How We Make This Guide
Every guide on this site is built from direct field experience on the Sussex Heritage Coast. This page sets out exactly how we research, write, verify, and correct it.

First-Hand, Field-Verified Content
SevenSisters.co.uk has documented the Seven Sisters and the wider Sussex Heritage Coast through direct field work since 2019. Every guide is written from first-hand experience: routes walked, tides timed, parking observed, and conditions photographed on the ground.
The principle is simple — if we have not stood on that cliff in those conditions, we do not write about it as though we have.
- ✓ 100% original photography. No stock images, no borrowed tourism-board shots. The cliffs on this site look like the cliffs you will actually see.
- ✓ Field observation over desk research. Over 200 logged cliff walks across every season inform the practical detail — tide windows, path conditions, and the logistics most travel sites leave out.
- ✓ One named author. Guides are written and edited by Alen Marrick, a Seaford-based coastal writer and photographer — never anonymous or ghost-written.
Independence Charter
SevenSisters.co.uk is an independent visitor guide. We are not affiliated with, funded by, or endorsed by the National Trust, the South Downs National Park Authority, Natural England, or any government body. We receive zero financial underwriting from the organisations that manage this coastline.
That independence is the point. It means our reviews of transport, parking, fees, facilities and services reflect what we actually found — not what an official partner would prefer us to say.
The site is funded by clearly marked affiliate links and display advertising. Commercial relationships never influence our recommendations. Full detail is in our Affiliate & Advertising Disclosure.
Our Policy on AI
We hold a strict line on generative AI, because the people reading this site make decisions about cliff edges, tides and weather based on what we publish.
We never use AI to
- ✗ Write or rewrite environmental, geological, or safety-critical guidance
- ✗ Generate first-hand experience, observations, or reviews
- ✗ Produce or alter any photography on this site
We may use AI for
- ✓ Technical script and structured-data (schema) diagnostics
- ✓ Spelling, grammar, and accessibility checks on human-written copy
- ✓ Cross-checking facts against authoritative sources before a human verifies them
In short: the words and images describing this coast are human-made, from the field. AI is a tool for code and quality control — never a substitute for being there.
Sourcing & Accuracy
First-hand observation drives the practical content. Where we state scientific, geological, or designation facts, we ground them in recognised authorities and link to them directly so readers can check the original source.
- • Geology — the British Geological Survey Lexicon of Named Rock Units (Seaford Chalk Formation)
- • Coastal erosion — the Environment Agency National Coastal Erosion Risk Map
- • Conservation status — Natural England and official gov.uk designation records
- • Tides — UK Hydrographic Office harmonic predictions for the nearest standard port (Newhaven)
Our full field-research process is documented on the Research Methodology page.
When We Get It Wrong
Coastlines change. Steps close, cafes change hours, paths get rerouted, and occasionally we make a mistake. When we do, we fix it openly and record substantive corrections in a public log.
See our Corrections & Updates policy, or report something that needs fixing via our contact page.
