To me there is no greater joy that driving around the island, seeing the sights, going on adventures, and camping in beautiful places. Here are the GPS coordinates of some of the best places I've camped at recently. You can also view last year's list here: Top 7 Camping Spots in Taiwan - 2016
Hsinchu: Lingkou Skyway
This elevated walkway sits at the top of the ridge with panoramic views on both sides. It's at 1100 meters above sea level, which is a great elevation to beat the heat in the summer.
Hsinchu County, Jianshi Township
GPS: 24.699933, 121.262403
Miaoli: Donghe Campgrounds
This is a beautiful and free public campground on the way to Valley of the Gods Waterfall. It has many parking spaces and places for tents, but no bathrooms or running water.
Miaoli County, Nanzhuang Township
GPS: 24.598247, 121.040972
Miaoli: Liyutan Reservoir
There is a large platform overlooking Liyutan Reservoir. It offers expansive views and easy access. There are some structures there which offer protection from the wind, but not from the rain. There are bathrooms, but they are closed at night.
Miaoli County, Sanyi Township
GPS: 24.339006, 120.778771
Taichung Riverside Park
Large, central, and easy to access. It's in a very convenient location for road-trips around the island.
Taichung City, Dongshi District
GPS: 24.254293, 120.824754
Nantou: 921 Earthquake Lake
Around the park there are dozens of places to camp. The main road to Sezikeng is partially blocked by large stones, so wide cars have to park at Jiucaihu, or drive up through the lower road, which is easier in a 4WD vehicle. Motorcycles and narrower cars can drive in through the front. There is also a large covered pavilion with bathrooms.
Chiayi: White Horse Pavilion
This large pavilion overlooks Tsengwen Reservoir. It has a spectacular view of Dapu and the surrounding area and is well protected from the rain. The road up to the pavilion very steep and in poor condition though. Motorcycles and 4WD cars will have no problem, but it's not a suitable road low cars or new drivers.
Kaohsiung: Lakesi River Swimming Pools
Just before the swimming pools there is a very large, open flat area that's just perfect for camping. It's a great place to hang out with friends around a campfire and have a few beers. It's also the trailhead for accessing Fuxing Landslide Lake.
Taitung: Dapo Lake
This cozy pavilion is right on the edge of Dapo Lake with beautiful views of the lake and mountains. Scooters can drive up to it at night but campers traveling by car will have to parking lot, which is also a nice place to camp.
I hope you enjoy your trip around the island. Just remember that these campsites are public places. So please keep them clean, and if you camp at a pavilion, take down your tent early so that morning visitors can use them too.
