If you’re planning to visit the island of Kauai, you’re probably wondering whether you need to book anything in advance.
Obviously there are the flights and hotels, but what about state parks and other activities? Thankfully most things in Kauai don’t require a reservation, but there are a few exceptions.
This travel guide will give some tips for how far in advance you should book your Kauai activities. It’s based on my own experience!
Summary: What & When To Book
Here’s a quick summary of when you may want to book ahead for things in Kauai:
- Kalalau Trail — Reserve 1-3 months in advance
- Ha’ena State Park / Ke’e Beach — Reserve 1-4 weeks in advance
- Special Tours — Reserve 1-2 months in advance
- Botanical Gardens — Reserve 1-2 weeks in advance
- Restaurants (Fine Dining) — Reserve 1-2 weeks in advance
- Kilauea Lighthouse — Reserve same week
- Hanalei Bay — No reservation needed
- Koke’e State Park — No reservation needed
- Wailua River State Park — No reservation needed
- Waimea Canyon State Park — No reservation needed
Note: This is just general guidance, and things can change a bit depending on the hour, day, week, and month when you travel.
Kauai is busiest in the summer (June to August) and the winter holidays (December to January), so you may want to book earlier if you’re traveling at those times, especially for weekends or peak hours.

Things You DO Need To Book In Advance
• Kalalau Trail
The Kalalau Trail is one of Hawaii’s most sought after hikes, and camping reservations open 90 days in advance.
The permits are hardest to get in the spring or summer months, because the weather is best and it’s a busy time for tourism in general on the island.
During summer, permits sell out within minutes when they become available on the website, so remember to create your account ahead of time and be logged in 5-10 minutes before permits become available.
Demand is so high the state sometimes adds extra seasonal capacity (e.g. +20 permits per night in summer), and additional permits may be available to walk-in applicants at the State Parks office in Lihue.
If you’re hiking in the winter months, however, permits are much easier to get. I’ve actually booked Kalalau permits on the same week as my hike before, although I’d still recommend booking a month in advance if possible.
Keep in mind, even if you have a camping permit for the Kalalau Trail, you also need a separate permit to park overnight at the trailhead. However, you can skip that if someone is dropping you off there.

• Ha’ena State Park
Permits are now required to enter Ha’ena State Park, visit Ke’e Beach, or hike the first 2 miles of the Kalalau Trail (as a day hike to Hanakapiai Beach/Falls).
These permits open for sale 30 days in advance, and the two main options are a parking pass that allows you to drive in to Ha’ena with your own vehicle, or a shuttle pass starting from either Waipa or Princeville.
The parking passes sell out almost instantly when they become available, so you’re unlikely to snag one unless you keep checking back later and there’s a cancellation.
The shuttle passes are much easier to get. There’s usually plenty of availability, so you can safely book them the week before.

A day use permit for Ha’ena State Park allows you to hike the first 2 miles of the Kalalau Trail without a camping permit.
• Special Tours
If you plan to do any special activities or tours in Kauai, those should be booked well in advance.
For something like a scenic helicopter ride or a boat tour of the Na Pali coast, I’d recommend booking 1 to 2 months out; maybe more if there’s a certain time slot you’re wanting, such as early morning or sunset.
Remember to schedule any important tours for the start of your trip, that way you’ll have room to reschedule it later if it’s canceled because of weather.

• Botanical Gardens
There are a bunch of different botanical gardens in Kauai to choose from, so if you’re not picky about which one to visit, it’s safe to book this a week in advance.
Otherwise, if you have a specific garden in mind, or your schedule is tight, then I’d book it 2 weeks in advance.
Some of the gardens include a tour in the price, while others allow you to visit self-guided.
Book Now:
• Restaurants (Fine Dining)
A few well-known eating spots in Kauai recommend reservations:
- Bar Acuda
- Beach House Restaurant
- Eating House 1849
You should be safe booking these 1 or 2 weeks ahead. If you plan to do a Luau (traditional Hawaiian feast), you’ll want to book ahead for that too.
Casual restaurants and food trucks usually don’t require any kind of reservations.
• Kilauea Lighthouse
Since 2022, a reservation is required to visit Kilauea Point and the lighthouse. You can book it online before you go.
The good news is that the tickets are relatively cheap by Hawaiian standards, and even the most popular time slots rarely sell out, so you can safely make a reservation on the same week of your visit.
If you have an ‘America the Beautiful’ pass (aka National Park Senior, Annual, Military, 4th Grade, and Access), those are also accepted here.

Things You DON’T Need To Book In Advance
Most things in Kauai still don’t need to be booked in advance.
That includes Hanalei Bay and the state parks like Koke’e, Polihale, Wailua Falls, and Waimea Canyon.
Parking passes are now required for Koke’e and Waimea, but they’re unlimited and you can buy them on the spot.
Aside from the Kalalau Trail, most hiking trails in Kauai can also be done without any permits or reservations.
