Tunnel Trail is a great way to get to the top of La Cumbre Peak. You get to the trail head by taking Tunnel Road until it dead ends at a large water tower, there you can park your car and start on foot. You take spyglass ridge road up which is a paved fire road until it becomes dirt when you get onto tunnel trail. About three and a half miles after turning into tunnel trail you will find a massive waterfall which, after a good rain is flowing nicely. Continue past and you get to East Cielo road and its just a short distance to the peak from there. At the peak you will find an outhouse along with a table for lunch. The hike offers views back down into santa barbara the whole time and once at the top you can see out east as well.
