Kailua

Consistently rated one of the best beaches in America with soft white sand, turquoise water, and a gentle shore break that is perfect for kids. The water is warm and clear year-round and the beach stretches for 2.5 miles so you can always find space. Kayak rentals are available for paddling to the Mokulua Islands offshore. The park has restrooms, showers, lifeguards, and shady trees for picnics. Windsurfers and kiteboarders add entertainment for watching. The whole vibe is relaxed and family-friendly.

A short but steep 1.8-mile round trip hike to WWII military pillboxes (bunkers) on a ridge above Lanikai Beach with some of the most stunning views on Oahu. The turquoise water below with the Mokulua Islands in the foreground is postcard-perfect. Kids love exploring the old concrete bunkers covered in colorful graffiti art. The trail is steep and rocky in spots so good shoes are important. Sunrise from the first pillbox is legendary but the views are incredible at any time of day.

A jungle hike through lush windward forest to a beautiful waterfall with a deep swimmable pool at the base. The trail is about 3 miles round trip and crosses streams and roots through dense tropical vegetation. The waterfall drops about 20 feet into a clear pool where local families swim and jump from the rocks. The trail can be muddy and slippery so this is best for kids who are comfortable on rough terrain. The swimming hole at the end makes all the mud worthwhile.
