When driving to Islay most people probably take the A82/A83 route from Glasgow. If you have a bit of spare time and the weather is nice I now recommend to take a detour via the A817 Haul Road (and A814) between Loch Lomond and Gare Loch / Loch Long. The views are fantastic, especially on the western part of the A817. The Arrochar Alps and other mountains line the horizon, a great view.
I had known about this route for many years, but for various reasons (in particular weather and time) had never got around to drive it. In June 2018 I had both the time as well as some decent weather, so I decided to go for it. Well worth it.
A popular stop on the journey to Islay is the Rest and be Thankful at the top of the mountain pass between Loch Lomond and Loch Long. This is the view into Glen Croe on the Loch Lomond side of the area. You can make out the A83 coming up on the left. Below the old drovers road, which is now used as an alternative route when a landslide has closed the A83. Taken on a journey to Islay in April, still some snow on the top of the hills.
A follow up to the view of Islay and Jura from Goatfell, here a closer look of the Paps of Jura. Not the greatest quality, but this was back in 2004 when digital cameras weren’t as advanced as they are today.
