Take subway line 4to Beigongmen, exit A, both buses 331 and 563 from here for 13 stops to Beijing Zhiwuyuan Namen. This is about a 1/2 hour ride.
This enters the Botanical Garden at the southeast gate. Basic entry 10 rmb, can buy combo ticket of 50 rmb for entry into Conservatory and Wofu Temple.
I did not like that many destinations are not listed on the Garden map(you can get a free map in the tourist office just past the entry. The Bee museum and butterfly house are both not listed. Bee museum is free between the Magnolia garden and the Mei flower garden. The Butterfly house is 10 rmb and is across from the Penjing Garden.
I wish I had more time to explore as there was a sign that said "mountain village" when walking from Wofu temple toward the arborium.
Also once you got back to the Cherry Valley area, they had a better map of that section's attractions. I liked the plank walk under the trees, it was very cool on a hot day. They were doing some construction so I could not continue past the 2nd tea house. I don't know if there was another trail leading out the other side of the tea house or not.
