There are 3 sacred sites inside our guild base: forest, mountain, and water. The following is a guide for how to get to them. Note, however, that getting to the mountain and water sacred sites would require air dash and triple jump.
(For a guide to determining which of the 3 environments is best for you, consult this table (http://ageofwushu.wikia.com/wiki/Sacred_Sites).)
These are the general coordinates of the 3 sacred sites:

The forest place is very easy to get to. It is basically behind the stables.

The following is about how to get to the other two sacred sites. First of all, get to the inner left hand corner of the base (the corner between the Warehouse and the Main Hall).

Jump onto the roof.

Turn right, and continue on (in the direction of where the Main Hall is).

Jump up a bit.

Jump to the roof on your right hand side.

Jump onto the roof in front of you. Get to the highest roof of that building.

Here would probably be the trickiest part. You have to get from the roof to the mountain that should have been at your left hand side. Obviously, air dash is necessary here. You might also want to jump thrice before initiating air dash in order to cover more distance in the air.

If you've successfully gotten to the mountain side, then all the hard part is done. From here, if you turn left, you'll go to the mountain sacred site. If you turn right, you'll go to the water sacred site (the directions are reversed in the picture because my character turned around).

Here is the mountain sacred site!

To the left of the word, Wuxia Mountain, you can just run up to get to the mountain sacred place. No need any flying skill.

To get to the Mountain or Water site without Air Dash:
1. Run past the Practice Square in the base towards the bridge linking the West and East wing
2. Jump down from the bridge and head towards the steps (yellow circle)
3. Make your way pass some rocks and you will reach the Water site (move further west if you want to get to the Mountain site)
I've tried both methods just now. It's impossible to go by the mountains to the sacred site because I kept getting the message "This is the edge of the scene." It is also impossible the cross the bridge, because we haven't yet purchased the eastern portion of our guild base. =(
You can jump off the bridge but not cross it.
Just some info, the boost seems to be minimal and does not change the amount of TP per day.
Usually, doing a 25 round and then a 10 round daily at a sacred place would be enough, provided there is 10 people and no one misses. However, it's the same for places without bonuses (Common). However, these Sacred places are a great location to afk and cultivate skills.
