The most fun I've ever had while fearing for my life – that should have been emblazoned on the T-shirt I wore while traipsing through two of Tahoe's three unforgettable Treetop Adventure Parks with my daughter. If you love to scramble up tree trunks, whoosh along a zip line or experience a day in the life of a squirrel, this is the ultimate sport for you. Make no mistake, these aerial trekking courses, which snake through towering pines and cedars over bridges, platforms and zip lines, can be a real workout. Comfy clothes and a little warmup are the keys to making the most of swinging from the treetops. Open year-round, the Tahoe Vista Treetop outpost near the Nevada border is an epic forest playground with seven courses – ranked green for easy, blue for medium and black for very challenging – so you can pick and choose to suit your thrill level. There are 70 tree platforms connected by 30 zip lines and 40 bridges or traverses scattered across the treetop park.

Of course, dangling in mid-air is super fun, if you're 7 years old and giggling the whole time. Indeed, my daughter Daphne and I had such an exhilarating time, we wanted to do the Lakeview route all day long. It has easy obstacles, simple rope bridges and long, leisurely zip lines. The views of Big Blue as you soar through the sky are unparalleled. It's also pretty high up, which bothered some
