The Pass da Costainas is one of the well-known mountain passes of Graubünden. It can be integrated with the Ofenpass and the Fuorcla da S-charl into a superb singletrail tour out of Münstertal.
From Sta. Maria, ride along the main road to Valchava, always remaining to the right of the main road, side roads, and gravel paths to Tschierv. From here, you reach the Ofenpass over the pass road. Immediately after the pass summit, you will be riding on a flowing, very traversible singletrail up Furcola Funtana di S-charl passing th Alp da Munt. Then it arrows on a steep path with steps interspersed downward, leading down to the Alp Astras (Tamangur Dadaint). The tour now leads over the Pass da Costainas with a steep, but technically less demanding, downhill ride just after the pass summit. Instead of remaining on the alpine road, now you will ride over the Alp Champatsch on the single trail somewhat beneath the alpine road to Lü. A singletrail now leads on a direct path to Fuldera. After a short stretch on the main road, keep to the right onto the next singletrail that leads back to Sta. Maria.
