The letterbox is set at a point between Bishanyan (碧山巖) and Baishihu (白石湖) where is a starting (or end) point of Taipei Grand Trail (TGT) Section 5. Transportation here is very easy, whether you drive or take a bus (S2 and S2 shuttle), so the place is also a hub for many nearby tourist destinations.
You might be intersted in these tourist attractions:
- Bishanyan (碧山巖): This popular temple commands a bird's-eye view of the scenic surroundings of Taipei Basin.
- Zhongyong Mountain (忠勇山): Do a little exercise to hike to the top (H315M) and enjoy a beautiful scenery.
- Baishihu Suspension Bridge (白石湖吊橋): The bridge features a straight abutment which gives it a cable-less and invisible style that blends perfectly with the surroundings.
- One Heart Pool (同心池): The romantic pool features pastel-color flowers in the shape of a heart.
- Husband and Wife Tree (夫妻樹): You can take a rest under the shade of two beautiful trees.
