Beaches
Dream Beach
A wonderful secluded beach with powdery, white sand, located on the south coast. From the main accommodation areas on the west coast, head southeast towards Lembongan Village where you should turn west, and then look for the signposted small track leading south to Dream Beach. There is a cafe attached to the single resort here, and this makes Dream Beach a great place to spend the whole day doing nothing. Be very careful though about entering the water here as the rips can be fierce. Only the strongest swimmers should consider this and even then, avoid the eastern end of the beach.
Tamarind Beach
Good views back to Bali, and of Mount Agung especially.
Sandy Bay
A small but spectacular beach with white sand and crashing waves, located just to the north of Dream Beach, and easiest reached via the same route. The excellent Beach Club at Sandy Bay is located here and this should encourage visitors to spend the day. At low tide a dramatic cave is exposed in the low limestone cliff at the eastern side of the bay. Approach carefully and make sure you are not cut off from the beach by a rising tide. All-in-all, this is a delightful spot which is as laid back as anywhere in the whole of Bali.
Other
Mangrove Forest
Northern Nusa Lembongan has an extensive forest of mature mangroves which can be explored in a jukung outrigger boat. Also great for families at high tide as perfect lagoon for kids swimming.
Suspension Bridge
This quirky yellow suspension bridge should not be missed by any visitor. You can walk or bike across the bridge to neighbouring Nusa Ceningan. The noise it makes can be quite scary, and contributes to what is an all-round Indiana Jones-type experience. Although it is definitely getting more and more rickety as the years pass, the bridge is still safe, and there are many thousands of incident-free crossings every year. There are very rare occasions when the bridge is off-bounds to motorbikes due to maintenance. At such times boats, offer transport across the channel for you and your bike.
Sunsets
One thing not to miss on Nusa Lembongan. The Sunset over Bali is awe-inspiring, and can be viewed from any west facing part of the island, but the beach at Jungut Batu is especially popular. A more rural alternative is to go over the bridge to Nusa Ceningan and view the sunset from one of the west-facing high ridges. Being just a few degrees south of the equator, sunset times do not vary much throughout the year here. Look to be in place between 5:30PM and 6PM.
Seaweed Farms
Seaweed farming takes place in many parts of the island, but the most accessible farms are on the southern side of Lembongan Village. Most of the seaweed grown here is destined for the Asian cosmetics industry.
Puncak Sari Temple
The largest and grandest Hindu temple on the island. Good views over the straits back to Bali from this area.
The attractions here are mostly natural. The beaches and other coastal landscapes are obviously a key draw, as are the sunsets. There are a limited number of man-made attractions, most notably temples and the rickety suspension bridge.
nusa ceningan
Nusa Ceningan is the tiny island between Nusa Lembongan and Nusa Penida, which is easily reached via the suspension bridge on foot or by bicycle/motorbike. There is a notable surf break off Nusa Ceningan which attracts some surfers away from the more crowded breaks on Nusa Lembongan. Otherwise the island offers some scenic roads and paths, and the westward views back over Nusa Lembongan to Bali are impressive. Viewing the sunset over Bali from the central Ceningan ridge is very much worth the effort. The estuarine channel between Lembongan and Ceningan is home to many seaweed farms.
Very few visitors choose to stay on Nusa Ceningan, but a small bungalow complex opened in 2009, another in 2010, and more accommodation options are in the pipeline.
