Pro Tips

  1. 1.Arrive early (right at 9 AM opening) to avoid afternoon rain showers that are common in Manoa Valley and to beat any tour groups
  2. 2.Wear closed-toe shoes with good traction,trails can be muddy and slippery even when it hasn't rained recently
  3. 3.Bring bug spray and rain jackets; the rainforest environment means mosquitoes and sudden showers are common
  4. 4.Stop by the visitor center first to grab a trail map and ask about any kid-friendly programs or scavenger hunt activities happening that day
  5. 5.The Aihualama Trail leading to the waterfall is about 0.8 miles one-way,a manageable adventure for most school-age kids

Best Time to Visit

Visit on weekday mornings (Monday-Thursday) between 9-11 AM for the best weather conditions and fewer crowds. Mornings offer cooler temperatures and clearer skies before the typical afternoon Manoa showers roll in.

What to Know

Admission is $5 per person (kids under 12 free), cash or check only. Parking is limited to a small lot at the entrance, so arrive early. There are no food facilities on-site, so pack snacks and water, and restrooms are available near the visitor center.

Seasonal Notes

Open Monday-Friday only (closed weekends and holidays). Winter months (November-March) bring more frequent rain but also lusher vegetation and fuller waterfalls. Summer offers more reliable dry mornings but still expect occasional showers,it's a rainforest after all!

Nearby Eats

Head back down Manoa Road to Puka Dog (10 minutes away) for kid-friendly Hawaiian-style hot dogs, or visit Andy's Sandwiches & Smoothies (5 minutes) for healthy wraps and fresh fruit smoothies that kids love after a morning hike.
