Swimming to the R as you face little lameshur bay, swimming around the first point is Europa Bay. Or, park at the Lameshur ruins parking lot and take the Lameshur trail up. The second trail to the left is the Europa bay spur trail. The trail looks much harder that the swim. It truly was a once in a lifetime experience. The fact the there were 2 swimming and not hiding in a crevass,the fact that they noticed me and were circling me very closely, and the fact that we managed to get pictures of any of it.
The "still looking" photo is absolutely amazing. Seriously consider entering in a contest. It must have made your day to see them swimming about so freely!
