Day Trips from Phnom Penh: Oudong, Koh Dach and Beyond

← Home

Phnom Penh has several solid half-day trips within easy reach, including the former royal capital, a weaving island, and a handful of quieter countryside options for visitors with an extra day to spare.

Oudong: the former royal capital

Oudong sits about 40 kilometers north of Phnom Penh and served as Cambodia’s capital for over 250 years before Phnom Penh took over in the 1860s. The hilltop stupas here hold the ashes of several Cambodian kings, and the climb up (a few hundred steps, shaded in parts) rewards you with a wide view over the surrounding countryside and rice fields. A round-trip by hired tuk-tuk runs \$20 to \$25 for the whole vehicle including wait time, or you can book a half-day tour with a driver-guide for \$30 to \$40 per person that usually pairs Oudong with a stop at a local silk-weaving village.

The site is still an active place of worship as well as a historical one, so the same modest-dress expectations that apply at Angkor Wat and other Cambodian temples apply here too — shoulders and knees covered is the safe default, and shoes come off before entering any of the shrine buildings at the top.

Koh Dach: the Silk Island

Koh Dach, known locally as Silk Island, sits in the Mekong just a short ferry ride from the city center — the crossing itself costs next to nothing (under \$1) and takes about 10 minutes. On the island, small family-run workshops still weave traditional Khmer silk on wooden looms, and most welcome visitors to watch the process for free or a small donation, with scarves and textiles for sale directly from the weavers. Renting a bicycle near the ferry landing (\$2-3 for the day) is the best way to explore the island’s quiet dirt roads past stilt houses and fruit orchards.

Choosing a day trip that matches your time

If you only have a half-day, Koh Dach is the easier win — close, cheap, and low-effort. Oudong needs closer to 4-5 hours round trip once you factor in the drive and the climb, so it suits travelers with a full free day in Phnom Penh rather than a quick afternoon gap. Both can be combined into one long day with a private driver for around \$45-55, which is worth considering if you won’t be back this way again.

Travelers on a tight schedule who can only fit one should generally pick based on interest rather than convenience alone: Oudong rewards those drawn to history and a bit of physical effort, while Koh Dach rewards those who’d rather spend a relaxed afternoon cycling past rice paddies and watching silk being woven by hand.

Combining both into one long day

A private driver for a combined Oudong-plus-Koh Dach day runs \$45-55 for the vehicle, starting early with Oudong’s hilltop climb before the heat sets in, then finishing at Koh Dach for a relaxed bicycle ride and lunch by the Mekong in the afternoon. This pairing works well because Oudong is physically demanding early in the day while Koh Dach is a gentle wind-down.

What to bring

Comfortable closed shoes for Oudong’s stairs, sun protection since both sites offer limited shade, and small bills for the Koh Dach ferry and any silk purchases directly from the island’s weavers, who generally don’t have card payment options. A refillable water bottle is worth packing too, since there is little shade on Oudong’s climb and no reliable vendors selling cold drinks partway up.

Other lesser-known day trip options from Phnom Penh

Beyond Oudong and Koh Dach, the Mekong Islands further south (including Koh Oknha Tey, another silk-weaving community) offer a similar rural escape with even fewer visitors than Koh Dach, reachable by a slightly longer drive and short boat crossing. Kirirom National Park, roughly 2 hours from Phnom Penh, offers cooler mountain air and pine forest hiking for travelers wanting a genuine change of scenery from the flat river landscape around the capital, though its greater distance makes it more of a full-day commitment than a quick half-day add-on.

Tonle Bati, about 30km south of the city, combines a smaller Angkor-period temple with a lakeside picnic spot popular with local families on weekends — a good lower-key alternative to Oudong if you want ancient temple architecture without the crowds or the longer drive time. Phnom Tamao Wildlife Rescue Center, also within about an hour of the city, makes a reasonable half-day addition for travelers with an interest in wildlife rehabilitation.

Arranging a day trip without a tour company

All of these destinations are reachable independently with a hired tuk-tuk or car and driver, generally cheaper than a packaged tour if you’re comfortable navigating without an English-speaking guide — most drivers know these routes well even without formal guiding credentials, and a written note of your planned stops (in Khmer, which your hotel can help translate) smooths communication.

Agreeing a total price for the whole day before setting off, rather than per stop, tends to avoid awkward renegotiation partway through, and most drivers are happy to wait at each site for however long you need rather than charging separately for waiting time.

Weather considerations for these specific day trips

Oudong’s exposed hilltop climb is more pleasant in the cooler morning hours, while Koh Dach’s shaded village paths remain reasonably comfortable even during light rain, so it’s worth sequencing a combined day with Oudong first thing in the morning and saving Koh Dach for whatever conditions the afternoon brings.

Whichever day trip you choose, booking through your guesthouse rather than a street-side tour tout generally ensures a more reliable vehicle and driver, and it’s worth confirming the exact itinerary and stops included before paying anything upfront, since informal arrangements can sometimes drift from what was originally discussed.

This combination of a historically significant hilltop site and a relaxed riverine village gives visitors a genuine sense of Cambodia beyond the temple circuit within a single manageable day, without requiring the multi-hour drives that some other countryside excursions demand.
