In reply to Tetleysteabags:
Hello and let me start with: I'm so jealous!
I was there just over a year ago so here is what I can tell you in my limited experience:
- Do you need a partner? No. It's super easy. I was travelling on my own and in under 1 h I was already getting offers to join people. There are many solo travellers, or people who know each other from having met there on previous years and who just happen to bump into each other year after year, but above all they all seem very welcoming, so don't worry about that. You just hang around, exchange a couple of words and done!
- Renting gear: I only brought my shoes and harness. Everything else I rented there or shared with people I that were travelling with ropes, etc. The quality of the gear I rented was excellent. I was worried about this as a non climbing friend had had a bad experience with a dodgy harness in Vietnam, but I get the feeling it was with some random cheap adventure package kind of thing, not an actual climbing shop or school. The rental places in Tonsai and Thakhek had well known brands and they seemed to take care of replacing gear. Also, they're replacing all the old bolts in the Krabi area with titanium ones, as the weather+kind of rock combo there was quickly deteriorating the previous bolts (you'll definitely hear about their Thaitanium Project once there). They know what they're doing and care about safety, don't worry about that. The guide states which routes have titanium bolts too, and which routes have dangerous bolts. So you'll be in safe hands.
Now… about your destinations… I honestly think you should reconsider going to Thakhek. Van Vieng was alright, but Thakhek was really good. Green climbers home is basically a bunch of bungalows between 2 walls with about 400 routes, the closest are something like 3 min from the bungalow and then you just walk 30 min in any direction and keep finding more and more sectors. There's always one wall on the shade, and then there's a massive roof with permadraws, a dream if you want to project something harder. Apart from the bungalows, there's 2 restaurants/bars/social areas (there's 2 camps, 8 min walk apart, so 1 restaurant/social area per camp) and that's about it. You rock up at breakfast, make plans for the day with whoever is there, and off you go, a whole day of climbing. For rest day you have some options: hiking to a pool cave, the famous motorbike loop, hitchhike to the actual Thakhek (nothing too exciting in town, but for a change or to go to the market, or to get cash! it was cash payments at the time but they've literally just changed management, so check their website to see if this has changed).
Then Tonsai/Railay is fantastic, but you're already considering it so I don't need to convince you haha they are walking distance from each other, so it all depends if you prefer more of a hippy climber kind of vibe (Tonsai) or some more villas and regular tourists mixed with climbers (Railay). Personally I stayed in Tonsai and loved it. But as I said, it's walking distance, so not a big deal.
Any questions just ask. This answer is long enough as it is, but happy to bore you to death with more info haha oh yeah: be ready for mosquitoes in Tonsai. Thakhek seemed to be better in this respect.
