If it's the Newcastle Gateshead Tuplip it's actually on the Team Valley in Gateshead on the big Industrial Estate. Traffic is very busy at rush hour but it's only across the river from Newcastle. There buses from the Team Valley straight to Newcastle or to Gateshead Metro station which is one stop from Central Station, if the traffic's good you could drive into Newcastle in 10 minutes. There's a car park near the City Hall and an underground one beneath the Gate don't know the charges tho.
Places to go, well the great St James Park of course! The Gate which has a lot of different bars and a cinema (
www.thegate.com/co.uk?), the Bigg Market, dead busy and a bit charva-ish. The Laing museum, free, The Discovery science museum, free, The Center For Life about 7 quid but worth a vist and a Military Museum in Exhibition Park, about 1.50. There's Eldon square and Northumberland Street for shopping, a comedy club on Westgate Road and places to eat and drink on Dean Street and continuing on down to the quayside. Go into one of the Nexus travel shops in Gateshead, Central Station or Monument metro stations and pick up a Great Days Out brochure, it tells you about Newcatle stuff and days out based around the metro system, VERY handy. Enjoy yasels!
