If you're in England and planning to visit Bristol you can get there by train, bus, or plane. (Or, of course, drive if you have a car).  Bristol has its own international airport (BRS) which is situated about eight miles south of the city. It mainly takes flights from within the UK and Europe, but now does some charter flights from the U.S. and has a link to Newark/New York. New routes in 2011 include Aer Arann and Air Lingus operating flights via Dublin to the States, and Blue Island operating twice a day between Jersey and Bristol. 

If you're already in England the simplest way is probably the train, as the distances are not really so great as to require a flight if you are coming from, say, London. (There are two regular train links from London Paddington, one to Bristol Temple Meads in the city centre and the other to the Bristol Parkway on the northern outskirts). 

Coaches (National Express and Megabus.com) also operate between Bristol and many UK cities, although these, of course, take somewhat longer. It will take you 2,5 hours to get from London Victoria Coach Station to Bristol.

Car access is via the M4 from the East and West (if coming from the east, turn off at junction 19 onto the M32) and the M5 from the South-West and North. If approaching from the north down the M5 with the intention of coming off at Junction 16 (A38), be very careful as this junction is YARDS away from Junction 15 and you will be crossing paths with traffic joining the M5 from the M4 - it would be safer to leave at Junction 14 (to Thornbury) and come down the A38 from there. Motorways do get congested at busy times, so bear this in mind, especially early morning and later afternoon when the commuter traffic brings gridlock to the area.
