Cuyamaca has great hikes (8 miles) If that is too far try the penaquitos Water fall trail (6miles) round trip. Haha if you are going I can meet ya there I live soo close to PQ And best of all there is only downhill and flat most of the way until you leave the waterfall.-http://maps.google.com/maps?sourceid=nav��If you do message me and give me a time so I can meet you.
There are several up at Daley Ranch in Escondido and the views are stunning. Take the I-15 to the El Norte Exit where you will see the signs to Daley Ranch. Turn left on La Honda Road and take it to the end, it dead ends at the Ranch. There is a sign post at the entry with all of the trails. Enjoy!
