What a great experience in every respect. This was my first real backpacking experience and it turned out really be a lasting adventure. Everything was handled in an excellent way from start to end. The weather forecast turned bad a week before my trip and I could easily reschedule to go a week later, and I'm glad I did.
Our guides Trey and Alice were super nice, cooked us amazing food and were always upbeat and great to talk to. Half-dome was quite scary on the way up but boy was it worth it to overcome the fear and exhaustion. It's definitely a challenge mentally and physically.
What I didn't know was that Lasting Adventures is actually a non-profit which I think makes the whole thing even cooler. What an amazing org.
Anyway, strong recommend, but do train lower AND upper body strength and endurance, it's a looot of walking, many steps, and the ropes require a lot of pulling up.
