General Description

Main coverage of the Scilly Isles HERE 

This used to be the quieter side of Tresco; the ferries from St Marys all land their passengers at New Grimsby and it is there that the souvenir shops and cafes are to be found. Visitors landing by ferry all make a bee line for Tresco Gardens so the area around Old Grimsby tends to be off the beaten track. 

The only draw back is that you’ll have to walk half a mile over the island to the Post Office for your morning news paper.  In SW winds on a sunny day the beach is a delight but regrettably one is no longer allowed to anchor there and dry out.

They have laid out visitors’ moorings but if you have a shallow draft keel you can anchor closer in which gets you out of the main tidal stream but, regrettably, anchoring close in, inside a line from Long Point to Blockhouse Point, is no longer permitted.
