Re the above pic: A tarmac road leaves the A198 on a prominent right hand bend and continues straight towards the woods where the castle sits. This road forks just inside the woods. Take the left hand fork and you'll soon pass a wide track on your left leading to a gate (a good view of Tantallon Castle from there). Don't take this track, though. Keep straight ahead on the tarmac and you'll soon see a faint dirt track heading off left. This will lead 50 metres or so directly to the castle. Hope that makes sense!

Options to get there for our (as it stands currently) merry band of four - Dave, coming up from Newcastle as usual I presume? You could get the train to Dunbar and then have a pretty straightforward ride to Belhaven, through the John Muir Country Park, Tyninghame Woods, and on up via Scoughall to the castle. I appreciate you might want a longer ride in so I'll leave it to you explore potential bike routes to Dunbar.
Phil: Riding from Fife or driving/taking the train over the Forth? Either way, the John Muir Way will take you nearly all the way to North Berwick and it's not far from there. Thinking about it, I'll dig out an Edinburgh to Dunbar mostly off-road route that I've done several times and share the Gpx file with all three of you.
Justin: We could meet up and ride out there together (Phil too if he fancies it). Alternatively, if your time's a bit limited I could drive us part way out there and ride in from, say, Gullane. The same applies to you Phil in fact. Ride with us or I've plenty of room for three bikes in my van, making for a shorter ride in.
Lots of food for thought there and we can pad out the plan as we go along. Any questions just fire away.
