Day 1: Banlung (Ratanakiri) – Veunsai – Siem Pang National Park

Veunsai -Siem Pang National Park is located in northeastern Cambodia. It covers an area of over 50,000 hectares with a large area of vast evergreen forests. VSSPNP riches with many Endangered and Critically Endangered species including our Cambodian National Birds, the giant ibis, leopard cats, pangolins, lorises, langurs, and especially home to the largest population of the newly discovered gibbon species, the northern yellow-cheeked crested gibbons.

08.00 our guide and driver pick you up from your hotel in Banlung and transfer you by car for 50 minutes to Tom Poun tribal village (Kachon Village). Then we continue to ride the boat on the Seasan River upstream to Koh Peak Village which is the trekking point. Start trekking to a stunningly amazing forty meters high waterfall where you can invigorate your muscle and refresh your swim before enjoying lunch. Trek back to the boat and then ride to the Kachock ethnic village (Chinese and Laotian settlement) and a short trek to observe the sacred cemetery of Kachock indigenous people, each tomb has interesting wooden man and woman sculptures. Ride the boat again downstream to Siem Pang National Park office in Veunsai to register for the Gibbon watching and get a Gibbon guide. We are transferred by motorcycle to the station for dinner and overnight.
After dinner will go out for a safari night walk to look for seeing the nocturnal species. Go to bed around 9 pm as the following day is an early grumpy morning start!

Included for the day:
Trekking: 15km
Transportation: Transfer, boat ride
Tour guide: English-speaking guide
Meals: lunch, dinner
Accommodation: Community Camp Base Site – VSSPNP

Day 2: Siem Pang National Park – Gibbon Watching – O’Ka Sing Waterfall

Weak up early today to watch the Gibbon families, our team will arrange the picnic breakfast, and coffee for you at the site.

At 4:15, whilst it is still dark follow the guide to the gibbon habitat area about 45 minutes away to make sure we are there in time to hear their calls. We then reach the edge of the grassy savannah and wait for the call of a certain family, currently the only group that accepts people in their presence. The different families start to call(sing) at around sunrise with some calls carrying up to 2km. Once the habituated group of gibbons starts their calls, the gibbon guide will try to locate them in the forest as fast as possible and he will guide them up to the spot so we can watch them in their natural habitat as they go about their morning activities in the tree canopy. In some cases, they let you come very close-less than 15 meters-which provides an excellent opportunity to take pictures. This is a special time as the gibbons can travel quickly in the trees and leave in a split second, anytime they want. Once they do, it can be very difficult for us to find them again, however, the group can often be followed for a couple of hours throughout the forest.
After the Gibbon spotting, we return to the station for lunch and then continue trekking deeper into the jungle to Virakchey National Park zone, set the campsite for dinner, and overnight at the O’Ka Sing Waterfall.

Included for the day:
Trekking: 20km
Transportation: Transfer from Pu Tang Village to the hotel
Tour guide: English-speaking guide
Meals: Breakfast, lunch, dinner
Accommodation: Hammock at a campsite in the jungle

Day 3: O’Ka Sing – Veunsai – Banlung (Ratanakiri)

After breakfast, we trek back to the station on the other loop to visit more waterfalls and different scenery. Arrive at the station at about 12.00 and have lunch. Then we are transferred by car back to Banlung. Drop off – end of services. Dinner and accommodation are not included.

Included for the day:
Trekking: 15km
Transportation: Transfer back to Senmonrom
Tour guide: English-speaking guide
Meals: Breakfast, lunch

Small agency with a personal touch We have used Merry Travel for two trips now in Cambodia and will use them again for future travel to Southeast Asia. Staff is exceptional. The lovely Sreylin was endlessly patient with my MANY itinerary changes. We spent 8 days here in Cambodia in May and decided to return this January / February for a 45 day trip throughout the country ending with a long stay in Siem Reap. The hotels were exceptional - often held we would never have found on our own. The tours were all incredible and the transport top notch. We have used the always-smiling Vuthy often to guide us with excellent temple vista it’s. Highly recommend this small agency. The personalization is unparalleled.

If you're planning a trip to Cambodia, look no further than Merry Travel If you're planning a trip to Cambodia, look no further than Merry Travel. This exceptional local company in Siem Reap operates with genuine pride for their beautiful country, and it shows in every aspect of their service.

This wasn't cookie-cutter tourism—it was meaningful travel. Sam from Merry Travel goes above and beyond in ways that truly matter. He works directly with local communities and makes a conscious effort to support Siem Reap's infrastructure and families. Throughout our travels, we felt the deep respect Sam and his team have for the Cambodian people and their culture—they ensure that tourism enriches rather than exploits the community. When you book with Merry Travel, you're not just getting an incredible experience—you're directly contributing to the local economy and helping the people who call this special place home.

Surreal 14-day group bicycle tour of backroads Cambodia - Siem Reap to Phnom Penh Our charity group of 18 over 14 days were led by Zil and his experienced team from the Siem Reap tour company - Merry Travel - beginning at the Siem Reap temples then northeast to the mighty Mekong River, then following the Mekong southward towards Phnom Penh - our cycle paths meandered through the authentic Cambodian countryside which tourists will never see - truly surreal and the best way to learn about the Cambodian history, people, food and their culture. Merry Travel team followed us with exemplary support - highly recommend this tour company based in Siem Reap for your Cambodian travel adventure. The bicycles were fantastic also. Thanks to Merry Travel and Mr Biker Saigon cycle tour teams.

Amazing self-guided bike tour in Cambodia! Just completed an amazing self-guided bespoke ebike tour with Merry Travel/Cambodia bikes. We are both 60 plus regular cyclists who normally travel ourselves, however with little planning time and this being our first visit to the region sought local guidance. So glad we did. The planning, which was initially done through Mr Biker Saigon, as we were doing similar tours in Vietnam, was seamless and provided for a more interesting tour than had we planned it ourselves. We provided a rough 'request list' and timings and they proposed routes incorporating several additional activities including trekking, kayaking and dolphin watching. Routes were provided on Bike with GPS and also a list of accommodation. All of which were in interesting places and local commmunity orientated, which we liked. The routes, which were generally on quiet and always interesting side roads and often gravel tracks - took us through amazing countryside, small villages and finally on a beautiful journey following the Mekong into Phnom Penh. We also had a vehicle which loosely followed us and our driver Makara - himself a cyclist - supported us with everything from transfers, bike maintenance when needed and interpretation. He also found us some nice coffee and food stops!! Overall a fantastic adventure. We loved the space and adventure afforded by self-guiding, but with the excellent backup support provided by Sam at Merry Travel and Makara throughout the journey. Thank-you!

Amazing experience. A group of friends spent 10 days with Merry travel cycling in Vietnam and Cambodia. It was the best trip I have ever had. We cycled thru neighborhoods in the Mekong delta. Our guide expertly provided insight and info. He was a perfect cycling guide adding a rich cultural experience as well as great biking.

5 stars out of 5. Everything was perfect. We did a tailor made cycle tour with Merry Travel. From our communication with Sam, through to the actual tour with Zil and 'T', everything was brilliant. Sam listened to what we wanted to do, the sport of places we wanted to stay and organised everything from beginning to end. We didn't want to use tourist style chain hotels, and Sam found wonderful smaller locally run hotels. Perfect for us. Zil, our cycle guide and 'T', our driver couldn't have been better. All the places we stopped for lunch and snacks were just great. Just when we thought we couldn't cycle any further, 'T' appeared out of nowhere with fresh fruit, cold water and cold towels. Absolutely fabulous.
