Sure thing.
Scarborough's main bay has an excellent rocky shore that is often referred to as Holbeck. If you head down on to the beach from the arcades, the rocky area is to the right, about a 10 minute stroll across the beach to get to.
Holbeck is an excellent all-round rocky shore with a variety of organisms. It is moderately exposed and rockpools are either sand or pebble bottomed, but no muddy/silty conditions so sea potatoes, angular crabs, and other burying-in-the-mud organisms are largely absent. It is our favourite shore here though.
Scalby Mills is less exposed, and has a slightly different range of organisms. This area is particularly good for edible sea urchins at low tide. Last winter during a low tide of 0.6m we found over 50 of them at low tide. All of them good sizes too. Scalby is a little further north from Holbeck, past the Sealife centre.
Cornelian Bay is to the south of Holbeck, and is dangerous in that it can trap you very easily if you're not wary. Daytime low-tides only I think! Cornelian Bay is good though and apparently Bloody henry starfish are present there. We have not found one yet although we do not frequently visit Cornelian Bay as it is the furthest away (in Scarborough at least). We have found our only Lesser Weever fish here.
Finally there is Filey brigg, which I have only been to once while on a biology field trip, so I can't tell you much. However it is significantly different from the aforementioned sites. It features muddy/silty bottomed rockpools, and has one side which is very exposed, and one side that is sheltered. Mussel beds abound, so if you crack open a few you could find yourself a live pea crab! We are going to check Filey out more in spring 2010, and hopefully it will deliver a different range of organisms compared to the Scarborough sites.
Oh and finally, Holbeck is the best place for lobsters! We usually find at least one on each low tide trip. It is also worth sifting a net through the sand, and the algae on the mid shore. You could net a brown shrimp, sea hare, green sea slug, and juvenile wrasse if you're lucky.
I'm sure this is waffly but that's how I write
