If approaching from the Solent, the entrance is identifiable from the high cliffs of Anvil Point. When nearer, the rocks of Old Harry (Handfast Point) are clearly visible. The Swash Channel is clearly marked.

When leaving for, or approaching from west, beware of the race at Handfast Point on the ebb tide. The Harbour is accessible at all states of the tide and is only dangerous in very strong S and SE winds, particularly on the ebb tide. The entrance channel ‘The Swash’ passes between the Training Bank on the western side and Hook Sands to the east. Be careful of the Chain Ferry, just at the entrance, as the ebb can run 3 to 4 knots.
