Getting there & around
From KOA to your Big Island stay
Rent a car at KOA
Compare rental companies at Ellison Onizuka Kona International Airport side by side. Many of them offer infant and child car seats as an add-on: use the Car seat filter and add one when you book.
Opens Booking.com with sample dates about a month out (or the stay dates saved on your trip board). Change them to your trip there. Tots & Trips may earn a commission.

Age-group lens
This plan is tuned for tween travelers, so keep the highest-energy activity early and preserve a low-stakes fallback.

Day by day
Day-by-Day Plan
5 days, each paced morning to evening. Gold tags mark the nap and rest windows the plan builds in.
Day 1: Arrival and Settle In
Morning
Land in Kona, check in, grab gear. Tweens should help navigate using Google Maps from the airport — give them a real job immediately to signal that this is their trip too. Snorkel Bob's in Kona for gear rental; let the tween pick their mask.
Afternoon
Hapuna Beach for an introductory Pacific Ocean session. Tweens can bodyboard in the shore break (boards available for rent), explore the rocky tide pool edges, and claim their spot. Less structured than younger-kid beach time.
Evening
Kona town walk. Find shave ice (Scandinavian Shave Ice is popular), browse the waterfront shops, and let tweens have $10 each to spend however they want. Dinner at a local spot — let them order themselves.
Tip: Tweens who feel ownership of the trip behave better throughout. Give them agency on small decisions daily (where to eat lunch, what snack to buy, which trail to take).
Est. cost: $70–$120 (snorkel rental, shave ice, dinner, pocket money)Find Day 1 ticketsDay 2: First Full Day
Morning
Hawaii Volcanoes National Park — full immersion. Download the NPS app and let the tween navigate inside the park. Walk the full Kilauea Iki Trail (4 miles, 400-foot descent onto a hardened lava lake floor) — this is a real hike across what was once a lake of molten lava. Dramatic and memorable.
Afternoon
Thurston Lava Tube, Chain of Craters Road, Holei Sea Arch. Let tweens photograph everything. If the park has active surface lava, ask rangers about the closest safe viewing distance. Picnic lunch at an overlook.
Evening
If active lava is visible after dark, this is the night to see it. Otherwise, return to Kona and research the night's sky conditions for tomorrow.
Tip: The Kilauea Iki Trail requires sturdy closed-toe shoes — sandals are unsafe on raw lava. Bring 2 liters of water per person minimum; there are no water refill stations on trail.
Est. cost: $80–$150 (park entry, gas, meals)Find Day 2 ticketsDay 3: Signature Activity Day
Morning
Mauna Kea Summit drive — the 13,796-foot summit is accessible by paved road (the last 8 miles require 4WD but tours handle this). Book through Mauna Kea Summit Adventures or a similar operator. Tweens are old enough to understand the astronomy: 13 world-class observatories sit here because it's above 40% of Earth's atmosphere. The view at sunset is extraordinary.
Afternoon
The visitor center at 9,200 feet is a good mid-altitude stop with exhibits and a bathroom break. Acclimatize here before going higher. The summit at golden hour is stunning photography territory.
Evening
Mauna Kea stargazing is the finest on Earth. After twilight, visitor center staff give an informal laser-guided sky talk (weather and staffing permitting); the public telescope program ended in 2019, so bring binoculars. This is often the highlight of the entire trip for tween-age kids.
Tip: Altitude sickness is real at 14,000 feet — watch for headache, nausea, or dizziness in tweens. Anyone with asthma should consult a doctor. No one under 13 is allowed at the summit by most tour operators; verify age requirements when booking.
Est. cost: $100–$200 (summit tour or 4WD rental, meals)Find Day 3 ticketsDay 4: Flexible Family Day
Morning
Manta Ray Night Snorkel (evening activity — use the morning for Kealakekua Bay snorkeling). Book a morning boat tour to Kealakekua Bay Marine Reserve, where Captain Cook was killed in 1779 — the historical context makes tweens genuinely curious. The snorkeling (100+ fish species, healthy coral) is world-class.
Afternoon
Nap / rest built inReturn, lunch, short break. Tweens can rest or explore the resort independently (within agreed boundaries). This earned downtime matters at this age.
Evening
Manta Ray Night Snorkel departing from Kailua-Kona. The experience of giant rays (up to 16-foot wingspan) gliding inches from your face in dark water, lit from below, is genuinely life-changing. Tweens talk about this for years.
Tip: Do both the daytime Kealakekua snorkel and the manta ray night snorkel if budget allows — they're completely different experiences. Wear a wetsuit on the night tour; open ocean water is cooler after dark.
Est. cost: $200–$300 (two boat tours)Find Day 4 ticketsDay 5: Final Morning and Departure
Morning
Green Sand Beach (Papakolea) — take the local truck ride from the trailhead ($10–$15 per person) for most of the journey, then walk the final quarter mile. The green olivine sand is geologically unique and the hike to the cliff overlook gives tweens a real sense of accomplishment. Waves here are rough — swimming is not safe for most visitors.
Afternoon
Punalu'u Black Sand Beach on the way out. Turtles, black sand, final swim. Let tweens take their own photos and pick their own souvenir. Drive to airport.
Evening
Fly home. Tweens can use the flight to edit and post their trip photos (if you allow it) or write a journal entry about the most unexpected moment.
Tip: Papakolea Green Sand Beach has no facilities — bring water, snacks, and reef-safe sunscreen. The path is exposed and hot. The $10 truck ride each way is absolutely worth it with tweens.

Safety Notes
Altitude sickness is a real risk at Mauna Kea's 13,796-foot summit — acclimatize at the 9,200-foot visitor center for 30+ minutes before ascending, watch tweens for headaches or nausea, and descend immediately if symptoms appear. Volcanic gases at Volcanoes National Park can irritate lungs; avoid high-vog areas and check forecasts before the park visit. Ocean conditions on the Big Island change rapidly — always check surf reports before bodyboarding at Hapuna and never swim at unguarded beaches during high surf advisories. Green Sand Beach's waves are rough and swimming is dangerous; go for the geology, not the swim. Never stand on lava ledges near the coast — they can collapse without warning.
Full Destination Guide
The Big Island gives families active lava fields, manta ray night snorkels, green and black sand beaches, and a landscape that changes from tropical rainforest to alpine desert within 45 minutes—all without a passport or jet lag. It's one of the most geologically dramatic and genuinely accessible family destinations in America.
