Petroglyph Beach holds the highest concentration of ancient rock carvings in Southeast Alaska, with around fifty petroglyphs scattered across the tidal zone north of town, a short walk from the ferry terminal along Evergreen Avenue. The carvings — faces, spirals, killer whales, and abstract forms — appear at their clearest at low tide, when the wet rock makes the incised lines more visible. You can visit independently at any time; there is no fence or fee.
The Alaska State Parks information board at the site provides context and asks visitors not to make rubbings directly on the originals. Concrete replicas have been installed nearby precisely for this purpose, and making rubbings of those is actively encouraged. The best light is in the morning on overcast days, which are common in Wrangell — the soft grey light picks out the carved lines without glare. Allow an hour for a careful look at the main concentration of carvings.
