There is a hospital and enough local shops to buy items of basic necessity.

It takes about five/six hours by car from Berau to get to Biduk-Biduk. There is a bus terminal where you can take a shared car for aprox. 150 000IDR per person or charter a private one for around 800 000IDR per car. Hotels can organise a pick up as well. It is also possible to get a transport to Biduk-Biduk from Samarinda or Balikpapan but it is a tiring journey of 20 hours or more. The price of a shared car is around 450 000IDR per person.
There is no public transport between the villages. As the area sees few visitors there is no need for it. It is possible to rent a motorbike from villagers for negotiable price.

Despite of quite unknown status of this area it has surprising number of places of natural beauty and can be a real find for people venturing here. Labuan Cermin- fresh/seawater lagoon surrounded by lush forest is a good place to have a refreshing swim and enjoy amazing natural surroundings. From Teluk Sulaiman village, there are boats departing to Kaniungan Besar island which has quickly become a highlight of there area, with its beautiful coral reefs, amazing beaches, sea turtles, spectacular views and a feeling of remoteness. One can also visit an uninhabited Kaniungan Kecil island 30 minutes away by boat. At sunset and/or sunrise Proboscis monkeys come to the mangroves next to Teluk Sulaiman village but the place is accessible by boat only. A trip can be organised from Teluk Sulaiman or Kaniungan Besar island. There are 3 waterfalls in the last village of the area Teluk Sumbang. Two of them are quite close to the coast (5 and 15 min), for the last one and the most beautiful Air Terjun Bidadari one has to walk about 1 hour through the jungle path, just ask for a local guide in the village. Teluk Sumbang village is also home to a local Dayak tribe people, where you can buy local handcrafts, mostly made of 'rattan'.
Lamin Guntur Eco-Lodge offers Scuba Diving packages (600 000IDR per 2 dives). There are 15 known dive spots in the area. The whole area around Kaniungan Besar island and Lamin Guntur Eco-Lodge is great for snorkelling as well with colourful coral reefs and plenty of sea turtles.
There is a good potential for a jungle trekking in the area as most of it is still covered by forest but these activities are yet to be organised. Adventurous travellers can try to find local guide independently.
There are plenty of warung (local food stalls) in the villages. Up do date there is no western food available. Basic necessities can be bought in one of the local shops.
There is no place to buy alcohol.
Overall the place is quite safe and has a friendly feeling to it. Just like everywhere else common sense safety is advised.
