Wadi Mujib is a dramatic gorge that descends to the Dead Sea shore from the Jordanian plateau, cutting through some of the most spectacular canyon scenery in the Middle East. The Royal Society for the Conservation of Nature (RSCN) manages a nature reserve here, and the Siq Trail — the main attraction — involves wading waist-deep through a narrow slot canyon against a current, scrambling over boulders, using ropes to pull yourself up small waterfalls, and eventually emerging into a natural pool at the head of the canyon.
The trail takes 3–4 hours round trip and requires a reasonable level of fitness and comfort with water. You will be wet for the entire route. The canyon walls tower above, and the sound of the water echoes. Life jackets are provided but not always necessary. The approach by swimming/wading with no gear except a life jacket and shoes is genuinely exhilarating.
The wadi is also one of the last habitats in Jordan for the Nubian ibex, and the reserve includes dry, trail-accessible sections of the canyon rim for walking with views. The entry gate is on the Dead Sea highway about 25 km south of the main resort strip, and the RSCN operates a simple guesthouse. Tickets must be purchased at the gate. The trail is seasonal — typically open March to October, closed during flash flood risk periods.
