Kanaha Beach Park
This area is known as a major kiteboarding and windsurfing area with steady trade-winds and some nice offshore surf when the conditions are right. This is also true for most of the north shore beaches but this area has long sandy beaches and decent parking. Steady trade winds along this northern shoreline are some of the best ocean sports conditions in the world. This is why a lot of the watersport instruction happens with windsurf and kite-board rental trucks parked right up to the beach. There are bathrooms here but they are near the first entrance parking lot which is a bit of a walk from the beach. Kanaha Beach is a beautiful stretch of sand broken up with occasional lava rock outcroppings.
Kahana Beach runs from Kahului Harbor all the way to Paʻia. Kahana Beach Park is next to the airport and is a great place to start a good beach walk.
Kahana is a kite boarding area and even though you might have to cut inland a little you’ll rarely lose sight of the beach. It is quite remote until you get to the Spreckelsville area where you’ll find Baby Beach and Baldwin Beach parks. This shoreline has small coves protected by rock outcroppings so wear some shoes or sandals you can take off while on the sand and put on to climb the sharp lava rocks. Depending on where you start and end this can be a ½ day or full. Bring water and a towel in case you decide to go swimming. Be careful though as the North Shore is exposed to open ocean and can have a nasty undertow and hidden rocks and stumps just off the beach.
