If you want to discover Edinburgh's coast, then this is the tour for you. You'll kick off your tour by cycling right beside Arthur's Seat, Edinburgh's extinct volcano as you ride through Craigmillar Castle Park and into Holyrood Park. Then, it's onto Duddinston Village where you'll pass by Scotland's oldest pub before heading to Portobello Beach. On the ride back, you'll take the Victorian-era Innocent Tunnel which was built in 1860 and runs underneath Holyrood Park.
