The deadwater is receiving a bit of TLC at the minute so sections of it are closed. What parts of it are open are still worth riding though – some great stuff. Whatever you do don’t bypass the blue – the note about it being suitable for tagalongs is a load of crap. After the initial fireroad climb it transforms into the most wonderful, fast, flowing singletrack. It’s a great ride out and if it had more jumps / drops (i.e. a red grade) people would rave about it.
Skydive (last part of the lonesome pine) is a fast, flowy red grade (nothing techy on it though) descent.
After an all dayer combining 2 trail centres:

You could ride from Leaplish on the lakeside way to the trail head – it’s about 8 miles IIRC.
Plenty of natural stuff too although you’ll need a guide / ask at the bike shop at the trail head.
Don’t forget your insect repellant.
