I live there now and it's great. If you return try the guided walk to Seymour Tower. I did a short blog post back in 2012 with photos, including the rescue tower halfway out. https://www.tombrossman.com/blog/2012/seymour-tower-walk/

TL;DR 30-40 foot tidal range. Sea level rises faster then walking speed at times, you really must pay close attention.
