This route is so much fun - and is part of what is probably the best grade 1 scramble in Snowdonia.

The south ridge is the easier way to reach the top of Tryfan, but it still has it's moments near the top.

You can't miss these two huge stones right on the summit of Tryfan. Traditionally climbers would jump from one to the other to gain the freedom of the mountain. But be warned people have died in the attempt.

Fine on a gravel bike, but there are styles along the way which can be a bit tricky if you're riding a loaded bike. Worth the effort through - stunning views.

Well worth waiting for a misty day, the light here across the lake was amazing, a real treat. There is also a bench so you can sit and watch the world go by
