## Bukit Batas, South Kalimantan: Hiking Above Riam Kanan’s Island-Studded Lake

Bukit Batas is one of those places that looks like a composite image: forested hills, a wide reservoir, and dozens of small green islands scattered across the water. This natural lookout in South Kalimantan is still relatively low-profile outside Indonesia, but it’s firmly on the radar for hikers and weekend campers from Banjarmasin and Banjarbaru.

From the top, you’re looking straight down on the Riam Kanan reservoir and its chain of islands, a view that’s frequently compared to a “mini Raja Ampat” in Borneo.

This guide walks through how to get there, what the hike is actually like, and the on-the-ground logistics you should know before you commit to that early-morning start.

## Where Is Bukit Batas?

Bukit Batas is a natural hill viewpoint in Desa Tiwingan Baru, Aranio District, Banjar Regency, South Kalimantan, Indonesia.

Key geography:

– Overlooks Waduk Riam Kanan (Riam Kanan Dam & reservoir)
– Within the wider Meratus Geopark landscape, a protected area recognised for its geological and ecological value
– Roughly 1.5–2 hours by road from Banjarmasin to the lake jetty, depending on traffic and where you start in the city

Tiwingan Baru itself has been officially promoted as a desa wisata (tourism village) since 2019, with Bukit Batas, Pulau Pinus II (Pine Island), and nearby hills as its flagship attractions.

## What Makes Bukit Batas Special?

### The “Raja Ampat of Riam Kanan”

From the summit you’re looking down on:

– A wide, calm reservoir framed by low hills
– Dozens of small, irregularly shaped islands and peninsulas
– Fish farms and scattered lakeside houses

Several Indonesian sources and visitor reviews explicitly compare the panorama to Raja Ampat in West Papua, because of the clustered green islets dotting the blue-green water.

You’re not getting coral reefs here – this is a reservoir, not a marine park – but visually it scratches a similar itch: wide-angle landscapes, layered hills, and soft light at sunrise or sunset.

### Part of the Meratus Geopark Story

Riam Kanan sits inside the Meratus Geopark, an area shortlisted and then recognised as a UNESCO Global Geopark for its ancient rocks, forests, and Dayak cultural landscapes.

Nearby geosites include:

– Matang Kaladan panoramic hill – another viewpoint over the reservoir
– Kahung tropical forest – with rare orchids and carnivorous pitcher plants News

If you’re building a broader Kalimantan itinerary, it pairs naturally with other Meratus stops (rafting, forest walks, floating markets). An internal link from your main Indonesia or Borneo guide here will make sense for RealJourneyTravels readers.

## The Hike: What to Expect on the Trail

### Starting Point: Boat Across Riam Kanan

Most visitors reach Bukit Batas via the Riam Kanan jetty area in Aranio:

1. Drive to the Aranio / Riam Kanan pier
– About 1.5 hours by car from Banjarmasin under normal conditions.
– Parking at the pier has been reported around IDR 10,000 per car in older TripAdvisor reviews. This price is from 2020; treat it as indicative only.

2. Charter a klotok (small motorboat)
– Visitor reports describe a 20–30 minute boat ride across the reservoir to Pulau Pinus / Pulau Pinus II, which acts as the usual trailhead.
– Group boat prices have been quoted at around IDR 350,000–400,000 per boat in sources from roughly 2019–2020. News
– Price warning: these figures are several years old and fuel costs have changed; confirm the current rate with boat owners on site or via your accommodation.

From Pulau Pinus, you continue on foot (or by ojek) up the hill.

### Ascent: Steep but Short

The hike up Bukit Batas is short but punchy:

– Distance: older descriptions mention roughly 3 km from the lake edge to the summit area.
– Time: most visitors report 40–70 minutes of climbing, depending on fitness and how often you stop for photos.
– Trail conditions:
– Mainly dirt and small rocks, often quite steep in places
– Can be slippery after rain
– Some sections may have basic steps or simple improvements near busier viewpoints

An AllTrails listing for the area describes Bukit Batas as a moderate hike, highlighting the steep sections but rewarding views over the islands of the Riam Kanan reservoir.

If climbing steep hills in high humidity is a challenge for you, consider:

– Starting before sunrise to avoid the worst heat
– Using local motorcycle taxis (ojek) for part of the way, where available – older sources mention this option on similar hills around Riam Kanan, though availability may vary day-to-day. News

### Summit Area: Viewpoints and Camping Spots

At the top, expect:

– Open viewpoints with broad sightlines over the reservoir and islands
– Simple camping clearings, used by local visitors who stay for sunrise or star-gazing

Official information from the Tiwingan Baru tourism village recommends camping at Bukit Batas as a highlight, alongside glamping at Murung Batulaba and family trips to Pulau Pinus II.

Because this is a community-managed nature spot rather than an intensive resort, you shouldn’t expect manicured viewpoints everywhere. Some angles will still require a short scramble or stepping over uneven ground.

## Facilities on and Around Bukit Batas

Information on facilities is scattered and a bit dated, so it’s worth separating what’s been documented from what may have changed.

### Documented Facilities (Check for Updates Locally)

An Indonesian travel piece from 2019 notes the following facilities for visitors heading to Bukit Batas and Pulau Pinus:

– Small food stalls / simple eateries near the lake and camping areas
– Basic toilets and washrooms
– Local guides and ojek (motorcycle taxis)
– Designated camping zones for overnight stays

Tiwingan Baru’s official tourism-village listing continues to promote camping at Bukit Batas and glamping at Murung Batulaba, which implies ongoing visitor infrastructure as of recent updates.

### How to Interpret This in 2025+

– Those facilities did exist and are still mentioned in recent tourism-village materials.
– Exact opening hours, cleanliness, and how many stalls operate will depend heavily on weekends, holidays, and local demand.
– As with many community-run hill viewpoints across Indonesia, some services might be minimal outside peak times.

Practical approach:

– Bring enough water, snacks, and a power bank as if there were no shops, then treat anything open as a bonus.
– If you have specific accessibility needs (e.g., reliable toilets, certain food), ask your guesthouse in Banjarmasin or Banjarbaru to call ahead and check.

## Fees, Tickets, and What’s Likely Outdated

Different sources mention a small entrance fee payable to the local community:

– A 2019 article cites a ticket of around IDR 5,000 per person, collected by neighbourhood officials before the hike.

Again, that’s pre-pandemic pricing. It’s reasonable to expect that:

– The fee amount may have changed
– The way it’s collected (village post, trail gate, combined boat+entrance package) might be different now

Because this is a community-managed hill under the umbrella of local tourism and the Meratus Geopark, it’s normal – and good practice – to pay whatever official contribution is requested on site. It goes toward trail maintenance, waste management, and community income.

Bottom line: treat all specific numbers (parking, boat fare, entrance ticket) as historical benchmarks, not guarantees. Confirm current costs with local operators before you commit.

## When to Visit Bukit Batas

### Seasons and Weather

South Kalimantan has a tropical climate with rainfall year-round, but it does have a noticeably drier period roughly from May/June to September/October, with heavier rains from around November to March. on a shoestring

For Bukit Batas specifically:

– Drier months (roughly May–October):
– Trails are less muddy and safer underfoot
– Visibility is more reliable; afternoon storms are still possible but generally shorter

– Rainier months (roughly November–March):
– The path can get very slippery, especially on steep dirt sections
– Afternoon thunderstorms are more common

Local and official sources for Bukit Batas and Tiwingan Baru explicitly recommend visiting in the dry season to avoid slippery trails and to maximise views.

### Best Time of Day

Visitor photos and local posts highlight two prime windows:

– Sunrise: soft light over misty islands, cooler temperatures during the climb
– Late afternoon toward sunset: warmer tones on the water, but you’ll descend in fading light – bring a headlamp if you linger.

If you camp, you can enjoy both without doubling the climb.

## How to Get There: Step-by-Step Logistics

Here’s a simplified sequence you can use in your own trip planning:

1. Base yourself in Banjarmasin or Banjarbaru
Both cities have road access toward Riam Kanan and regular accommodation options.

2. Arrange transport to Riam Kanan / Aranio jetty

– Allow 1.5–2 hours from central Banjarmasin in planning, giving room for traffic and breaks.

3. At the jetty:
– Park your vehicle (paid parking is standard; historic rate ~IDR 10,000 per car).
– Negotiate a klotok boat charter to Pulau Pinus / Bukit Batas trailhead and back.
– Clarify:
– Total price per boat (not per person)
– Maximum passenger count
– Waiting time or pick-up time on your return

4. On Pulau Pinus / trailhead:
– Pay any posted village or hill entrance fee.
– Decide whether to walk or hire an ojek for part of the climb, if available.

5. Hike and enjoy the summit views, leaving enough margin to return before dark if you’re not camping.
