A walk on St David's Day, even if there was hail. Nice flattish walk ending with lovely sea views. Got a little lost in the estate coming back, and stopped recording at a point where I'll be retracing footsteps.

At low tide, the water escapes quite far.

Parc Slip is a nature reserve run by the Wildlife Trust of South and West Wales, set on the site of an old coal mine. Disaster struck in 1892, when an explosion down in the pit killed 112 men and boys as well as 16 ponies. Today you can see a memorial made of stones as a tribute to the lives lost in this tragic incident. There's a great shared path through the reserve, where you can see many different species of birds, mammals and invertebrates across the wildflower meadows and wetlands. Keep an eye out for the wooden badger too!
