A rare Lembeh site that mixes a small coral wall with a critter-rich sand slope.
Nudi Falls is one of the more varied sites in the strait, which is why it is so popular. It starts with a small wall covered in sea fans and soft coral, then drops onto a sandy slope, so you get a bit of reef colour alongside the usual muck life.
The name comes from the nudibranchs that seem to tumble down the wall, and they are everywhere here in odd shapes and colours. The fans hold pygmy seahorses if your guide knows where to look, and the slope below turns up frogfish, octopus, ribbon eels, and crustaceans.
There can be a touch more current than the flat muck sites, but it stays manageable. The mix of wall and sand makes it a good all-round Lembeh dive.
Getting there
Nudi Falls sits in the Lembeh Strait near Bitung, roughly 90 minutes by road from Manado and then a short boat hop arranged by your Lembeh resort or operator. It is a regular stop on most local dive schedules as a guided dive.
Best time
Diveable all year, with the calmer months around June to October giving easier surface conditions. Slack tide is the gentlest window if you want minimal current on the wall.
Good to know
Ask your guide to point out the pygmy seahorses on the fans, as they are tiny and easy to miss, and never touch the fans to steady yourself. Keep an eye on the mild current near the wall and stay off the coral with good buoyancy.
It is a mix, which is what makes it stand out in Lembeh. You get a small coral wall with fans plus a sandy critter slope below, so it offers both.
Often, if your guide knows the resident sea fans. They are extremely small and well camouflaged, so a good spotter makes all the difference.
Usually mild to moderate, a little more than the flat muck sites. With basic buoyancy and a guide it is comfortable, and diving slack tide keeps it calm.
