We're traveling by car and made stop due to tripadvisor. What I have to say, this is wonderfull place with very nice owner, more over, guided tour for guests was made by himself. He can show for you coffee plantation (but be carefull - a lot of spider there) and curcuma production (he has it back of his yard).
This garden isn't big, but very cozy. Also you could see how spice really look like and how they processing (sometime it's really surpriz).
If you're lucky you will have a chance to try tomato that was grown on the tree, cucumbers that look like grapes and very hot chilli that is smaller than the nail. Anyway positive emotions are guaranteed.More
