So, getting to Martini Junction can be a challenge, but it's really not too difficult.            

1. Park respectfully at the end of Robinwood Ave. 

2. Enter the forest at the end of the street and follow the "White" trail to the right. It's shown on the map as black but no matter just follow it for about ten minutes and then watch for the Orange trail on  the right. 

3. Follow this Orange trail for maybe another ten minutes or so and you're there!  Little Birdhouses with appropriately colored roofs will keep you on track.
