bachelor party

i live in souteast texas and im looking for a place to have my bachelor party in october. the idea is to find a place that has a place to kayak, significant mtn bike trails and also we would be able to camp there for a long weekend. ive been told there are places like this in austin that not only fit my description but also rent bikes so that my groomsmen that dont have bikes can rent one for the weekend( and yea i dont know why i even asked them to be in the wedding when they dont even ride... what was i thinking) so let me know if any of yall are from the austin area and know a good place to go
