed is the only host plant Monarch caterpillars eat and plays an important role in their life cycle.
While supplies last. Limit one seed packet per visiting group.
🦋 Monarch Butterfly Releases
Watch Monarchs take flight as they begin their migration to Mexico. Releases take place outdoors at 11:30 am, 1:30 pm & 3:30 pm, weather permitting.

🎨 Monarch Crafts & Colouring
