Oh wow! I'm actually thinking of trying canyoneering when I'm in the Philippines at the end of the year. For the uninitiated, canyoneering is an outdoor activity that combines route finding, rappelling, problem solving, swimming, and hiking - with loads of jumps off high points. Been doing some research about it and while it seems extreme, it also looks fun and challenges you both physically and mentally. Plus, you get exposed to beautiful parts of nature - rivers, gorges, hiking trails etc. This blog is very informative and makes me even more excited to try canyoneering: http://www.lakas.com.ph/2015/12/things-to-know-when-doing-canyoneering-in-badian-cebu-philippines/
