Conditions guidance only. Cliffs are dangerous — never dig in or stand near them.
Check tide times locally and tell someone where you're going.
Safety page
Head north below the old alum quarries and search the rock pools and loose shale at low tide. Ammonites, belemnites and the odd sliver of true jet hide in the gravel — jet floats in a bucket of water, sea coal doesn't.
What fossils look like here
Ammonites hide inside rounded grey nodules — a coiled edge showing at the rim is the giveaway (take nodules home to split carefully; never hammer at the cliff). Jet is matt black, feather-light and warm to the touch; sea coal looks similar but heavier and dirtier. Belemnites are amber bullet-shaped rods. Free identification: Whitby Museum welcomes photo enquiries.
Allowed: Collecting loose fossils from the beach is long-established and accepted here.
Never allowed: No digging into the cliffs or hammering in-place rock on this SSSI coast; leave the jet seams alone — commercial jet digging has damaged this coast.
Important finds: Report significant finds to Whitby Museum.
Rules can change — check locally before you collect.
