2.5-3 hours from Marrakech, the Ouzoud Waterfalls (110m) are Morocco's tallest, tumbling into the El Abid River gorge, often with rainbows visible.
Things to do
Marked paths to the base of the falls, boat rides, spotting Barbary macaque monkeys in olive trees, swimming in summer in natural pools.
Practical tips
Sturdy shoes recommended, paths can be slippery. Plan a full day. Local guides offer their services at the top. Riad Dar Kawkawa arranges it at +212 661 13 22 74.
