So many people visiting Cornwall miss out on the Scilly Islands. A great pity - but so much the better for the rest of us!
A great sea trip is on the RMS Scillonian III which sails from Penzance harbour to the island of St Mary's in the Islands. She sails 6 days a week (except Sundays) and returns the next day, except at Easter and in August when day trips are available (see the schedule for 2007 on http://www.islesofscilly-travel.co.uk/daysc3.htm)
There is a commentary on the places the boat passes.
Full information and tarifs on the Isles of Scilly Travel website, they are a bit complicated to give here.
But don't miss going to Scilly!
You can get to Penzance on the A30 or A38 motorways, in your own vehicle or on a coach. There are coach services at the station downtown. The train also terminates at Penzance station, right beside the bus station. Helicopters and ferries are available for transport to and from places like the Isles of Scilly. Once you're here just use your feet - the town isn't that big and it's fun to stroll around and find things you didn't know existed. To get out of the town and to outlying towns and villages there are plenty of regular bus routes.
Penzance has a small bus stand opposite the railway station and all the buses start from here to the different places near and around Penzance. The best option though is to walk (as I used to) all over Penzance except when going out of town or when carrying luggage!!! The frequency of the buses is quite less so be prepared to be late if you are in a hurry to get somewhere!!! Or walk!!! It's faster than waiting for the bus!!!
Penzance train station is located at the bottom end of the town. A typical high ceilinged Victorian building. It is an end of the line station; probably why the locals refer to anything East of the region as "up the line".
The staff are always helpful although there aren't many of them. If you have a few enquiries or a lot of tickets to buy it is a good idea to arrive early, There can be huge queues in the summer and if you don't buy on the platform you will lose any discounts (eg; student or family) that you are entitled to.
very small end-of-the rail station of Great Western, I found it friendly and efficient; even if the hours of operation are tied directly to operating hours. The staff is friendly and the station decor is artistic. The bus station is essentially attached on the outside with a tourist information center. Panoramic views of the coast are just a stone's toss away with great views of St. Michael's Mount. The station is just next to the harbour and on the mere edge of the city center. This railway stations serves the town of Penzance and is the western terminus of the 305+ mile long Cornish Main Line from London-Paddington Station which takes roughly 5 hours journey. Visitors are welcomed to Penzance on a stone bearing two languages - English and Cornish. Rating: 4 stars out of 5.
