This is where most of Guam’s bookable GetYourGuide products are. When we checked the partner feed in October 2026 it held only a dozen listings for the whole island, and six of them start in Piti, about ten minutes’ drive west of Hagåtña and roughly 25 minutes from the Tumon hotels. They fall into two groups: time on the water — a dolphin-watching cruise, guided snorkelling in the Piti Bay marine preserve, a guided beach dive and the underwater observatory — and island-culture experiences built around coconut, food and an evening show.
Be aware that these listings have few reviews so far; several are new to the platform, so read the full description rather than relying on a star rating. Prices are shown as indicative “from” prices in euros and vary with the option you choose. Check in particular whether a hotel transfer is included or whether you need to make your own way to Piti. There are no GetYourGuide walking tours of Hagåtña itself — the town is easy to see independently, and island sightseeing tours that stop at the plaza and Latte Stone Park are sold at hotel tour desks. For shows and the sunset cruise, see Tumon & Tamuning tours.
Our pick of Hagåtña & Central Guam tours & tickets
from €48 Dolphin Watching Cruise & Underwater Observatory
A boat trip along the coast to look for spinner and bottlenose dolphins, with the option of adding a visit to the Fish Eye underwater observatory. Dolphins are wild, so sightings cannot be guaranteed.
from €30 Underwater Observatory & Coconut Experience
A guided visit that explains the role of the coconut tree in island life, then takes you down into the underwater observatory, with time for photos in the garden. A buffet lunch is optional.
from €39 Eco Snorkelling in Piti Bay at Fish Eye Marine Park
A snorkelling tour of the Piti Bay Marine Preserve with a certified guide, swimming among reef fish and corals. A sensible choice if you are new to snorkelling.
from €80 Guided Scuba Dive at Dogleg Reef
An easy-access beach dive for certified divers and first-timers alike, over coral and a sand bottom with tropical fish. Resident green sea turtles are often seen.
from €85 Island Cultural Dinner Show with Buffet
Island and international dishes in an open-air garden beside a lagoon and waterfall, followed by cultural performances with music, hula, warrior chants and a fire-dance finale.
from €39 Island Heritage & Coconut Experience
A guided introduction to island life: taste fresh coconut juice, learn to grate coconut and extract the milk, then take a tropical tea break by a waterfall.
Booking tips
- Confirm the meeting point and transfer. These activities start in Piti, not in Tumon. Some options include hotel pick-up and some do not; a taxi both ways adds noticeably to the cost.
- Go in the morning for the water. The sea is usually calmer and clearer early in the day, and dolphin cruises and snorkelling are the first things to be cancelled when wind or swell picks up.
- Book early in your stay so there is time to rebook after a weather cancellation, and read the cancellation terms before you pay.
- Bring a towel, a rash vest and reef-safe sunscreen. If you plan a first dive, read the medical questionnaire in advance and leave a sensible gap before your flight home.
