We’re talking about the cosmos flower sea at Dongsha Lake Park in Hangzhou. Currently, the 30,000-square-meter cosmos flower sea is in full bloom. Looking out, the cosmos flowers look like little fairies you can almost touch, showing off their unique charm—perfect for photography, family outings, and camping!

What many don’t know is that Dongsha Lake Park in Hangzhou is a newly developed urban ecological waterfront park covering a water area of 335,000 square meters. It officially opened on April 28, 2025, featuring camping areas, a water sports center, a family playground, and many other functional zones. With a 2.5-kilometer lakeside greenway, a Smart Valley themed light show, over 3,000 trees, and more than 50 species of wetland plants, it’s truly an “urban wild park” and a modern urban complex integrating production, commerce, park, and residence!

Visiting Dongsha Lake Park in autumn, the first thing you’ll notice is the fresh air and the wide lake. Around the lake are winding greenways and many hidden photo spots full of surprises and comfort!

For first-time visitors, here’s a recommended route:

Subway Line 7 “Qicheng Road” Exit C — Pinyou Street — Dongsha Lake Park East Gate — Greenway — Lake Heart Island — Bridge Tunnel Coffee Camp — Cosmos Flower Sea — Water Sports Center — Wild Art Corridor — Yunfan Bridge — Return/Loop Trail — Love Island — Viewing Platform — Dongsha Lake Park East Gate

This full loop offers a 360-degree, unobstructed view of the “Little Sailimu Lake” scenery and the cosmos flower sea. It’s perfect for walking, family outings, cycling, or just daydreaming. It’s especially great for photography, family fun, and camping. Highlights include:

Photography: The autumn cosmos flower sea at Dongsha Lake Park is perfectly presented, with clusters of flowers glowing in the sunset, making it an ideal spot for landscape, portrait, video, or artistic shots!

Family Fun: Playing in the cosmos flower sea offers many fun activities for kids, including riding a small train around the lake, parent-child kayaking, tandem biking through the flower sea, and water sports at the Mairang Center, easily meeting various family needs!

Camping: Not far from the cosmos flower sea is the Bridge Tunnel Coffee Camp, where you can fish and catch shrimp while enjoying panoramic views of Dongsha Lake—a truly wonderful experience!

Uncle Shuai thinks the autumn cosmos flower sea in Hangzhou is absolutely amazing, featuring five classic photo spots: “Dongsha Lake Shore,” “Colorful Chairs,” “Internet-famous Swing,” “Mairang Coffee,” and “Yunfan Bridge.” There are also tandem bikes, single paddleboards, and a water sports center, making it a very comfortable autumn destination!

However, Dongsha Lake Park has very few commercial facilities, so it’s recommended to bring your own water and food for a more enjoyable visit!

Transportation:

By car: Navigate to “Smart Valley - Underground Parking Lot” station, park, and walk 5 minutes to “Yunfan Bridge,” which is an 8-minute walk from the flower sea.

By public transit: Take Subway Line 7 to “Qicheng Road” Exit C, then walk 15 minutes along Pinyou Street to the cosmos flower sea.
