6 Days in Guam: The First-Timer Plan

Heads up: some links here are affiliate links. Book or buy through them and we may earn a small commission at no extra cost to you. We only point you to things we would actually use.

Guam’s real sight list, the beaches, the free War in the Pacific NHP, Hagåtña and the southern loop, fills 3 to 4 days. Six days only earns its keep with genuinely different activities, which is why this plan carries the 5-day itinerary forward and adds a water-sports day rather than a second beach day dressed up as new. Shorter versions run in the 2-day , 3-day and 4-day plans; the 7-day itinerary adds an island side trip on top of this.

Day 1: Tumon Bay, arrival and the beach

File the free Guam Electronic Declaration Form at cqa.guam.gov , up to 72 hours ahead; every traveler needs one, US citizens included, electronic-only since February 2025. Bring a REAL ID-compliant photo ID; Guam is a US territory so no passport is needed, but REAL ID enforcement for flights has been in effect since May 2025.

Collect your rental car at Antonio B. Won Pat International Airport (GUM). Public buses skip Sundays and run limited hours otherwise, and the Tumon trolley never leaves Tumon. Settle into Tumon Bay itself, a two-mile crescent of reef-protected water inside the Tumon Bay Marine Preserve. Ypao Beach Park at the bay’s south end has picnic pavilions and BBQ pits. Wear water shoes on the reef flat, and close the night on Pale San Vitores Road, Tumon’s restaurant strip.

Day 2: Two Lovers Point, Hagåtña and the free War in the Pacific NHP

Start at Two Lovers Point (Puntan Dos Amantes), $3 per person, open 10 AM to 7 PM, a clifftop lookout roughly 378 feet above Tumon Bay tied to the Chamorro legend of two lovers who leapt rather than be separated. Drive to Hagåtña, 15 to 20 minutes away, for the free Plaza de España, the Dulce Nombre de Maria Cathedral-Basilica (founded 1669, confirm current hours), Latte Stone Park’s eight ancient latte stones, and the Guam Museum ($3 adult, closed Mondays).

Finish at War in the Pacific National Historical Park , free at every unit, the only NPS unit dedicated to the Pacific Theater of WWII. The Asan Beach Unit covers the actual 1944 invasion beach; the Agat Unit shows visible Japanese fortifications. Guam has no UNESCO World Heritage Site, so this free park is the trip’s real historical anchor.

Day 3: The full southern Highway 4 loop

Roughly 3 hours of driving alone, so start mid-morning. Umatac, 45 to 60 minutes south, has the free Fort Nuestra Señora de la Soledad and a monument popularly tied to Magellan’s 1521 landing, though Legazpi’s 1565 claiming voyage is the better-documented event here. The free Taleyfac Spanish Bridge is a quick nearby stop. Continue through Merizo to Inarajan’s Natural Pools, tide-protected and safer than most open beaches, and finish at Talofofo Falls Resort Park ($20 general, $12 military), where the included cable car and the Yokoi’s Cave replica cover the story of Sergeant Shoichi Yokoi’s 28-year jungle holdout, found in 1972.

Day 4: Ritidian Point and Gun Beach

Ritidian Point is the island’s most pristine beach, but open Wednesday through Sunday only, 7:30 AM to 4 PM, closed Monday, Tuesday and federal holidays, plus weather closures. Confirm your day four falls on an open day. The drive is 30 to 45 minutes, unpaved at the end. On the way back, stop at Gun Beach, free, 10 minutes from the Tumon strip, with shore-accessible reef snorkeling ranked among Guam’s best and WWII-era gun emplacement remnants on the point.

Day 5: Cocos Island

Cocos Island, a small day-resort island off Merizo, is a 12-minute ferry crossing, roughly $40 adult and $20 child round trip. The day resort has a pool, snorkeling, kayaking and parasailing (around $100 for two adults). Dry season (December to April) gives the calmest water and best visibility. Book through the day-resort operator at Merizo Pier and go early.

Day 6: Fish Eye Marine Park or a Blue Hole dive

Two honest options for day six, pick based on whether you dive. Non-divers should head to Fish Eye Marine Park at Piti, a pier-mounted underwater observatory (roughly $10 admission) over the Piti Bomb Holes Marine Preserve, a reef pocked with WWII bomb craters now thriving with fish and coral, no wetsuit required, just a walk down a spiral stair to viewing windows. Add the snorkel-off-the-ramp option if the tide and weather cooperate.

Certified divers should book Blue Hole instead, Guam’s signature advanced dive site off Orote Point at the mouth of Apra Harbor, a limestone shaft dropping from about 50 feet to over 130 feet with visibility often past 100 feet, turtles, reef sharks and barracuda schools included. This is genuinely an advanced dive, not a beginner add-on, so book it only if your certification and experience match.

Do you need to dive to enjoy Guam’s water?

No. Fish Eye Marine Park and Gun Beach both put Guam’s reef life within reach of anyone who can wear a mask and fins, no certification required. Diving at Blue Hole is a real option for certified divers wanting Guam’s best underwater site, but skipping it entirely still leaves a full six days of genuine sightseeing.

Guam’s typhoon season runs July through November, sharpest risk August through October; December through June is dry, February the most-cited best month. Watch weather.gov advisories if traveling in the wet half of the year. One concrete tip: book the Blue Hole charter or the Fish Eye combo the same week as your Cocos Island ferry, all three depend on calm-water windows that fill up together in peak season.
