On a one-day trip to Tangeh Dar Nowshahr, you can swim in the clear waters of the Karkorud River, walk along forest paths, and enjoy river-trekking. Tangeh Dar is a hidden gem in the heart of Mazandaran’s lush forests; its unique beauty provides nature lovers with an exciting mix of adventure and tranquility. Traveling along a river corridor framed by forest and towering rock walls creates a distinctive and thrilling experience — part adventure, part peace.
If you're looking for a quick but memorable trip, Tangeh Dar, with its water-hiking trails and untouched scenery, is a perfect choice. Bring water-walking shoes and comfortable clothing, and you'll be ready to enjoy the landscape safely. Below, you'll find detailed information to help plan a one-day visit to Tangeh Dar.
Tangeh Dar in Nowshahr — often dubbed the “Iranian Amazon” — is an ideal one-day destination because of its convenient distance from cities such as Tehran and Nowshahr. The gorge’s beautiful nature and fresh air provide a unique escape from urban crowds and allow visitors to enjoy a different kind of day in the green mountains of Mazandaran.
The best time to visit Tangeh Dar is the warm season, roughly from mid-June to early September. During this period the weather is usually sunny and stable with moderate temperatures, and the river depth is suitable for walking the waterway.
In spring the river’s depth can be high and frequent rains increase slipperiness and the risk of sudden rises in water level, making passage hazardous. Autumn and winter are also unsuitable because of cold conditions and the higher likelihood of heavy rain and snow.
Depart Tehran early for the village of Kushk-Sara so you have ample time to explore the gorge and the surrounding nature. After arriving at the village parking area and paying any entry fee, put on proper footwear.
The path to Tangeh Dar from the Karkorud River is approximately 1.5 miles, so plan for three to four miles of walking through water for a round trip. The river is shallow at the beginning — usually up to knee level — but narrows and deepens as the walls close in. When the gorge tightens, the water becomes deeper; in these sections, travel with a group and use a rope in risky areas. Along the way, enjoy views of the forested Khanikan, along with rock vegetation like moss and valerian, and other plants. In the deeper parts, you'll find chances to swim in clear, cool water; if you're not a confident swimmer, steer clear of those areas.
During the route you can rest, have snacks or lunch and take photographs while enjoying the peace of the wild. At the end of the gorge there is a very beautiful waterfall; shorter cascades appear along the way as well. After absorbing the natural scene, return either via the gorge route or by the parallel forest path back to the parking area. Completing the whole route takes around three to four hours, though you can choose to do a shorter section and still enjoy the area.

Mid-week visits are recommended — weekend crowds can stir the river and make the water murky.
Wear waterproof shoes or trekking sandals; plastic flip-flops are not suitable for river passages.
Pack light: an extra set of clothes, a small towel, a rubbish bag, a water bottle and light snacks. Avoid carrying heavy or unnecessary items. Some shops at the trailhead sell basic supplies and footwear if you lack equipment.
Travel in a group and remain on the main route. Rocks inside the river can be slippery — use caution.
Do not leave litter on the trail; respect the environment and do not break branches or harm plants.
Protect cameras, phones and electronics with waterproof covers or dry bags.
Due to the depth and uneven ground, the gorge is not suitable for children, the elderly, people with limited mobility or non-swimmers — a moderate level of fitness is required.
