We made the hike down to Isaac Bay and really enjoyed the outing. Going on a sunny day makes the colors of the water, hills, and sky blindingly surreal. Simply a beautiful spot and pretty quiet- there were maybe three or four other cars in the lot (plenty of broken glass though, sad to say) and a handful of folks down on the beach.
The hike itself was not bad, the incline fairly gentle and not as thorny as we expected, though very overgrown in sections. My hiking partner wore shorts and sneakers and came out with a few little scratches. It took us about 20 minutes to get from the parking area to the beach steps.
We are glad we didn't bother to bring our beach gear down with us, as the water seemed a bit too rough for us to swim on the day of our visit (perhaps we were spoiled by our day at Shoy's!) Sunglasses, hat, and plenty of water are recommended, even though it's a pretty short round trip hike, the sun is incredibly intense and there's no shade on the trail! Enjoy and happy hiking.
