Karacabey Floodplain Forest & Water Lily Lake: Turkey's 2nd Largest Flooded Forest
1. Essential Facts and Quick Visitor Summary
Karacabey Floodplain Forest (Longoz), spanning over 7,300 hectares across the Kocaçay Delta where freshwater meets the Sea of Marmara, is Turkey's second-largest flooded forest ecosystem after İğneada. Famed for monumental ash trees rising straight out of flooded waters, tens of thousands of floating white water lilies, free-roaming wild horses (yılkı), and over 250 recorded bird species, it offers an untamed Amazonian atmosphere in the heart of Bursa province.
Submerged beneath mineral-rich waters in winter and spring, the forest transitions in summer into a verdant botanical paradise centered on Water Lily Lake (Nilüfer Gölü). Visitors experience wooden boardwalks, observation towers, canoe trips, and flat-bottomed boat safaris among floating water blossoms.

2. The Science of Longoz (Floodplain) Ecosystems
Floodplains form when coastal dunes block river mouths, causing seasonal floods to submerge forest floors for months. In Karacabey, narrow-leaved ash (Fraxinus angustifolia), alders, and willows have evolved deep aerial root systems to thrive submerged in river silt, supporting an extraordinary web of aquatic and avian biodiversity.
3. Water Lily Lake (Nilüfer Gölü) & Boat Tours
Hidden in the forest interior, Nilüfer Gölü transforms each summer into a carpet of white (Nymphaea alba) and yellow water lilies. Guided tours aboard silent rowboats glide through channels of blossoms, offering world-class reflections and photography.
Insider Tip
"Paddle through flooded ash trees and white lily fields by renting a canoe in May-June. Don't forget to take binoculars with you when you go to the bird observation tower."

What exactly is a 'longoz' (floodplain forest)?

Can visitors take boat trips on Water Lily Lake?
Yes, guided rowboat and canoe tours navigate silently through the water lily channels, taking about 30 to 45 minutes.
Is picking water lilies permitted?
