Hessel Marsh, a seasonal symphony of nature’s beauty
Hessel Marsh is a natural wonder nestled in Chalous, Mazandaran Province, renowned for its vibrant display of algae in hues of green, pink, and red that change with the seasons. The term hessel signifies both stagnant water and a seasonal water reservoir. Situated south of Talaju and Sinava village, this enchanting marsh lies 10 kilometers southwest of Chalous and 15 kilometers northwest of Marzanabad, deep within the renowned Mash’al Forest.
A picturesque oasis
Hessel Marsh is a hidden gem, cocooned within a lush forest adorned with majestic trees and veiled in mystery. As you traverse the forest’s winding paths, the air takes on a tangy quality, signaling your approach to this captivating destination.
Upon reaching Hessel Marsh, you’ll be greeted by a spectacle of trees and plants encircling it like precious pearls, enhancing its allure. Perched at an elevation of 250 meters above sea level, the marsh’s size fluctuates, reaching less than a hectare at its fullest. Studies conducted in 1996 estimated its area to be approximately 3,800 square meters, adding to its mystique and charm.
The waters of Hessel Marsh stir from its depths and core, untouched by any flowing rivers or streams. Towards the marsh’s lower extremity, an ancient tree shelters a bubbling spring, seamlessly merging with the marsh’s essence. This subaqueous spring is an integral part of Hessel Marsh. On its eastern flank, a channel meanders, occasionally carrying excess water towards the Chalous Valley when overflow occurs. The primary source of water for Hessel Marsh stems from seasonal rains commencing in late autumn and persisting until mid-spring. Some years witness a decline in water levels, resulting in a significant decrease in the marsh’s water capacity.

The surface remains undisturbed, devoid of waves or ripples, adorned with a lush carpet of algae, reaching a depth of half a centimeter, leaving no gaps untouched. These algae exhibit varying hues, transitioning from green in shaded areas to orange and finally a vibrant red in the sunlight, casting a breathtaking spectacle.
Vegetation
Hesel Marsh was once a habitat for numerous animals and creatures; however, with the disruption of the marsh ecosystem, these species are no longer seen or are less abundant. Perhaps the reason for this is the opening of the area to tourists by building a road in the heart of the forest.
Turtles, lizards, and leeches were once common inhabitants of Hessel Marsh, yet their presence has diminished over time. While fish do not populate the marsh, it offers an ideal habitat for amphibians. Historically, the region also served as a watering spot for larger animals like lynxes and leopards. Before the area’s designation as a national park, the Hessel Marsh surroundings were utilized as grazing lands by the villagers of Sinava and Talaju. The marsh’s vegetation cover includes a variety of trees such as oak, walnut, elm, ash, and maple, as well as fruit-bearing trees like wild apple, wild grape, fig, and pomegranate, along with an assortment of medicinal plants like chamomile and fennel.
