Obyan Beach (local name Unai Obyan) sits at Saipan's southern tip, right below the international airport's runway, and is famous for offering some of the island's best shore-entry reef snorkeling. The shallow in-reef lagoon is calm and easy for beginners and kids, while a short swim out leads to a dramatic drop-off where white-tip reef sharks, eagle rays, sea turtles, a resident garden-eel colony and abundant hard and soft coral can be spotted. Visibility stays excellent year-round, typically 50-70 ft (about 15-21 m), unless a typhoon warning is in effect, and water temperatures run a warm 28-30Β°C. As of July 2026 it remains one of Saipan's top snorkel spots, largely unchanged in access and marine life.

Good to know
SafetyDo not swim past the drop-off β the return can be difficult against rip currents, and there's a documented risk of getting swept toward open water. Stay on the reef-side of the guide rope and use it to navigate.
SafetyThe beach is long with several entry points, so avoid snorkeling alone; bring a buddy and a visible float/snorkel flag. Watch for mask fog and mild panic if surf picks up.
SafetyCoral, sea urchins and fire coral can cause cuts or stings on contact. Sharks, rays and turtles here are generally docile, but never touch or chase them.
MannersNever stand or step on coral. Keep a respectful distance from turtles and rays and do not feed any marine life.
RulesTaking coral, shells or marine life is prohibited; use reef-safe (mineral-based) sunscreen. Do not disturb the latte-stone ruins next to the beach.
SeasonSnorkeling is possible year-round, but access is closed or unsafe during typhoon warnings; entry is easiest at high tide. The rough coral-and-dirt access road can deteriorate further during the wetter months (roughly June-November).
Practical info
It's about a 10-minute drive from Saipan International Airport, reached via a rough dirt/coral road near Isley Field to a shore-entry point β no boat or tour is required, though guided snorkel trips are also available. There are no restaurants nearby and only limited restrooms, so bring your own water and food; check current road conditions and any typhoon advisories before you go.
