By Road. Leave the M27 at junction 11 and take the A32 into Gosport town centre. Follow the signs for Gosport town centre, (you will notice signs at Fareham that also say town centre but you should follow the signs to Gosport). Keep going towards Gosport town centre, some of the landmarks will be the Kwik Fit Garage on your left, Crown Bingo on your right and St. Vincent College on the left hand side. Go through a set of traffic lights about half a mile past the college and straight on all the way into Gosport. Gosport Marina is on the left hand side just before the Castle Tavern.
By Rail. Catch a train to Portsmouth Harbour railway station (not Portsmouth & Southsea) – from London these go from Waterloo Station, fast trains take just under 90 minutes. There is also a train from Victoria. From Portsmouth Harbour station follow the signs for the Gosport ferry (not the Isle of Wight ferry). The trip across the harbour takes about three minutes and a return ticket costs £3.30 / £2.20 concessions.
On leaving the ferry, you can walk to the marina in about 3 minutes. Walk up from the ferry to the road and turn right, you will pass the Castle Tavern on your right hand side, the entrance to the marina is 20 metres past the pub.
