We went to Brownsea Island yesterday which in between Sandbanks and Poole in Poole Harbour in Dorset. It is owned by the National Trust and jointly managed with the Dorset Wildlife Trust. It is the last remaining refuge for red squirrels in southern England. It is a really special place and well worth a visit.
Check the National Trust Brownsea Island website here to find out when the island is open for visitors – it is rather limited until next spring so check it out carefully before attempting a visit.
