When Is the Best Time
The best time is usually from mid-April to September. However, Canisp can be walked all year during good weather conditions. It is hard to walk in wet weather but not impossible to walk the trail in poor conditions (I did it after one very wet day), but it is better to wait for dry days.
For detailed weather and crowds information check out my article from Stac Pollaidh one of the Assynt Hills.
Best Months to Visit
Location and Tips
Canisp is one of the spectacular Assynt hills. The easiest way to the top is from the lay-by of the road A837 past the Ledmore junction. There is a visible path from the car park which leads over the bridge to the moorland. Be careful because this part is very boggy, and a stream cuts the path. I did this hike after heavy rainfall the day before. Nevertheless, if you have good walking boots and a good mood, it is not a big deal;)
After few miles, the path ends. Go up through the stony ground, and you can't get lost. When the stony ground ends, there is a visible path again, and the views start to be stunning, with Assynt hills on the left-hand side. The top can be easily reached in 3 hours. From the top, you can see Suilven, Cul Mor, Stac Pollaidh and Quinag. Canisp is a fine place with excellent views. Canisp is 847 meters high and is one of the Corbetts.
