Park Ranger Unit 4 (Tub Kak)
Tucked into the natural landscape of Tambon Nong Thale in Krabi, this national park ranger unit serves as the base for a popular jungle hiking trail that rewards walkers with a stunning panoramic viewpoint. The views from the top are widely praised by visitors as something photographs simply cannot capture, making the climb well worth the effort. The surrounding jungle is lush and beautiful, and the trail itself offers a genuine taste of southern Thailand's natural environment away from the coastal crowds.
Visitors can expect a moderately challenging hike, with the ascent typically taking around one and a half hours and the descent around one hour. Park rangers are present and known for being helpful and welcoming. A small freshwater river near the entrance at the base of the trail makes for a refreshing stop on the way back down, offering a pleasant contrast to the salt water of nearby beaches.
A few practical points are worth keeping in mind before visiting. Proper footwear is strongly recommended, as the trail can be slippery and uneven, despite some visitors completing it in sandals. Mosquito repellent is essential, as the jungle environment carries a real risk of bites. Those prone to snake encounters should take care along the trail, as sightings have been reported. No opening hours or official website are currently listed, so arriving during daylight hours and checking locally for any access requirements is advisable.

you have to visit this place! and go for a swim in the little River at the entrance on the way back down to freshen up the fresh water was a really nice change after all the beaches
This is my main exercise - I've been up this hiking trail 400+ times over the last 10 years. There is a lot to say about this trail - including some warnings of snakes you might encounter. I created a huge PDF file - free - which gives all the information you could possibly want to know. Find it online at SeeKrabi. This is a 3.7 kilometer hike from the bottom of the trail to the highest peak, which is 500 meters in elevation (above sea level). Roundtrip is the same way you climb up, so total is 7.4 km. It will take a fit person about 90 minutes to climb, and 90 minutes to descend the trail. Or, if you are very fit - an hour each way - without stopping. You will probably spend at least 30 minutes at the top, so factor all of this into your plan. The trail is technical for running, but for walking, not too bad. There isn't any steep rock climbing, but they are building a couple sections of wooden steps over the difficult parts. It is hot under the rainforest canopy. Bring two liters of water for each person. Bring a snack for the top to give you energy, you'll need it. The forest gets dark around 5:30 pm. It is very dark around 6:30 pm at sunset. The trees are thick and the light does not get through. It takes some people 2.5 hours to get up to the peak, and another 2.5 hours to get down. If you twist an ankle, it will take you a long time. You will need a torch (flashlight) if you are going to be on the trail after 7 pm. Charge your phone and let someone at your hotel know you are going. There is a sign-in sheet - so put your phone number there so rangers can call if you're not back by dark and come and find you if it's late at night and you are lost or injured. Do not leave the main trail. Do return on the same trail you followed up. There is no other path that comes down to the same starting point at the trailhead. This is a national park. They will begin charging money for entrance anytime now as they are making 'improvements' like steps. The trail is not so natural anymore, they have bulldozed the path to clear it of most rocks and roots. They are still doing work to remove roots. There is one main snake you should look out for. Google the Malayan Pit Viper (Calloselasma rhodostoma). I have seen a couple of them on the trail. Their bite is horrendous because their venom is very strong. You won't die from this snake on the trail, but there will be destruction of tissue and bleeding from places you'd rather not bleed from. There are 50-300 people per day climbing the trail. You will have company in daylight. Gone are the days of 10 people on the entire trail, unfortunately! Again, get the free PDF for it - Krabi Jungle Trekking Guide – Ngorn Nak (Hang Nak) Mountain. It will help immensely. Have fun, this is one of the top things to do in Krabi. The big problem is transportation to here but SeeKrabi can handle that if you contact them.
I went by this place randomly with my scooter. The view from the viewpoint is just stunning. Pictures can't describe it. I walked to the top with my flip-flops and it was a bit challenge haha. I would definitely recommend to take a proper shoes!

Tips for Visiting Activities & Tours
Vet Elephant Sanctuaries
Only visit sanctuaries that prohibit riding, use no chains or bullhooks, and let elephants roam freely. Elephant Nature Park in Chiang Mai set the standard. If a place offers painting shows or circus tricks, walk away.
Book Popular Activities Online
Booking platforms like GetYourGuide give you instant confirmation and, on many activities, free cancellation — and you can read recent reviews before committing. Compare with local agencies for multi-day trips where negotiation might save more.
Do Outdoor Activities in the Morning
Heat and humidity peak from noon to 3 PM. Schedule jungle treks, cycling tours, and outdoor cooking classes for early morning. Water activities are more flexible since you're in and out of the sea.
