Quick update, lots of leeches even at the Huai To Waterfall at this time of year. Daily rain keeps the ground moist, leeches like those conditions.Last time I tried to walk the mountain trail it was a weekend and I met rangers with a trekking group on the path who turned me around. If hiking independently it's not recommended to go on a weekend for this reason, high risk of a wasted journey in dry season, maybe less risk in rainy season but then you might not get much of a view from the top if it's cloudy. Unlikely to meet any staff on the path on a weekday. I took the path on the left side of the river that time and it was very clear and easy to walk, so maybe go that way instead of the riverbed way. It's marked as a dotted line on the BCN app.
Regarding the Dragon Crest Trek near Ao Nang, mentioned earlier, there is no guide requirement for that one but there's no public transport to get there. Sleeper Hostel in Ao Nang run a shuttle service every Tuesday and Friday for 300 baht. Go in the morning roughly 10am and back mid-afternoon. You don't need to be a guest.
Photos below are from the Tiger Cave Temple viewpoint, I stayed here late after sunset, there's a nice breeze and no mosquitos. I think the bats are eating them. Lots of insects are attracted to the lights and the bats come for the insects. I had a hard time trying to photo the bats, I prefer them when they are hanging upside down. When they are in flight you have to find a well-lit area, predict their flight path, prefocus the camera and then press the shutter slightly in advance when you see a bat coming. Maybe with a more expensive camera there would be less shutter lag.
The horizon glows green in the evenings, it's the squid fishing boats:

Monkey grooming:
I saw this Malayan Pit Viper on the main road whilst walking to the temple, it was dark and I nearly stepped on it. This is the second one I've seen, both in South Thailand and both about 30cm from the edge of the road. Careful where you are walking!
A better bat photo, I got this one in Trang. That day all the flying ants were emerging in swarms on Koh Libong and there was a feeding frenzy all around me with bats, geckos, squirrels all getting in on the action:
