Visit Carlsmith Beach Park: Four Mile in Hilo and one of the most unusual and gorgeous places in Hawaii (updated 2023)

Carlsmith Beach Park (Also known as Four Mile) is simply gorgeous Located along the string of small beach parks that skirts the coastline from downtown Hilo and past the Hilo airport, Carlsmith beach is interesting and a very popular local beach. But it is different to the other beach parks in that it doesn’t have a real beach! Instead what substitutes for beach is green lush lawn and flat lava rocks that everyone parks their towels in. What makes this beach stunning is the soft beach bottom and gorgeous aqua to azure tones of green to blue within the lagoons, coves and a outer rock barrier that protects in inside reef and lagoons which are fun to swim, snorkel or kayak in..

Why it is also called 4 Mile Beach?

Carlsmith is called “4 mile” because it is about four miles from the downtown area of Hilo. It is also next to James Kealoha (4-mile) Beach Park and the entire area is referred to as 4 mile so there’s no confusion to the different named parks close by to each other. Carlsmith is located on the ocean side with the pool lagoons and before James Kealoha Beach with the large parking lot area and a private fish pond on the far left side of the park area.

A family friendly beach park, the protected reef feels like a giant swimming pool on one end and a bay with little islands sprinkled in the middle that make it a fun destination. The shallow lagoon portions and cove areas are perfect to little kids to play in under the parent’s eyes that can easily spot them from above in the green lawn areas of the park.

Protected break waters & family fun at Carlsmith

Carlsmith beach is a family friendly swimming post. Perfect for snorkeling fun, bringing big play toys like sup boards and kayaks, there’s plenty of space to float and explore around 4 mile beach. The beach has fresh water bubbling to the surface mixing cold and hot water giving swimming an odd but refreshing experience passing through these areas.

There are picnic tables around the park to set up or you can lay a towel on the large grassy lawn area. The area also has lots of coconut trees and large shrubby areas to protect from the hot afternoon sun around the beach areas.

Weather and best time to visit Hilo, Hawaii

Hilo, Hawaii, enjoys a tropical rainforest climate with warm temperatures and high humidity year-round. When considering the best time to visit, it’s essential to understand the distinct seasons and weather patterns:

Winter (November to March): This is Hilo’s wet season when it receives the most rainfall. Expect frequent showers and occasional heavy downpours. Despite the rain, the temperatures remain warm, making it a great time for exploring lush landscapes and experiencing the vibrant greenery.

Spring (April to June): Spring in Hilo offers more stable weather compared to the wetter months. While there may still be occasional rain, you’ll also enjoy plenty of sunshine. This period is excellent for outdoor activities like hiking, waterfalls, and exploring gardens.

Summer (July to September): Hilo’s summer is warm and relatively dry compared to the winter months. July is typically the driest month of the year. It’s an ideal time for beach outings, snorkeling, and enjoying the sun.

Fall (October to early November): Fall sees a transition back to wetter conditions, although it’s not as rainy as the winter months. The weather remains warm, making it a pleasant time for exploring the area.

Hurricane Season (June to November): Hilo is prone to hurricanes during this period. While direct hits are rare, it’s essential to stay informed about weather updates if you plan to visit during hurricane season.

In terms of the best time to visit Hilo, it largely depends on your preferences:

  • For Lush Scenery: Visit during the wetter months (winter and fall) when rainfall makes the landscapes incredibly green, and waterfalls are at their fullest.
  • For Sunshine: Opt for the drier months (spring and summer) when you’re more likely to experience consistent sunshine for outdoor activities.
  • For Whale Watching: If you’re interested in whale watching, plan your trip between December and April when humpback whales migrate to Hawaiian waters.

Keep in mind that Hilo’s weather can be unpredictable due to its rainforest climate, so it’s always a good idea to check the local forecast and be prepared for occasional showers no matter when you visit.
