The village of Kria Vrisi is around 45km from the city of Rethimnon (see map below). You will need around 40-45 minutes to get there and a few more to reach the climbing area. The first routes opened from Dimitris Titopoulos (a Greek mountain guide). Since the first published routes there been a few more probably during a Cretan climbing meeting from various climbers. Unfortunately I wasn't there that day and don't have more info about those routes apart from two of them which managed to climb during my last visit.
UPDATE: Vourvachakis Thodoris sent us over the latest routes of the area. I've add them and also update a few grades which seem to be not accurate. Many thanks to Thodoris.
How to get to the area from Rethimno city.
In the area at the moment there are 25 routes with excellent protection (bolts). Routes 5a/5b/5c/5d are missing from the topo below due to been opened latetly and we've just got the information. Soon an updated topo will be added.
To get to the area you need to turn left as soon as you see the first two houses of Kria Vrisi village and follow an uphill road. Follow that off road for around 2.5km (always turn right while driving) and then you will see some red marks pointing to the path. You can park there and follow the signs until you reach the climbing sector. You will need at least 20 minutes to get there.
If you have an off road car you can continue driving for a few more meters (around 500) until you see again some red marks. Park there and start walking! From that point, the access is just 10 minutes and is recommended. However, if you don't have an off road car do not go there as you will probably stuck!
The area has two sectors. The first one which is the biggest is been described in this page while the 2nd on the next (see link on the bottom of the page).
