Hiking To The “Lost Ark” – Lesser-Known 1KM Forest Hike Along The Green Corridor

Hiking to the Lost Ark in Alexandra Forest

Adventure isn’t always a plane ride away. Within Singapore, we’ve since unravelled the secrets of Maju Forest, the ins and outs of St John’s and Lazarus Island and of course, the serene trails of Clementi Forest. Below, we explore another hidden gem, the Lost Ark: an obscure wooden deck built out of a fallen tree in Alexandra Forest.

P.S. Don’t forget to be a responsible visitor: look after the amenities there, and pick up any litter left behind before leaving.

Hiking to the Lost Ark

Like many of the best hiking trails in Singapore, the Lost Ark isn’t easy to find. On Google Maps, you’ll find it tagged as “The Deck”’ with only a single review and a handful of images to its name. Obscure? Check. Thrilling? Check.

There wasn’t an abundance of information available online by any means which made us slightly worried about being the next lost-in-a-forest case. Fortunately, we were lucky enough to have a friend who’s been here before, to lead us to one of the many trailheads. Here’s our guide to a short but sweet ~1km hike via the Green Corridor at Alexandra:

Enter via the Rail Corridor, near Masjid Hang Jebat

The trailhead we were looking for starts near Masjid Hang Jebat – which in itself, is located in a rather ulu location. The nearest bus stops – Blk 19 and Opp Queen’s Cl – are both located a 700m or 10-minute walk away. Bus 61, 100, 123, and 855 are some of the more buses that you can take to get there.

After going past an overhead bridge, turn left and stroll down the scenic paths of the Green Corridor until you arrive at a white mosque – that’s Masjid Hang Jebat, your first landmark. Alternatively, you can also drive or take a Grab ride directly to the mosque.

An obscure entrance lies to the right of the mosque. And I know, a literal gap in a wall of trees doesn’t scream “trailhead”, but spritz on some mosquito repellent and head on in – you’ll soon find a clear path ahead.

The path bends and splits so we’d recommend turning on your GPS and referring to it as you head south. You’ll soon come across an opening in the forest – your 2nd landmark – and shortly thereafter, the Lost Ark. 

Fallen tree turned into a rustic deck

Despite being located within only a small patch of green between the AYE and Alexandra Hospital, the Lost Ark channels serious out-of-Singapore vibes – thanks to the fact that it’s almost completely surrounded by greenery.

Australia? Europe? This can be whatever escape you need it to be.

Built out of a massive fallen tree, the deck itself is a little worn but clean and sturdy. It’s also equipped with foldable chairs and wide wooden benches you can rest on to enjoy a picnic after the hike. 

With a sprinkle of imagination, the deck, with its pointy “bow” and wider “stern”, can be pictured as an abandoned raft washed ashore. If you’re ready to brave muddy paths, come after a heavy rain when the area tends to flood up. We hear that it is then, that the ark truly resembles a drifting raft on a river.

Interesting signs of life here include a wok hanging above a fireplace and mess tins packed neatly away in “storage sections” of the ark. 

According to Mr. Amrin Amin, the Lost Ark was originally built by a resident who lives in the area for his family to relax and enjoy the great outdoors. However, as it’s risen in popularity among the hiking community, there have been more instances of littering and pollution, as well as cases of deck chairs damaged by irresponsible visitors. 

Since this area is not maintained by NParks, it’s up to visitors to take good care of the area so remember to take any litter with you when you leave and avoid being loud as there are residents living in the nearby houses.

To exit, continue on the path heading south, and in a minute or so, you’ll emerge out of the forest into Warwick Road. Continue down the road and turn down Alexandra Road to arrive at a bus stop several attractions are located nearby including IKEA Alexandra.

Exploring the Lost Ark in Alexandra Forest

Of all the hiking trails we’ve found, the Lost Ark has to be one of the most unique. How often is it that you can find a fallen tree that hasn’t been cleared away, much less creatively converted into a hangout spot? 

Albeit hidden, a hike here isn’t particularly difficult with a short and rather flat trail. Still, don’t forget to wear proper shoes and bring along some water. We’ll also recommend bringing an umbrella and raincoat in case it rains.
