"Part of the spectacular wind- and ocean-eroded shoreline of the Te Whanganui-A-Hei Marine Reserve, Cathedral Cove, on New Zealand's Coromandel Peninsula, is reached via an undulating coastal track that takes around 40 minutes to hike. To avoid the inevitable crowds, it's best to visit the massive stone arch early in the morning or late in the afternoon, and the natural shower of the arch's waterfall is a refreshing option after the walk. The stunning beach is also popular for swimming, and en route there's good snorkeling at Gemstone Bay and Stingray Bay. To arrive at the cove by sea (a short hop from the nearby resort town of Hahei), contact Cathedral Cove Water Taxi."
