There are a few Warp Points that making traveling around Hyrule
a lot easier...
Goron City to Lost Woods: In Goron City, look at the bottom
ledge. Blow away the rocks with a few bombs and you'll find a
Warp Point to the Lost Woods. In the Lost Woods, just look for
a big statue thingie...
Lake Hylia to Zora's Domain: In Zora's Domain, just look for
a hole underwater. In Lake Hylia, again, look for a few statues
around a hole. Note that you need the Silver Scale to use this.
Lost Woods to Zora's River: This is right by the waterfall
in Zora's River, and in an open area in the Lost Woods. Just swim
down! Requires Silver Scale.
