How to choose an East County hike
East County hikes trade ocean views for big terrain: El Cajon Mountain, Otay Lakes, Crestridge and preserves with granite boulders, chaparral and wide inland vistas. Many are longer and more exposed than coastal trails.
Before you go: a quick checklist
- Avoid midday hikes in summer; inland heat is serious.
- Carry plenty of water and tell someone your route.
- Some trails are steep and rocky; wear sturdy shoes.
- Check for seasonal closures and fire restrictions.
- Watch for rattlesnakes in warm months.
