I have just returned from a trip to Lundy Island. It is safe to say its an awesome place with really good wildlife. We had two sessions with seals and about 2 hours on the island. The visibility in the water was hopeless so viewing seals underwater was hard unless they came within about 2 meters. On land we had just enough time to walk a bit of the coastal path and photograph some species living in the remote cliffs that surround the island.
