Take M74 until it Joins M8 and head for Glasgow Airport. Keep on M8 until jcn 30 for Erskine bridge. Cross over the Erskine Bridge and take the A82 first left off the bridge (signposted to Crianlarich) as far as Balloch. (bottom of Loch Lomond about 30 minutes from Rowardennan.)
When you get to the Stoneymolan roundabout at the beginning of Balloch take the last exit, A811 signposted to Stirling follow the road for about 10 miles until you come to Drymen. Turn left to Drymen, pass the Buchannan Arms Hotel on the right and when you see ‘The Hawthorns’ bed and breakfast turn left. (Road signposted to Balmaha). Rowardennan is about 10 miles from here. The road gradually get narrower as you get nearer to the loch.
After you have driven through Balmaha there is a very steep hill on the bend carry on along the narrow road and you will pass Millarochy Bay car park on the left and then the camping and caravan club site. Pass this site and Cashel Campsite about one mile from here on the left. Carry on for about 4 miles until the road ends at Rowardennan Hotel.
The entrance to the log cabins is just before the hotel car park but there is a security barrier so on arrival drive your car into the hotel car park and open the gate into the grounds. Number 19 is left through the security barrier then on the right hand side as you cross over the bridge at the river.
