As the hot summer days begin, finding a cool destination with crystal-clear water and unspoiled nature is the perfect excuse to escape the heat and hustle of Tehran. Fortunately, within a short distance from the capital, there are beautiful rivers, waterfalls, and gorges that can provide a refreshing and memorable day trip. Here are seven attractive destinations for swimming, water play, and nature exploration around Tehran.
1. Laloon Gorge (Lalan) – Fasham
Laloon Gorge is one of the most popular hiking destinations around Tehran, located in the heart of the Alborz Mountains near Fasham. The rushing Laloon River flows throughout the valley, creating numerous natural pools that are ideal for cooling off and enjoying the water during hot summer days. The lush landscape, abundant springs, and refreshing mountain air have made this area a favorite weekend getaway for Tehran residents.
At the end of the trail lies Laloon Waterfall, which cascades from a height of approximately 20 meters (66 feet). Many visitors walk through sections of the river and enjoy the refreshing water along the way. The best time to visit is from late spring to early autumn.

Baragh Jahan Waterfall is located in the upper elevations above the village, and the trail leading to it features several natural pools and scenic spots perfect for relaxing by the water.
The cool climate, soothing sound of flowing water, and stunning mountain views make this destination especially popular during summer. Although the pools are not very deep, they are perfect for splashing around and cooling off on hot days.
