nearest station to the ground is actually Pokesdown, which is around a twenty
minute walk from the ground. Bournemouth station is half as far again.
If you're driving down then there's a big car park at the ground. This will cost you 50p an hour though, and you'll probably wait an age to get out after the game. Much better, particularly if you arrive reasonably early, is just to part in the streets off Holdernhurst Road.
The two pubs nearest to the ground, the Queens Park and the Talbot, are both home fans only. If you arrive by train then there's the Bell right outside Pokesdown station, but it's nothing special. It's normally recommended that away fans go to Wetherspoons' Sir Percy Florence Shelley (no colours though!), Mello Mello Bar, or Shark Bites, all of which are in Boscombe and around a 15 minute walk from the ground. My recommendation though, particularly if you're driving down or arriving at Bournemouth station, is the Firkin Shed. Be warned though that it doesn't normally open until 12.00. You should also be aware that they discourage people using phones for social networking. Either go outside with the smokers or face a fine of a pound (which goes to a local charity)! Another option in the same area is the Cricketers.
Not far from Bournemouth station, although the opposite direction to the ground, is the Christopher Creeke, which is another Wetherspoons outlet. Just down the road is Inferno, which incorporates a micro brewery.
