Always worth pulling in here to grab a shot of this iconic little bothy with the monstrous mountain resting peacefully behind.
Black Rock Cottage is a small self-catering coastal cottage, so plan like you are staying in a remote holiday rental rather than a hotel: expect narrow single-track roads and limited mobile signal, bring groceries and any special supplies because the nearest shop may be a drive away, and check with your host about heating and whether there is a wood-burning stove and firewood. There is usually off-street parking and a simple kitchen for cooking, but Wi-Fi can be patchy so download directions and entertainment ahead of time; durable shoes and waterproofs will make shoreline walks and wildlife spotting much more enjoyable, and if you have mobility needs ask about steps and access before you travel.
