Birdoswald is well-signposted on the A69 travelling from both the east and west. The English Heritage car park immediately east of Birdoswald fort is primarily designed for visitors to that monument. That much is clear from the fact that you can get the cost of your parking (£4 in 2015) reimbursed when you visit the fort. However, you can also use it for exploring the surrounding bits of Hadrian’s Wall.
Do not park in and obstruct the bus turning area (you should hear what coach drivers call the idiots who do this!) and do not leave valuables in your car. There are posters warning about thieves for a good reason (last time I was there some cars were broken into only a couple of days later). Follow signs for the Hadrian’s Wall Path to access sites to either side of Birdoswald. Stout footwear is advisable.
