After a relatively quick bus journey, we arrive at Calshot Beach car park and we immediately head straight off toward the beach huts where we finished the walk yesterday, for the start of today's walk. Calshot Spit is a one mile long bank of sand and shingle created by coastal deposition, which means the materials of sand or shingle are moved down a headland by the waves (longshore drift) and eventually build up and start to project out to sea after meeting a flowing river. The spit here was boosted in 1703 when the great storm of that year washed a large amount of shingle onto it making it more the substantial structure we see today.
