As of last year there was not. I suggested to the Manager that they put one up.
It's easy to find on the trail though. If you are heading to the bridge, as you ride along the canal, right BEFORE you cross the road to get to the canal side of the trail, there's a wide opening that goes up a bit of a steep hill. Well tracked and easy to follow. I'll see if I can mark up a map and post it here.

See if this gives you an idea. This is exactly where you turn off the trail to get to the HI - Express in Houghton. There will be MANY tracks to follow along side the road to get you there. Don't do anything stupid.....take it easy and don't do anything to draw attention to you and your group. This "trail" has been taken to the hotel for several years now.

Click on "earth" or "satellite" view to see the details. The "trail" going up the hill is visible. Follow Calverley and Park Rd's to get to the HI - Express. It's not as far as it may look.
