MERCER BAY LOOP LOCATION
Mercer Bay Loop is located in the Waitākere Ranges on Auckland’s west coast, overlooking the Tasman Sea. The track sits between Piha, Karekare, and Whatipū, making it an easy add-on to a wider West Coast day trip.
HOW TO GET TO THE MERCER BAY LOOP TRAILHEAD
The Mercer Bay Loop trailhead is roughly a 38 km drive from Auckland CBD, taking around 45 minutes depending on traffic.
After leaving SH16, you’ll pass through Henderson before turning onto Piha Road. From here, the drive becomes part of the experience. Dense native forest, winding roads, with little sneak peeks of views along the way.
A quick heads-up: some sections of Piha Road are narrow, with occasional one-way bridges. Take it slow and enjoy the scenery.
A few things to know before you arrive:
- Log Race Road is unsealed and has potholes, so drive carefully, especially in low-clearance vehicles.
- The road into the carpark is one way, which can slow things down when it’s busy.
- Early mornings and evenings are your best bet if you want an easier park.
Parking tips
The entrance to Mercer Bay Loop sits just off Piha Road. You’ll turn onto Te Ahuahu Road, which becomes Log Race Road, leading to a small cul-de-sac style carpark at the end.
Parking is free but limited. During busy periods, you may need to loop back or wait for a space to open.
KEY INSIGHTS FOR WALKING MERCER BAY LOOP
Distance: 2.1km | 1.3 miles
Elevation: 154m
Duration: 30-45 minutes
Difficulty: Easy
Trail Type: Loop
Open: Year-round
Mercer Bay Loop might be short, but it wastes no time delivering the goods.
As a loop track, you can walk it in either direction. I recommend going anti-clockwise. This way, you tackle the stairs and downhill sections first, saving the steady climb for the return. It’s still steep in places, but it feels more balanced overall. I also think the views open up more naturally in this direction.
The track is well formed and clearly marked, making it suitable for most fitness levels and families. Fencing lines much of the route, which adds reassurance near the cliff edges, though there are still sharp drop-offs. Keep kids close and stay aware of your surroundings.
As you follow the coastline, the views stretch out across Piha, Karekare, and Whatipū. On clear days, the Tasman Sea feels endless. The track is exposed in places, so expect wind and sun, especially in the afternoon.
Despite its popularity, Mercer Bay Loop never feels rushed. There are plenty of natural pauses along the way, perfect for soaking it all in or grabbing photos.

BEST TIME TO VISIT
Early morning and late afternoon are hands-down the best times to walk Mercer Bay Loop. Mornings are quieter, cooler, and calmer. Late afternoon brings warmer light and dramatic skies, especially if you’re there for sunset.
Midday tends to be busier, particularly on weekends and during summer. If that’s your only window, it’s still worth doing, just expect company.
HOW CROWDED DOES IT GET
This is one of Auckland’s more popular short walks, so it does get busy and timing does matter.
Early starts feel relaxed and spacious. Late mornings and early afternoons can feel busy, especially near the carpark and lookout points. Even at sunset (my favourite time to visit) it still can be quite busy but if you pick outside of busy season and on a weeknight, you’ll have less people to battle with.
However, the good news? Because it’s a loop, people spread out quickly, and it rarely feels overwhelming, no matter what time you visit.
IS MERCER BAY LOOP SAFE TO WALK SOLO
Yes. I’ve walked Mercer Bay Loop solo a couple times and always felt comfortable.
The track is clear, well maintained, and close enough to civilisation that it doesn’t feel remote. That said, there are reports of people going missing near this track, and it’s unknown as to why but if this makes you uncomfortable, best to stick during daylight hours when there are plenty of others around. It’s also still a cliff-top coastal walk. So make sure to stick to the track, watch the wind, and let someone know your plans if you’re heading out alone.
OTHER PINS YOU MIGHT LIKE
THE WAITĀKERE RANGES
The Waitākere Ranges are a favourite of mine when needing to get out of the city. There’s so many great places to get outdoors, into nature for a walk or even just a sunset mission. Mercer Bay Loop obviously offers great opportunities for both, but if you’re keen on exploring more around the area, I highly recommend checking out the Omanawanui Track. Spend the afternoon walking this trail and follow it up with a sunset at Whatipu beach.
If you’re wanting to explore even more of Aucklands Waitākere Ranges, here are 6 of the best walks that I highly recommend. Or, alternatively if you’re just wanting some easy lookouts that don’t require much energy to get to, here are some of my favourite Waitākere Ranges lookouts too.

Staying out here lets you enjoy the coast early and late, when it’s at its best.
CONCLUSION
Mercer Bay Loop is one of those walks that quietly delivers every single time. Short, scenic, and wildly beautiful, it packs the best of Auckland’s West Coast into less than an hour.
Whether you’re chasing golden hour, stretching your legs between beach stops, or showing visitors just how rugged Auckland can be, this loop never disappoints. The cliffs, the ocean, and that open Tasman horizon do most of the talking.
