Traveling from Phnom Penh to Siem Reap in one day, stopping in Battambang, is a popular and practical way to see two of Cambodia’s most memorable experiences: the Bamboo Train and the Phnom Sampov Bat Cave. Because Battambang sits centrally between Phnom Penh and Siem Reap, it’s easy to include these attractions either as a focused one-day trip or as part of a more relaxed two-day plan (with an overnight in Battambang).
