Firstly this is an awesome place and must visit for anyone visiting Querétaro. We went on Sunday, I think the better way to go to this place is taking a bus, it goes every hour in "Flecha azul, section B, each ticket is 64 pesos and it it's 1 hour 15 minutes to get there. The challenge is that, bus leaves when it's full. So please be patient and there is a set time but rarely followed. Other option is pay a tour but it costs 800-1000 per person. Once you get there you walk to the first point and takes about 40 minutes. Then we paid 30 pesos per person and you are allowed to get further , the next climb takes 40 min to get to the top, some parts were difficult, it can be hands and knees crawling to get to the top. Always wear comfortable shoes and clothes for the climb. After climbing we went to the small downtown area. This is one that you cannot miss. It is on way down to catch return bus. Last bus is at 6 pm, there is another final bus at 8 pm to get back to Querétaro. On the streets there's some bread seller we tried mazapán bread, it was awesome taste.
