I know this has now hopefully been covered, but I fancied a good old waffle.
I’ve always joined it from great bear, by crossing the road and riding to the top of Ladies combe(not ladies edge) ride to the lone tree in the grassy clearing and look south for a gap in a earth bank. Go through there and follow the trail to the road again.
You’ll see the five lords Trail marker to you’re right but you’ll be dropping in directly in front of where you should’ve popped out.
As Jambo says, keep left of the gully at the bottom, the trail does go through a wide gap in the bank there, but DO NOT follow that route, keep right of the bank and gully and stick to the single track, you will drop into the ditch for a 50 metre or so section before popping out into more sublime singletrack.
Keep left of the bank at all times, to get out you have 3 options.
1. Heading to the village of Nether Stowey, you’re best to avoid the worse of soggy bottom track by seeking out a rarely used (non)track that only myself and squirrels appear to use.
To find this you’ll need luck, observation and holy proof clothing.
Staying right of the bank the trail climbs, nearing the dense cutting through holy trees, you should just make out an animal track heading off to the right, it’s vague and occasionally off camber, when you get to the holly trees, begin heading down and pick a slalom route directly down the fall line of the hill through, there is a way, but you will feel the holly leaves. At the bottom, find the gate to your left and go through it, then head straight on the Stowey.
2. To return to the old coach road, th one you crossed maybe 5 mins ago, follow the single track the climbs steadily left and back up the ‘Walford’s Gibbet’. Left on the road and that’ll take you to the north end of the great bear, etc.
3. Retrace your steps.
