In reply to Simon Lee: We ended up staying in Izola, a bit south down the coast from Koper. It is a pleasant town, much less hectic than Koper. We stayed at a hotel right along the harbor(don't remember the name but its pretty obvious), a bit pricey but not unreasonable. It was about a 20 minute ride to the crags, mostly on motorway and quite scenic. If only the weather had been better!!!! If you do have some bad weather, or just need a rest day activity, the Skocjan Caves are not far from Osp and are definitely worth a visit--very Tolkienesque!!!
