Ballyheirnan Bay is a popular surf spot located on the Fanad Peninsula in North Donegal. It features a curving beach with north-facing sandbars that attract surfers from the Letterkenny area. The bay is known to be one of the busier beaches in the region, particularly during the summer months when surf schools operate and beginner surfers come to learn.

The surf at Ballyheirnan Bay works best with a northwest to north swell. It can handle swells starting from around 2ft (0.6m) and breaks over sand, making it more forgiving for those still getting the hang of things. The waves are primarily beach break types and come in both left and right directions. For the best sessions, aim for low to mid tide, and if possible, catch it when the wind is coming from the south. This spot is suitable for beginners who are looking to get some practice in a less intimidating environment.

Ballyheirnan Bay has its share of enjoyable days but can be a bit hit or miss, depending on the conditions. It is a great place for those new to surfing, thanks to the manageable waves and supportive vibe among the local surf community. Just keep an eye on the forecast for the best chances of a good session.
