We named it Boomerang, because of the shape of the property.  It sits alongside a paved road just 3 Km NW of the tourist town of Chiang Rai in northernmost Thailand. It's a fifteen minute stroll to the large Mae Kok river, where there are other climbing crags. The rock is limestone karst, and there are dozens of gnarly climbing areas of all skill levels at our site.
We also have two side by side zip lines (flying fox, for our Brit friends).  They stretch 160 meters, coming down from the cliff face, to the meadow below.
Top quality equipment on site.  Safety is #1.

The map above shows directions to Boomerang: Park. It shows the area directly north of Chiang Rai town. From the 2-lane Mae Fa Luang bridge, go 1 km north.  Then take a left at Soi 5 and go two Km west. We're on the right, as the road curves to the left. We're between two Buddha caves, one is a half Km before, and the other is a half Km after Boomerang Park.
Best times to arrive at the park:  10 am or 1 pm (by appointment).   Activities go on until late afternoon.

Typical schedule of activities:

>>>>   Nearby trek to Three Bears Cavern at nearby 'Lion Hill' alongside river (each of 3 chambers has a natural skylight, and the cavern goes all the way through the Limestone hill.

>>>>   Back at Boomerang Park,

>>>>   Put on safety harnesses, and get going with two balancing acitivities. The first is our newest, called 'Walk the Log' - a 42 foot log placed horizontal, 4 meters above ground. It goes from the rock to our largest tree.

>>>>  Then over to nearby slack line walking (a.k.a. 'tightrope'). Both this and 'Walk the Log' have overhead safety cables.

>>>>   Rock climbing at Boomerang Park. Top quality equipment, including climbing harnesses and 11 mm ropes, available free at site. 

>>>>   One or more zip trips on our 160 meter zip lines.

Other activity options:  

>>>>  Traverse routes using fixed safety cables - two 6 mm steel wires for each route.
Currently, there are four routes with safety cables, as long as 18 meters and as high as 17 meters.

>>>>  Scramble up rocks in 'Hidden Ravine' to summit of 90 meter rock wall

Note: this is not a 'fixed' schedule, and you can adjust the activities to suit yourselves. The key is safety, while having an enjoyable and challenging time.

There are three 'tiers' of climbing routes on the hill.  Each is from 50 to 60 feet high, much of it vertical. Obviously, most climbing activity will be at the first tier, because it's most accessible from the ground level. The first tier has about 20 routes, and there are several no-yet climbed routes in the vicinity. 

Ideal for special occasions, such as school outings, birthday parties, team building events, or groups. Plan ahead to schedule. BIG discounts for groups, whether adults or children or mixed (example: father and sons). Great site for camping out, with facilities and restaurant on-site.

There are some cool projects you can assist with.  We offer free place to stay (nice and secure with kitchen and hw shower).

In your free time, you get use of our climbing equipment - plus use of a bicycle. Chiang Rai town is nearby. 

Here's a partial list of what needs tending to:

Clearing climbing routes is the main task, but there are also a bunch of other things which need attending to: at the kitchen, painting signs, doing maintenance, training beginning climbers, etc.
