Tucked past Two Lovers Point on Guam's northwest coast, Tanguisson Beach sits on the site of an old power plant and is one of the island's classic shallow-water snorkel spots. White sand against deep turquoise water and mushroom-shaped rock outcrops make it a favorite photo stop, and the shallow, reef-sheltered cove (roughly 1-4m deep, 10-15m visibility) lets beginners get close to coral and reef fish without any diving. Some coral here still shows scarring from the 2015 and 2017 bleaching events, and just beyond the reef a Venturi-effect current squeezed between Guam and Rota runs dangerously strong — a swimmer was swept out and required a multi-agency search as recently as February 2026. With no lifeguard on duty, snorkeling is only safe inside the reef line.

Good to know
SafetyNever swim past the outer reef line. A Venturi-effect current squeezed between Guam and Rota accelerates dangerously offshore here, and there's no lifeguard on duty — in February 2026 a swimmer was swept beyond the reef, triggering a multi-agency search. If caught in a current, don't fight it: swim parallel to shore to break free.
SafetyThe entry path and shallow reef bed are studded with sea urchins and sharp volcanic rock/coral fragments — going barefoot risks cuts and punctures. Wear reef shoes, and be extra careful during the rainy season or heavy swell, when the rocky entry gets slippery.
SafetyOn quiet weekdays there may be no one around to help if something goes wrong. Bring anti-fog for your mask and consider a flotation vest, avoid snorkeling alone, and enter/exit only from the marked shallow cove rather than near the exposed point.
RulesThis is officially a shallow snorkel-only area, not a dive site. Check NWS Guam's high-surf and rip-current advisories before you go, and skip the water entirely if a High Surf or Small Craft Advisory is in effect.
MannersDon't stand on or grab the coral and volcanic rock — much of it is already scarred by past bleaching, and even light contact slows recovery. Keep your fins and hands off, and let animals be if you spot any.
RulesTaking pieces of coral, shell, or rock as souvenirs violates Guam's coastal ecosystem protection rules. Use only reef-safe (oxybenzone-free) sunscreen.
SeasonIt's open year-round, but the calmer summer months (roughly May-October) are safer for snorkeling; November-March brings bigger north-facing winter swells (7-10ft+) and frequent High Surf Advisories, raising the risk considerably. Check tide tables before you go — low tide exposes more reef and rock.
Practical info
It's easiest to reach by rental car along the road past Two Lovers Point (about 10 minutes from Tumon), and while parking is free, spaces are limited. No tour booking or dive permit is needed for shore snorkeling here, but double-check current opening hours, parking availability, and any active surf or rip-current advisories through a local source right before you go.
