Traveling to Antonito by RV

US-285 forms Antonito's main artery, running north-south through the San Luis Valley with generous lanes that handle big rigs comfortably. This highway connects you to Alamosa (29 miles north) and the New Mexico border (18 miles south). CO-17 branches west from town, climbing toward Cumbres Pass -- a spectacular but challenging route with 8% grades and tight switchbacks not recommended for rigs over 30 feet.

Overnight parking options are limited in downtown Antonito. The town doesn't permit street parking for RVs, and the few commercial lots post no-overnight signs.

Several dump stations along US-285 allow quick stops without requiring overnight stays, making them ideal for pass-through travelers heading to or from New Mexico. Check clearances carefully -- some older facilities have low-hanging canopies designed for pickup campers rather than modern Class A motorhomes.
