Joshywashington has 7 days, a car and a camera in Mexico to explore Mayan ruins and join volunteers to document sea turtle nesting.
With only a week to pack in as much exploration as possible there are a few principals to follow. Be light on your feet; this means renting a car and making the most of each morning, afternoon and night. Explore outlining regions and keep plans loose to accommodate last minute trip revisions.
Focus your attention; some of the best advice given to me was to not try and do and see too much. Focus on one or two towns and take day trips from there. With just a few days you don’t want to constantly on the road.
