Short canyon hikes, cliffside walkways and a calm reservoir combine on this day trip from Valencia. Spend a shaded 1.5-hour walk along the Guadalaviar then swap boots for a kayak or SUP to explore Arquillo de San Blas.

The trail begins where the hamlet of San Blas spills into rock and water: limestone walls slope down to a narrow ribbon of the Guadalaviar that dares you to follow it. Shade from riparian pines cools the first steps as the canyon tightens and wooden walkways cling to the cliffs, a route cut by water and time.

Wildlife
History
The Guadalaviar rises in the high Montes Universales; historically the river’s course shaped local villages and the reservoir now stores mountain water that eventually feeds the Turia toward Valencia.
Conservation
Follow leave-no-trace practices—avoid disturbing banks where riparian plants stabilize the soil and rinse gear to prevent spreading invasive species between water bodies.

Sturdy, grippy shoes
Boardwalks and river rocks can be slippery—trail runners or trekking shoes with a good sole keep you steady on wet sections.
Hydration & snacks
Carry at least 1.5 L of water and a salty snack; shade is intermittent and the water activities can leave you hungrier than expected.
Sun timing
Start early in summer or plan late-afternoon water time to avoid the peak heat and get softer canyon light for photos.
Secure valuables
Bring a dry bag or leave electronics locked in the transport—boat time and swimming make pockets risky.
Trail shoes or sturdy trainers
Grip and ankle support for rocky paths and damp boardwalks.
Dry bag or waterproof phone case
Keeps valuables dry during kayaking, SUP, or swimming.
Reusable water bottle (1.5 L+)
Hydration is important—there's limited shade on exposed sections.
summer
Light windbreaker or quick-dry layers
Evenings and canyon shade can be cool; a thin layer helps after water activities.
