Sermenza; the upper section above the lake is a core drop section, needing good water for granite slide & drop fun. The middle section is more boulder rapids and canyon constrictions with continued difficulties throughout. The lower section, has easier sport, with 2 canyons, the first more open with smaller drops and the last more compact and tight with a committing entry rapid.
Egua; the 'bonbon' of the area, the Egua is possibily the steepest Class IV pool drop you'll love to run!
