View humpback whales

Kauai is a great place to see whales. The island’s warm waters and gentle currents make it a favorite resting place for humpback whales, which travel thousands of miles yearly from their feeding grounds in the Arctic to their birthing waters in the south Pacific.

Whale watching season runs from mid-December through April, and peak times are January through March. Although the best way to watch whales would be via boat tours, those trips can be expensive so if you are on a lower budget, you may want to try spotting them from the shore. To do so, the best places you can go are Hanalei Bay, Poipu Beach, and Kealia Beach.

Take a picnic

Picnics are among the unique things to do in Kauai without spending a dime. Just grab some sandwiches, a little dessert, a couple of bottles of water or soft drinks, and head to one of these great Kauai picnic spots:

  • Poipu Beach Park offers plenty of space to spread out and enjoy your lunch. The water is shallow, so it’s safe for kids to play in the waves or the sand. There is a great sunset view here and you can see many Hawaiian sea turtles that come to rest on the beach in the evening.

  • Kiahuna Plantation’s beach is an excellent choice if you’re looking for something more secluded. It is just 5 mins drive away from Poipu but less crowded making it excellent for couples and seniors who want to relax.
  • Kuilau Ridge Trailhead has a picnic shelter just one mile up. It is a fairly easy but enjoyable hike.

Go wildlife watching

Wildlife spotting is a great way to enjoy Kauai’s natural beauty, and it’s free! You can easily spot wildlife as you drive along the island’s main roads, at its beaches or even on some of the walking trails.

One excellent spot to see some native species is Kokee State Park. It is home to chickens, wild pigs, dears, and goats.

Nene Hawaiian Goose

If you’re into birds or want to learn more about them, Kauai is heaven for birdwatching enthusiasts too. A wide variety of birds can be spotted in their natural habitat like hummingbirds, finches, warblers, and the state bird of Hawaii, the Nene Goose.

Try out local foods

Kauai is a paradise for food and it would be a shame to miss out on trying traditional Hawaiian dishes that are made with fresh local ingredients.

The best (and most affordable) way to do this is by visiting farmers markets where you can get some locally grown fruit, vegetables, and homemade delights such as jams, sauces, and baked goods at low prices.

You can also find roadside stands along significant roads. Most have plenty of seating areas to relax with snacks and drinks while enjoying the scenery. Should you go for a restaurant dinner, try local Kauai dishes like Lomilomi salmon (salted raw salmon served with tomatoes and onions) and Huli huli chicken (Hawaii-style barbeque chicken).

There are plenty of free things to do that won’t cost you a single cent, while others that are affordable and usually under $10.
