For those who aren't inclined to go to Long Dong, who like short approaches, and don't mind their routes short and slabby...
Dapaoyan (大砲岩), translated as "Big Cannon Cliff", is a high-ball boulder and/or top-rope area in Yangmingshan National Park, just above Beitou. Don't mind the "forbidden to climb" signs... all bark and no bite, kinda like the dog kennels across the road. A 45-minute walk from the MRT, or a short bus ride (runs every 30 min) with some walking, or a very short walk up the hill if you have your own transportation (parking is sparse).
Rehai (熱海) is a slightly larger, taller cliff also in the Beitou area, but outside the national park. There are around 20 bolted routes here, and some can be setup for top-roping from above. Great views of the surrounding forest and outskirts of the city. Can be walked from the MRT in 30 minutes, or in 5 minutes from the trail entrance if you have your own transportation.
Cuishan (翠山) is a fun hike, but climbing-wise is a monumental disappointment.
Check the individual areas.
There are a plethora of gyms, both indoor and outdoor. Personal recommendations are Stone for bouldering, Neihu for lead climbing, and Da Vinci for top-roping.
