This route covers 3km return.It involves around 60m of cumulative elevation gain.
The route reaches roughly 120m at its highest point.
Technically, the St Nectan's Glen Waterfall standard trail is a scramble. The walk is generally straightforward, with varying conditions depending on the immediate environment.
Overview
Technical Summary
St Nectan's Glen is an enchanting, atmospheric woodland valley deeply cut into the Cornish slate near Tintagel. This short, easy 1.
The Kieve Hole. The 'X-Factor' is the unique geological formation of the main waterfall. The river physically drops into a plunged pool (known as the 'Kieve') and then sustainedly punches straight through a perfectly round natural hole in the slate wall, pouring out into a secondary basin. Standing thigh-deep in the water wearing wellies (provided at the site) to look directly through the rock window is surreal and completely magical.
Hazard Assessment
The path follows the riverbank closely. It is constantly damp, littered with smooth slate fragments, and heavily crisscrossed with massive, exposed tree roots.
The path is safe, but entering the waterfall pool area after very heavy rain is dangerous due to the immense volume of water blasting through the rock.
Route Summary
This is a scenic and highly accessible route.Check the local forecast and plan your schedule to allow ample time to enjoy the views.
Stage Breakdowns
Trethevy Car Park to the Woods
Leaving the tiny hamlet of Trethevy, entering the deep shade of the ancient woodland running alongside the Trevillet River.
The Waterfall and Kieve
Arriving at the visitor center, descending to the plunge pool basin to view the spectacular river blasting through the rock hole.
The Return Loop
A gentle walk back, either retracing steps through the glen or following a slightly higher woodland track back to Trethevy.

Technical Profile
Vertical Ascent Profile
Very easy and flat. The path gradually ascends upstream alongside the river. There is a small, steep set of steps leading up to the visitor center/café area immediately before descending a short metal staircase into the waterfall plunge pool.
Terrain Characteristics
Scramble terrain (Class 2) — involves fixed-rope sections or often required hand-use on steep terrain.
The physical demand is defined by the 3km distance and local environmental conditions rather than vertical gain.

This profile uses the HikeMetrics v1.0 risk matrix, prioritizing environmental stress and movement complexity over simple elevation metrics.
Technical Specs
Access & Logistics
Regulations
You should pay to access the metal staircase leading down into the plunge pool basin.
Seasonality
Best visited immediately after heavy rain (autumn/spring) to see the waterfall at its most ferocious. Summer is wildly busy. Regulations change; verify with the official park or local authority before departure.

Route Questions
Do I have to pay to see the waterfall?
Yes. The woodland walk is free, but the entrance to the waterfall basin and the walkway down to it is privately owned and requires an admission ticket.
Do permit rules stay constant year-round?
Not always. Permit and guide requirements can change by season and region. Verify the latest rules with the official park office or local authority before departure.
What is the safest start-time strategy?
Start early and plan to clear exposed sections before midday. This reduces heat, storm, and visibility risk on most mountain routes.
How much water capacity is usually needed?
For exposed hiking days, carrying 2-3 liters is common. Increase capacity when refill reliability is low or temperatures are high.
Is mobile signal reliable on route?
Coverage is often patchy outside towns and major valleys. Treat phones as secondary tools and carry offline navigation resources.
