Stand at the junction of Jalan Jenderal Ahmad Yani where it runs past the Lambung Mangkurat Museum, and you are on the road that carries most of Banjarbaru's public life. The city sits at the foot of the Meratus Mountains, about 35 km southeast of Banjarmasin, and its parks and central city hall reflect the European-influenced planning of D.A.W. Van der Pijl.
Banjarbaru suits travellers who are already in South Kalimantan and want a quieter base than Banjarmasin, with the diamond fields of Cempaka and the mosque and markets of neighbouring Martapura within easy reach. It rewards a slow half-day rather than a rushed checklist.
This guide covers the sights and activities the sources describe, followed by a one-day plan built only from those places and answers to the questions travellers ask most often.
Top things to do in Banjarbaru
1. Lambung Mangkurat Museum
On Jalan Jenderal Ahmad Yani at km 36, this museum holds historical and cultural relics alongside displays on South Kalimantan's life and natural potential. Its collection includes relics of the Sultanate of Banjar, material from Candi Agung and Candi Laras, stone tools, wood carving, agricultural and household implements, and traditional musical instruments. It was inaugurated and began functioning in January 1978.
Allow time to read the labels rather than walking straight through, since the collection is the main structured introduction to the region's history. You can call ahead on +62 511 4772453. Pair it with the rest of your Jalan Jenderal Ahmad Yani stops so you are not doubling back along the same road.
2. Diamond panning in Cempaka
Cempaka district lies about 7 kilometres from Banjarbaru, and its diamond mines have existed since the 15th century under the Hindu-Buddhist kingdom Negara Dipa. Miners usually work in groups, digging a hole roughly 10 to 12 metres deep with traditional tools and old methods.
This is a working mining area rather than a staged attraction, so go to watch and understand the process rather than to handle equipment. Keep your distance from the edges of the pits and follow the lead of whoever is on site. Combine the visit with the Cempaka district itself, which is the least densely populated part of the city.
3. Great Mosque of Al-Karomah Martapura
The Great Mosque of Al-Karomah Martapura stands on Jl. A. Yani in Cindai Alus, in Martapura, just north of Banjarbaru. Martapura lies immediately to the north of the city and in effect forms an extension of it, so the mosque fits naturally into a day based in Banjarbaru.
Dress modestly and time your visit outside prayer times if you want to look around without disturbing worshippers. Because it sits on the same road axis as the museum, it works well as the second half of a north-south run along Jl. A. Yani.
4. Amanah Borneo Park
Amanah Borneo Park is on Jl. Taruna Bhakti in Palam, within Cempaka district, and is open from 09:00 to 17:00. It is the most straightforward family stop in the city, with a fixed daily window that makes it easy to slot into a plan.
Arrive in the morning if you want the cooler part of the day, since Banjarbaru has a tropical rainforest climate with rainfall in every month. It sits in the same district as the diamond panning sites, so the two can be combined in a single trip out to Cempaka.
5. Swimming at Kolam Renang Idaman
Banjarbaru has one public pool, Kolam Renang Idaman on Jalan Taman Gembira. It is a simple option for a hot afternoon, and the equatorial climate keeps temperatures uniform through the year.
Bring your own swimming gear, as this is a public pool rather than a resort facility. It pairs well with an afternoon in the city centre, where the parks and city hall are concentrated.
If you only have one day
Morning: Start at the Lambung Mangkurat Museum on Jalan Jenderal Ahmad Yani km 36, while the day is still cool, and give the collection proper time.
Afternoon: Continue north along Jl. A. Yani to the Great Mosque of Al-Karomah Martapura, then head out to Cempaka district to see the diamond panning and, if time allows, Amanah Borneo Park before it closes at 17:00.
Evening: Return to the city for a swim at Kolam Renang Idaman on Jalan Taman Gembira, or simply walk the central parks and city hall area that give Banjarbaru its layout.

How do I get to the diamond mines at Cempaka?
Cempaka district is about 7 kilometres from Banjarbaru. The miners work in groups, digging holes roughly 10 to 12 metres deep using traditional tools and old methods, so arrange your visit around their working activity rather than treating it as a fixed-hours attraction.
Is there anywhere to swim in the city?
Yes. Banjarbaru has one public pool, Kolam Renang Idaman on Jalan Taman Gembira.
Can I visit Martapura as part of a Banjarbaru trip?
Yes. Martapura lies immediately to the north of Banjarbaru and in effect forms an extension of the city, and the Great Mosque of Al-Karomah Martapura on Jl. A. Yani in Cindai Alus is within that area.
Use this as your starting point, check the details that matter for your dates, and build your Banjarbaru itinerary around the museum, the Cempaka diamond fields and the road north to Martapura.
