The Kourtaliotiko Gorge cuts through the mountains of southern Rethymno, a deep green canyon where the Kourtaliotis river tumbles down toward the Libyan Sea. Many travellers see the gorge only from the road, stopping at the viewpoint above the Great Waterfall, but river trekking takes you into the water and the canyon itself. The route follows the stream bed between steep rock walls hung with plane trees and oleander, with pools you wade through, small cascades and boulders to scramble over. In a few places the gorge narrows so much that the walls seem to close overhead. Because the trek follows the river, the experience is cooler and quieter than a road tour, and the gorge changes character through the year: in spring the water is higher and more dramatic, while in summer it is a refreshing way to escape the heat. A guided shared trek is a good option for people who like the outdoors but want expert help with route-finding and safety.
How it works
A guide leads a shared group, usually of mixed ages and abilities, along the river for around five hours, including the transfer and breaks. Helmets, special shoes and sometimes wetsuits may be provided, and you usually meet at a base near the gorge or at an agreed pick-up point. Check what equipment is included, the minimum age and the level of fitness expected when you book. The activity runs in the warmer months and may be cancelled when water levels are high after heavy rain.
What to expect
You walk, wade and sometimes swim through cool water, so you will be wet for much of the time. The rocks can be slippery, and the guide will show you safe footing and when to use handholds. The pace is steady with plenty of stops for photos, a swim and a snack.
It is a physical activity but not a technical one, and most reasonably fit adults and teenagers manage it. Bring swimwear, a towel, dry clothes, sun cream, water and a plastic bag for your phone or camera, and leave valuables in the vehicle.
Making the most of it
Combine the trek with Preveli Beach, which is only a short drive away, and with a lunch in one of the villages of the south. If you are travelling with children, ask about the minimum age and the water depth on the route. People with knee or balance problems should choose a gentler walk instead. If you prefer a more adventurous option, ask about canyoning at the same gorge. Pair this with a calm evening in Rethymno afterwards, when the Venetian harbour lights make a pleasant place to unwind.
Good to know
The gorge is a protected natural area, and the waterfalls near the road viewpoint are popular for photographs even for those who do not trek. Water temperature stays cool even in summer, so a thin wetsuit or extra layers can make the trek more pleasant, and many operators provide them.
Leave jewellery and electronics in the vehicle, and use a waterproof bag for your phone. The activity depends on water levels, so ask the operator about conditions on the day and be prepared for a change of plan if there has been heavy rain in the mountains.

Good questions
How fit do I need to be for river trekking?+
A moderate level of fitness is enough. You will walk on uneven ground and wade through cool water, but the route is guided and the pace is relaxed.
What should I wear?+
Swimwear under quick-drying clothes and shoes that can get wet. Equipment such as helmets and special footwear may be provided, so check when you book.
Is it suitable for children?+
Often yes for active older children, but check the minimum age and the depth of the water on the route. Parents should judge their child confidence in water.
Can I do it in winter?+
The activity runs mainly in the warm months, because the water is cold and levels can be high after rain. Check the season when you book.
Where is the Kourtaliotiko Gorge?+
It lies in southern Rethymno, a short drive from Preveli Beach, and is reached by road from Rethymno in about an hour.
