Khun Si Viewpoint
Perched in the hills of Koh Samui on the shortcut road between Lamai and Mae Nam, this quiet viewpoint rewards visitors with broad panoramas across the island's interior mountains and surrounding seascape. Unlike the island's busier coastal attractions, it draws a small, unhurried crowd, and the journey up — winding through pure nature along a road that mixes asphalt with dirt sections — is considered by many visitors to be as rewarding as the destination itself. At the top, a single caretaker manages a small parking area for scooters and can provide light refreshments. The viewpoint also serves as a starting point for those heading to Khun Si Waterfall. The atmosphere is calm and largely undeveloped, making it a genuine off-the-beaten-path stop for travellers willing to explore beyond the beach resorts. Good to know: the road conditions make this accessible only by scooter, bicycle, or a capable 4x4 — standard cars are not suited to the climb, and reviewers recommend an automatic 125cc bike or above for the easiest ride. Sections of the road are unpaved, so take the descent slowly. Arriving before sunset offers the best views and light, and visiting during the dry season (December to April) improves visibility considerably. No formal opening hours are listed, so plan to arrive well before dusk.

Visitor Reviews
This place is on the shortcut road between Lamai and Mai Nam. You can get here by bicycle, motorbike or car. I'd recommend an auto 125cc bike or above - my friend struggled with manual gears on this road. Also drive carefully as there are many corners (windy roads) and there is a lot of sand that makes the road slippery. If you are an experienced uphill cyclist, it's a great challenge to take on - prepare for a heart thumping uphill journey and a relaxing sail back down after all the hard work getting up. FYI - there are also some tours that will stop here on the way to other activities in the area. I'd plan 5 to 10 minutes here for a couple of pics and vids.
Parking point for scooters only and single caretaker can provide light refreshments for visit to Khun Si Waterfall and beautiful views of the interior mountains of Koh Samui. To reach the viewpoint, the track is partly concreted, mainly sand and rock, difficult to negotiate, potholed, heavy going and remote. Car driving tricky and furthest parking would be the Chilling Hill restaurant before walking the remainder. Waterfall is a ten minute walk from the viewpoint along a sandy, rocky track downhill, suitable shoes and water needed. No other facilities.
The location is very beautiful, sadly we got there too late for the sunset. If you go with a scooter, don't drive too fast, because some some parts of the road are only dirt, no asphalt. From the viewpoint you can also go down to the waterfall, takes around 10 minutes.

Tips for Visiting Temples & Culture
Dress Modestly
Cover shoulders and knees at all temples. Carry a light scarf or sarong — some temples lend wraps, but not all. Shoes come off before entering any building with a Buddha image.
Mind Your Feet
Never point your feet at a Buddha image or a monk — it's considered deeply disrespectful. When sitting inside a temple, tuck your feet behind you or to the side.
Ask Before Photographing
Exterior photos are almost always fine, but some interior halls prohibit photography. Look for signs, and never pose irreverently with Buddha images — it's a legal offense in Thailand.
