The Kalalau Trail on Kauai starts at Ke’e Beach and runs 11 miles along the Na Pali Coast — one of the more demanding hikes in Hawaii, with permits required beyond the 2-mile day-hiking mark. It’s a useful entry point for this itinerary because it sets the tone: this is a trip built around outdoor activity first, with beaches and scenery as the reward for getting there. Across three islands — Kauai, Maui, and the Big Island — there’s enough hiking, snorkeling, kayaking, and lava-field walking to fill 10 days without repeating yourself.
The order matters. Kauai is widely considered the top island for outdoor adventure and hikers, so it makes sense to open there when energy is highest. Maui comes next for the Road to Hana, Haleakalā, and Molokini. The Big Island closes the trip — its landscapes are more remote and require more driving, which suits the end of a trip when you know your rhythm. Here’s how to structure the 10 days.
Kauai’s Kokeʻe State Park alone contains over 45 miles of hiking trails through canyons and valleys — and that’s before you add the Na Pali Coast, Waimea Canyon, and the Wailua River kayak routes.
Ten days across Kauai, Maui, and the Big Island is realistic for active travelers who don’t mind full hiking days. The main pacing risk is Haleakalā sunrise — it requires advance reservations and a very early start from wherever you’re staying on Maui. If that’s too uncertain, substitute the Sliding Sands Trail during the day, which doesn’t require timed-entry permits.

Here’s the full 10-day shape before we break each leg down.
| Days | Island / Area | Main Activity | Time | Key Tip |
|---|---|---|---|---|
| 1–3 | Kauai — Na Pali, Waimea Canyon, Wailua Valley | Kalalau Trail (2-mile day hike), canyon hiking, kayak to Secret Falls | Full days | Kalalau Trail day hiking is allowed to mile 2 without permits — the Hanakapi’ai Beach turnaround is a solid 4-mile roundtrip |
| 4–6 | Maui — Hana, Haleakalā, Molokini | Road to Hana, crater hiking, half-day snorkel tour | Full days | Haleakalā sunrise requires advance reservations; the Sliding Sands Trail hike doesn’t and gives similar crater views |
| 7–10 | Big Island — Kona, Volcanoes, south coast | Manta ray night snorkel, Volcanoes National Park, Green Sand Beach hike, Mauna Kea stargazing | Full days | Papakolea Green Sand Beach requires a 5.6-mile roundtrip hike — don’t attempt it as a late-day add-on after Volcanoes |
Now let’s get into each island in detail.
Which Island to Start On — and Why
Trail hikers
Kayakers
Nature-first travelers
Starting on Kauai makes logistical sense. You fly into Lihue, rent a car, and the island’s two main outdoor zones — the Na Pali Coast in the north and Waimea Canyon in the southwest — are both easy drives from there. The island is compact enough that you can hit both in three days without rushing. Na Pali is where most people spend the most time, so front-loading it on fresh legs pays off.
Hiking trails in Kokeʻe State Park alone — before counting the Na Pali coast, Kalalau Trail, or Wailua Valley routes.
Kauai rewards travelers who are comfortable with a car and don’t need hotels near a commercial strip. The north shore — Ke’e Beach, Hanalei Bay, and the Queen’s Bath volcanic coastline walk — is one coastal drive from the east side of the island. The southwest is a separate trip: Waimea Canyon, Kokeʻe State Park, and the Kalepa Ridge Trail for cliff views. Plan on spending two nights on the north shore and one on the west side, or drive between them as day trips from a central base.
The Outdoor Itinerary by Island
Kauai — Na Pali, Waimea Canyon, and the Wailua Valley
Day 1 on Kauai should go straight to the Kalalau Trail at Ke’e Beach on the north shore. Day hiking is permitted to the 2-mile mark without permits, turning at Hanakapi’ai Beach for a 4-mile roundtrip with coastal views across the Na Pali cliffs. If you want to go further, overnight permits are required for the full 11 miles. Raft tours and catamaran tours also access the Na Pali sea caves and waterfalls from the water — the raft gets closer to the caves but is a rougher ride. Helicopter tours give you the aerial perspective without hiking. On Kauai, the north shore also has Tunnels Beach, a snorkeling spot with a coral reef and sea turtles a short drive from Ke’e.
Day 2 works well as the Waimea Canyon and Kokeʻe State Park day. Waimea Canyon is a roughly 45-minute drive from the island’s west coast — the canyon is often called the “Grand Canyon of the Pacific,” though the comparison undersells how different the landscape feels. Hike the Kalepa Ridge Trail for cliff-edge views, or take one of the easier Kokeʻe trails first before committing to a longer ridge route. Wailua Valley — kayaking the Wailua River to Secret Falls or Wailua Falls — makes a good Day 3 before flying to Maui. Kapa’a on the east side also has a coastal bike path if you want something lower-impact before the island transfer. This connects naturally to the fuller breakdown of how to plan a Kauai trip without overloading the schedule.
Maui — Road to Hana, Haleakalā, and Molokini Crater
The Road to Hana is a 64-mile route from Kahului that takes a full day if you stop properly. Key outdoor stops along the way include Wai’anapanapa State Park’s Black Sand Beach with its sea stacks and lava caves, and Na’ili’ili Haele Stream for a bamboo forest hike to cascading waterfalls. Kaihalulu Red Sand Beach — a crescent cove colored by lava cinder cliffs — is worth the detour into Hana town, but the hike is recommended for experienced hikers only: the path is narrow and can be slippery. The Kipahulu Visitor Center at the end of the road accesses the Seven Sacred Pools and the Pipiwai Trail to Waimoku Falls through bamboo forest.
Haleakalā deserves its own day. The summit sits at 10,023 feet and sunrise viewing requires advance reservations — without one, you’ll be turned away at the gate. The Sliding Sands Trail descends into the crater and doesn’t require timed-entry, making it a strong substitute if reservations aren’t available. Allow the full morning for the crater, then head back down to the coast for Molokini Crater in the afternoon via a half-day boat tour — it’s a 230,000-year-old half-submerged volcanic crater with calm, clear water ideal for snorkeling. The tour boats typically depart from Maalaea Harbor on the south side of the island, which is well-positioned after a Haleakalā morning.
At Kaihalulu Red Sand Beach in Hana, the access path starts near the Hana Community Center and descends a cliff trail on crumbly lava rock. Go in the morning before afternoon foot traffic and wear closed-toe shoes — sandals make the descent genuinely risky.
Big Island — Volcanoes, Manta Rays, and Remote Coastline
The Big Island rewards patience and driving. Hawaii Volcanoes National Park is the centerpiece — the Kilauea crater, Chain of Craters Road, and Thurston Lava Tube (Nakuha) can fill most of a day. The lava lake inside the active caldera is most dramatic at night when the glow is visible. Punalu’u Black Sand Beach, a sea turtle sanctuary, is a natural stop on the south coast drive between Hilo and Kona, about 40 minutes past the park entrance. Papakolea Green Sand Beach — olive-colored sand derived from olivine mineral — is a 5.6-mile roundtrip hike from the parking area near South Point. Treat it as a standalone half-day, not a tack-on to a Volcanoes day.
Kona on the west side is where the marine activities live. The Captain Cook Monument in Kealakekua Bay offers vibrant coral gardens and tropical fish via a morning boat tour — accessible by guided snorkel trip or kayak. The Manta Ray Night Snorkel at Makako Bay near Kona is one of the more unusual experiences on any Hawaiian island: manta rays feed at the surface after dark, drawn by dive lights. It’s a guided experience that typically runs a couple of hours. Mauna Kea’s summit at 13,796 feet is a stargazing destination; tours depart from the visitor center at around 9,200 feet, and the drive up requires a 4WD vehicle above the mid-mountain elevation.
Planning the Island Hops and Managing Your Energy
Getting Between Islands
You’re moving Kauai → Maui → Big Island. Interisland flights run roughly 40–55 minutes gate to gate, but the full door-to-door process — car return, check-in, flight, baggage, new car pickup — takes closer to 3–4 hours. Budget half a day for each island transfer and plan lighter activity that afternoon. Fly open-jaw: into Lihue (LIH) on Kauai and out of Kona (KOA) on the Big Island, with Maui in between via Kahului (OGG). That routing avoids backtracking. Each island requires its own rental car; they can’t travel between islands. A standard car handles Kauai and Maui fine; the Big Island benefits from a jeep or AWD vehicle if you’re doing Mauna Kea or the South Point access road.
Activity Permits and Advance Reservations
Two activities require advance reservations that can’t be sorted at the gate. Haleakalā sunrise viewing is one — the park’s sunrise tours require pre-booking and sell out weeks ahead during peak months. The Kalalau Trail beyond mile 2 requires overnight permits. Day hiking to the 2-mile mark is open without a permit. Hanauma Bay on Oahu (not on this itinerary but a common add-on) also requires advance online reservations and charges $25 entry. Book Haleakalā and any guided boat tours — Molokini, Captain Cook Monument, manta ray night snorkel — before you leave home.
Diamond Head on Oahu now requires advance reservations for out-of-state visitors. If Oahu is a day stop between islands, verify the current reservation requirement before planning a Diamond Head hike as a spontaneous add-on — walk-ups may not be permitted on busy days.
- Haleakalā sunrise and the Kalalau Trail overnight both need advance arrangements — sort these before booking flights, since they may dictate which days you’re on each island.
- Papakolea Green Sand Beach is a 5.6-mile roundtrip hike from the parking area near South Point — plan it as a standalone half-day, not an add-on to a Volcanoes day.
- Flying open-jaw (into Kauai, out of Kona) removes a redundant return flight and works naturally with the Kauai → Maui → Big Island sequence.
What to Pack and Know Before You Go
Gear That Earns Its Weight
An active 10-day itinerary across three islands covers a serious range of terrain — lava fields, crater hiking, ocean snorkeling, canyon trails, and river kayaking. Carrying everything in one pack without checking bags (which saves money and time at island transfers) requires some thought. Waterproof everything that matters. A dry bag handles the Wailua River kayak and any boat tours. Hiking shoes that can double as water shoes reduce what you’re carrying. Reef-safe sunscreen is legally required in Hawaii — buy it before you go or it’ll cost more at the airport shops.
A quick heads up — some links here are affiliate links. If you buy through them, it costs you nothing extra but earns IslandHopperGuides a small commission. Honestly, that’s a big part of what funds the travel and research that goes into guides like this one. As an Amazon Associate, we earn from qualifying purchases — and I really do appreciate the support.
For an itinerary this varied, a waterproof action camera covers both the snorkeling at Molokini and the lava hikes at Volcanoes in one package. The DJI Osmo Action 6 is waterproof to 20 meters and mounts cleanly to snorkel masks and helmet straps, with reviewers noting it handles both hiking footage and underwater work well. For tracking active days across multiple islands, a multi-sport GPS watch that handles elevation, route mapping, and dive depth in one device reduces what you need to carry. The Garmin Fenix 8 Solar covers hiking, snorkeling (rated to 40m), and has a 48-day battery on solar — one less thing to charge between islands.
Questions outdoor travelers ask about a Hawaii activity trip
Which Hawaiian island has the most outdoor activities?
Kauai has the highest concentration of hiking trails, with Kokeʻe State Park alone containing over 45 miles of routes, plus the Na Pali Coast, Waimea Canyon, and Wailua Valley. The Big Island has the widest variety — volcanoes, lava fields, green and black sand beaches, manta rays, and Mauna Kea stargazing — but the distances between activities are larger.
For hikers specifically, Kauai is the stronger choice. For travelers who want a mix of hiking, snorkeling, and unique geological experiences, the Big Island is harder to beat on variety.
Do you need permits for the Kalalau Trail?
Day hiking to the 2-mile mark (Hanakapi’ai Beach) doesn’t require a permit. Going further — to Hanakoa Falls or the full 11 miles to Kalalau Beach — requires an overnight permit, which must be obtained in advance through Hawaii’s DLNR system.
Permits for the Kalalau Trail sell out quickly during peak months. If you’re planning an overnight beyond mile 2, check availability before finalizing your Kauai dates.
Is the Haleakalā sunrise worth the logistics?
It depends on how much advance planning you can do. The summit sits at 10,023 feet and sunrise viewing requires a timed-entry reservation booked well ahead, particularly in spring and summer. If reservations aren’t available, the Sliding Sands Trail hike into the crater during the day gives you a comparable view of the volcanic landscape without the 3 AM alarm.
The sunrise itself is genuinely striking — cloud inversion often puts you above the clouds at dawn. The complication is the planning overhead, not the experience itself.
Is the Papakolea Green Sand Beach hike worth it?
Yes, if you plan it correctly. The beach requires a 5.6-mile hike from the parking area near South Point, and the trail is exposed with limited shade. The olive-green sand from olivine mineral is genuinely unusual — there’s nowhere else quite like it in Hawaii.
The mistake is trying to do it as an afternoon add-on after Volcanoes National Park. Give it its own half-day and do it in the morning before the heat builds. A vehicle shuttle from the parking area is sometimes available from locals on-site, but it’s not guaranteed.
Can you do the manta ray night snorkel without diving experience?
Yes. The Manta Ray Night Snorkel at Makako Bay near Kona is typically a surface experience — you float on the water holding a board with lights while manta rays feed below you. No diving certification is required for the snorkel version, and guided tours handle all the equipment and briefing.
The dive version involves descending to the bottom and watching from below, which does require certification. Most operators run both options on the same tour, so you can book snorkel-only without committing to a dive.
Closing
Three islands in 10 days is a lot of moving around, but the activity variety justifies it — Kauai’s hiking terrain, Maui’s road and crater experiences, and the Big Island’s volcanic landscape are different enough that each island genuinely earns its place in the sequence. Hikers and trail runners will likely want more time on Kauai; snorkelers will find the Big Island’s Kealakekua Bay and the manta ray night experience worth protecting on the schedule. The trip works best as a point-to-point — don’t backtrack to Kauai or Oahu at the end.
