The 6.5-kilometer walk along Barranco del Inferno turned out to be interesting and quite simple in terms of route. The main goal of the route is the La Cascada waterfall. The waterfall, of course, is not particularly impressive (we have seen bigger ones), but on the whole it is quite cute and photogenic ...
From practical advice:
1) online booking and purchase of tickets are mandatory;
2) before the trip at the appointed time, check your email - you may receive a letter about the cancellation and postponement of the tour due to the elevated temperature;
3) come to the opening, by 08.30., there will be a chance to walk two thirds of the route in the shade;
4) do not neglect the helmets that are issued at the beginning of the route after the briefing, in fact, as well as the briefing itself (conducted in Spanish and English);
5) do not forget about the water, a liter of water per tourist will be just right.
Well, something like that...
