Yes. Armenistis is only about 2 km (1.2 miles) away, so the resort village and its harbor are easy to fold into the same stop, giving you two distinct atmospheres in one short visit.
Ikaria's coast road connects Gialiskari to the island's airport, roughly 26 km (16 miles) away, and to the main port at Agios Kirykos, which is farther and takes longer depending on the route. Public buses on the island run on a limited schedule, so a private transfer gets you there directly, on your own timing, without waiting for a connection.
A couple of hours is enough to walk the jetty, see the chapel, and stroll the beach. If you want to swim or linger over a coffee by the water, plan for closer to half a day.
The jetty is a flat, short walk out to the chapel, manageable for most visitors, though it can get sea spray in choppier conditions, so shoes with grip are a good idea. It's a quick, low-effort detour rather than a hike, which is part of why it works well as a brief stop within a longer day.
The sandy beach at Gialiskari itself is shaded by pines with calm, shallow water that suits families. Nearby Messakti beach is more open and a favorite with windsurfers, so it's worth choosing based on whether you want a swim or some wind.
Gialiskari is a small fishing village on Ikaria's north coast, framed by pine trees and known for one striking sight: the whitewashed Chapel of Analipsi, perched at the end of a stone jetty as if floating on the sea. Paired with the turquoise water and sandy shoreline just beside it, it's one of the more photogenic stops on the island.
