Established in 1992 to protect the wetland habitat of two endangered wetland birds, Keālia Pond National Wildlife Refuge encompasses approximately 700 acres and is one of the few natural wetlands remaining in the Hawaiian Islands. It is the largest lowland wetland remaining on Maui. Keālia Pond is located along the south-central coast, between the towns of Kīhei and Mā‘alaea, it is a natural basin for a 56-square mile watershed from the West Maui Mountains. The Keālia Coastal Boardwalk is a beautiful tranquil walkway and bird sanctuary, beside Mā‘alaea Bay on the south edge of Maui's central valley. A walk on the boardwalk takes you through ancient wetlands where you can watch two of Hawaii's native and endangered waterbirds - the Hawaiian coot and Hawaiian stilt. Across the highway you can see Keālia Pond where waterfowl from Asia and North America come for rest and warmer climate, including northern shoveler and northern pintail. The Pacific golden plover migrates from Alaska, and other birds that come for the winter are the wandering tattler and ruddy turnstone. The seasonal conditions that occur at Keālia Pond National Wildlife Refuge make it a notable place for people to observe Hawai‘i's endangered wetland birds, along with a diversity of feathered visitors from as far away as Alaska and Canada, and occasionally from Asia.

What to Pack for Keālia Pond National Wildlife Refuge, Maui

A well-packed bag handles most of what this area can throw at you.

What you bring to Keālia Pond National Wildlife Refuge matters. This list reflects the actual conditions you'll encounter.

Essential

Water (minimum 2L) — Water sources marked on maps may be seasonal or dry; carrying enough to complete your route prevents a dangerous shortfall.
Navigation (map/GPS/compass) — Getting lost is the leading cause of backcountry search-and-rescue calls; reliable navigation prevents the situation entirely.
Sun protection (sunglasses, sunscreen) — Prolonged sun exposure causes headaches, fatigue, and heat exhaustion that can cut a trip short or create a medical emergency.
First aid kit — Remote locations mean longer response times for help; a first aid kit bridges the gap between injury and professional care.
Extra food — High-energy snacks weigh little but provide crucial fuel if you need to bushwhack out or wait for conditions to improve.
Headlamp with extra batteries — Hands-free light is essential for navigating uneven terrain, setting up camp, or signaling for help at night.
Fire starter — Waterproof matches or a ferro rod weigh almost nothing and can be the difference between a cold night and a survivable one.
Emergency shelter (space blanket) — Wind and rain strip heat faster than most people realize; a compact emergency shelter blocks both.
Knife or multi-tool — A multi-tool handles problems you can't predict: jammed zippers, tangled line, first-aid tape cutting, or gear fixes on the trail.
Extra clothing layer — A lightweight fleece or puffy stuffs small but provides critical insulation if temperatures drop unexpectedly.
