Shortly after the bridge there is another junction in the path anachronistically named Picadilly. The right turn here leads up to the Lairig Ghru, the most famous mountain pass in Scotland. This pass takes you from Speyside to Braemar, a distance of over twenty miles. It rises to 835m. Walter Poucher writing in 1947 said that a bicycle was a disadvantage, and this is still true despite improvements in bicycle technology.
Blizzards can occur there even in summer.
Continuing to Loch Morlich though there's another locked gate, a more serious one this time with a deer fence. If you haven't got the key, getting over the stile is possible, but it helps if there is more than one of you. Turn left at a forest road leading to Rothiemurchus Lodge. A mile after this you reach Loch Morlich. There is a shop and tea room by the camp site at Glenmore village.
