Hawaii Outdoor Guide: Campgrounds, Trails, Beaches & RV Spots
Key Takeaways
- Hawaii camping is tent-and-permit based, with essentially no traditional RV infrastructure — plan for a campervan-and-beach trip, not an RV-park trip
- Diamond Head requires advance online reservations for all non-residents, up to 30 days ahead — don’t show up without one
- Waikiki and Ko Olina are the calmest, most toddler-friendly beaches in the islands, thanks to reef protection and man-made lagoons
- Several popular beaches (Sandy Beach, Big Beach on Maui, winter North Shore on Kauai) are genuinely dangerous for young swimmers — treat them as scenery stops, not swim spots
Beaches Are the Real Destination Here
Hawaii’s outdoor identity runs through its beaches more than any other state in this guide — campgrounds are secondary, and the real planning work is matching the right beach to your kids’ swimming ability.
Campgrounds
Malaekahana State Recreation Area — windward Oahu (between Laie and Kahuku)
A long, wide beach shaded by ironwood trees, with Goat Island just offshore — one of the best family camping spots on Oahu. Requires a state permit through the DLNR portal; book as early as your window allows.

Ahupuaʻa ʻO Kahana State Park — windward Oahu
A “living park” where native families still live on the land, with hiking trails, archaeological sites, and beach campsites — a genuinely unique cultural and outdoor experience combined.
Learn more
Waiʻanapanapa State Park — Hana, Maui
A legendary black-sand beach with blowholes and lava-tube caves, plus cabins and campsites. Permits are highly competitive — book the moment your window opens.

Kīpahulu Campground — Haleakalā National Park (Maui)
Grassy oceanfront sites near the Pipiwai Trail, reservable through the national park system — a local favorite worth booking early.

Nāmakanipaio — Hawaiʻi Volcanoes National Park (Big Island)
A concessionaire-run campground with cabins, serving as a good base for volcano exploration.
Learn moreState park fees run $20/night for residents and $30/night for non-residents at standard sites, with a 5-night maximum. Popular sites fill within minutes of the booking window opening.
Hiking Trails
Diamond Head Summit Trail — Honolulu, Oahu
Hawaii’s most popular hike — a moderately challenging climb through historic tunnels and stairways to panoramic Waikiki views. Advance online reservations are mandatory for all non-residents, up to 30 days ahead. Exposed with almost no shade — start early.
Learn more
Manoa Falls Trail — Oahu
An easy, shaded rainforest walk to a 150-foot waterfall. No swimming at the pool, but a genuinely lovely walk — often muddy, so plan footwear accordingly.
Learn more
Pipiwai Trail — Haleakalā National Park (Kīpahulu District, near Hana, Maui)
A roughly 4-mile round trip through a banyan tree and bamboo forest to the 400-foot Waimoku Falls — consistently named a top Maui family hike. Wear closed-toe shoes; the trail gets muddy and rooty.
Learn more
Kīlauea Iki Trail — Hawaiʻi Volcanoes National Park (Big Island)
A roughly 3.3-4 mile moderate loop descending through rainforest onto a solidified 1959 lava-lake crater floor — one of the best family hikes in the park. Note that Kīlauea has been erupting episodically since late 2024; check nps.gov/havo before your visit for current closures.
Learn more
Canyon Trail to Waipoʻo Falls — Waimea Canyon / Kōkeʻe State Park (Kauai)
A roughly 3.2-mile moderate hike to an 800-foot waterfall with real canyon overlooks. No permit required, though it gets muddy after rain.

Waikiki Beach — Honolulu, Oahu
Shallow, reef-protected water where toddlers can wade safely — the reason Oahu wins for young families. Full facilities nearby, plus the Honolulu Zoo and Waikiki Aquarium.
Learn more
Ko Olina Lagoons — west Oahu
The calmest, most predictable water on the island, with four man-made lagoons genuinely ideal for little swimmers.
Learn more
Poipu Beach Park — south shore, Kauai
Consistently calm surf with a lifeguard — a family haven and the most complete visitor setup on the island.
Learn more
Kamaole Beach Parks I, II, III — Kihei, Maui
Lifeguarded, easy-access family beaches, good default options across Maui’s south shore.
Learn more
ʻAnaehoʻomalu Beach (A-Bay) — Kohala Coast, Big Island
Turquoise water and calm swimming, with plenty of room for kids to play for hours.
Learn moreSafety note: avoid Sandy Beach and Makapuʻu (Oahu), Big Beach/Makena (Maui), Punaluʻu and Papakolea (Big Island), and Lumahai/Polihale and winter North Shore beaches (Kauai) as swim spots for young kids — these are scenery and surf-watching beaches with real shorebreak and current hazards.
RV Spots
Hawaii has essentially no traditional RV-park infrastructure. Campervans are the practical equivalent, and even those are limited — most public campgrounds are tent-only. On Oahu, private campgrounds and farm stays are the most campervan-friendly options available. If your family wants a road-trip-with-lodging feel, plan around a campervan rental and private sites rather than expecting full-hookup RV parks anywhere in the islands.
Planning Your Trip
Oahu is the easiest island for a first-time family trip, thanks to Waikiki and Ko Olina’s genuinely calm, toddler-safe water. If hiking is a bigger priority, Maui’s Pipiwai Trail and the Big Island’s Kīlauea Iki both deliver real payoff for a manageable family hike. Whatever island you choose, book Diamond Head and any camping permits well ahead — Hawaii’s popular sites and trails fill fast.
