Hi Rafa, Hi Steve
Yes, I am reading this, Rafa! How are you doing! And you too, Steve, long time no see and all that... As it happens, I was just at Khao Yai (again) in late April. With my girlfriend in tow this time, I elected not to stay in the Wildlife Tower or camp in the forest. We asked at the HQ and they offered us a bungalow for 500 bhat (between us) straight away. It was fabulous, bathroom, towels etc although I was glad I had a little camp stove to cook on after dark, since the food places close around 5ish. The bungalows are roughly a mile from the old HQ but it's a pleasant enough walk back to the food courts/HQ and it does offer access to other trails, i.e. around the old golf course.
Steve, you do know you are going in the wet season (I assume?) unless you are planning well in advance for next winter? I've known Khao Yai to be very wet in both April and September, which are the 'shoulder seasons' for the wet season, June to August could be particularly bad, if you're unlucky.
Night-spotting without a guide is frowned upon at Khao Yai these days, as they want you to pay for their trips. I've done it occasionally and either hidden when I've seen a vehicle going down the main road, or as in the case this spring, staying on the road and seeing what the rangers say. And they said 'Stop!'. They may well be protecting you from Elephants, but I must admit I think if you're sensible there shouldn't be too much danger from them. Obviously you don't run towards them to take their photographs as some have done in the past to their cost.
Anything else you need to know, Steve, PM me.
