Tramping

I wasn't sure about the puncuation, so any suggestions would be great.

Walking through water
My feet cold and wet
The bridge we will cross
will swing beneth us

My shoes sink in mud
all squishy and brown
Jumping over rocks
Slipping and sliding

Wonderful forest
The trees tall and green
The bushes are low
mixed in with ferns

The hill is so steep
Almost have to crawl
Just to reach the top
And enjoy the view

Eat lunch looking out
At bushland and hills
We will continue
very soon indeed

Walk down through the bush
And run into trees
The plants around me
Brush against my leg

We walk back to camp
After a big tramp
So tired and sore
We lay on the grass

Nice. You tell the story quite well. Personally I think your punctuation is fine but then again I'm no expert.

My shoes sink in mud

in the mud? Maybe that would sound better?

Wee lay on the grass

'We lay on the grass' would be more appropriate.

Your poem is very good but perhaps a little to two dimensional to me. It tells a nice story and that is it. It's great but nothing really stands out but that's just me . Anyway, great job!

edit: I found out you where twelve! wow, that just makes you more amazing.
