The cycle track veers off the old line outside Ravenscar.
One guide suggested we'd be able cycle through the disused tunnel, but it looks like it's been a long time since anyone pedalled through this tunnel!
The tunnel isn't easily accessible, but that wasn't going to stop us taking a look, so we battled past vicious clumps of stingy nettles to get to the entrance which, conveniently, had an open door.
With an invite like that how could we resist popping in and taking a peek?
Not surprisingly, it was absolutely pitch black inside the tunnel, and being rubbish urban explorers, we'd forgotten to bring along a torch.
I was keen to wander through the entire tunnel, so I kept taking photos to see what was looming up ahead.
Apart from a small stream running though the centre, the tunnel was dry and in good repair - a testament to its builders.
The far end of the tunnel.
Walking back out of the tunnel into the sunlight.
We had planned to go on Scarborough but a mixture of the searing heat, a late start and the fact that we wanted to watch the England World Cup game meant that we changed our plans.
Instead we decided to head back into the delightful Robins Hood's Bay, grab a beer and an ice cream and watch England struggle to a 1-0 victory over Slovenia.
Looking out to sea.
Hurtling along a downhill stretch back to Hawskker, pass Fyling Hall (sorry about the wind noise).
We're on National Cycle Route #1!
'Boggles' are the local name for hobgoblins who were thought to live in caves along the coast.
Boggle Hole is famed as a place where local smugglers used to land their contraband.
Back to Trailways to drop off our bikes.
A look back at the station.
We walked back towards Whitby along the old line.
View of the River Esk taken from the thirteen arch Larpool Viaduct, built by John Waddell.
Construction of the impressive
brick structure began in 1882 and carried the Scarborough & Whitby Railway over the River Esk.
It's a long and high viaduct at 279 m (915 ft) long and 36 m (120 ft).
The only remaining line into Whitby.
After walking across the viaduct, we left the old line and headed into Whitby for beer.
